PEDs and the Minimum Effective Dose: Performance, Science, and ‘Safety’
(There are a bunch of disclaimers through this pointing out that this isn't medical, legal or formal advice or encouragement - it's also a very general discussion at times of different substances and compounds. I haven't strayed into detailed biological, chemical and physiological analysis - I may in the future. The even longer article complete with academic references and my actual approach and advice will be on Conjugate Cult VIP )
Performance-enhancing drugs remain one of the most controversial aspects of strength sports and bodybuilding. Conversations about their use often swing between two extremes: complete abstinence on one side, and reckless escalation on the other. Lost in the middle is a more balanced approach - one that recognises the reality of use in competitive sport, but seeks to minimise harm and preserve longevity.
This article is not written to promote or glorify PEDs. It is written for harm reduction, to give athletes, coaches, and informed readers the framework to make better decisions if they choose to use. In strength circles it has become increasingly common to hear competitors speak openly about stacking six, seven, even nine different compounds at once. While this level of transparency may break old taboos, it can also normalise excessive use and mask the fact that much less is often required to make meaningful progress.
One of the biggest drivers of high-risk behaviour is impatience. Everyone wants to be strong now, big now, and at the top of the podium as soon as possible. The long-term consequences of excessive use - cardiovascular strain, organ damage, even shortened careers - feel distant compared to the short-term allure of rapid gains. This mentality encourages escalation, pushing doses higher and higher under the assumption that more always equals faster results. In reality, the opposite often happens: the athlete burns out, health deteriorates, and progress becomes unsustainable.
At the core of this discussion is the principle of the Minimum Effective Dose (MED). In pharmacology, the MED refers to the lowest dose of a drug capable of producing a measurable effect. Applied to PEDs, it means identifying the point where performance, recovery, or physique improves in a tangible way without the unnecessary escalation of side effects.
Why does this matter? Because side effects are rarely linear. Doubling a dose doesn’t just double the risks; it often multiplies them. Elevated blood pressure, poor lipid profiles, suppressed natural hormone production, and cardiovascular strain are all outcomes that scale aggressively with dosage. By keeping use closer to the minimum threshold that still delivers results, athletes have a greater chance of maintaining long-term health, competing for more years, and keeping their bloodwork within ranges that doctors can help manage.
The minimum effective dose approach does not promise zero risk - PEDs are inherently disruptive to the body - but it does offer a framework for reducing unnecessary damage. It reframes the question from “How much can I get away with?” to “How little do I need to achieve progress?” That shift is where harm reduction begins.

Historical Context & Dosing Culture
Anabolic steroid use in sport has been around far longer than most athletes today realise. In the early days - from the 1950s through the 1970s - dosages were relatively modest, often supervised by physicians, and sometimes even supplied through official channels. Both the Soviet Union and the United States experimented with anabolic agents in Olympic weightlifting, each side aware that the other was doing the same. In this period, compounds such as testosterone and Dianabol were used at levels that would now be considered conservative, producing dramatic improvements in strength and recovery without the extreme health risks that come from chronic high dosing.
The landscape shifted dramatically in the 1980s and 1990s. Bodybuilding became the public face of steroid use, and the competitive arms race was on. As physiques grew more extreme, so did the protocols: more milligrams, more compounds, and more frequent use. The mentality of “more is better” became entrenched, spreading beyond bodybuilding into powerlifting and eventually into recreational gym culture. What had once been performance enhancement under controlled medical eyes was now polypharmacy without oversight, fuelled by underground experimentation and competitive pressure.
During this same period, PED use became widespread across many other sports. Weightlifting remained a hotbed of doping scandals, while Olympic track and field was rocked by high-profile cases such as Ben Johnson’s disqualification in 1988. In the United States, baseball faced its own reckoning as athletes like Mark McGwire and Sammy Sosa brought steroid use into mainstream headlines during the home run race of the late 1990s. Professional wrestling, though not a regulated sport in the same sense, also suffered its own series of controversies, with the physiques of its stars and the health consequences that followed drawing public scrutiny. These scandals cemented the image of anabolic use as both a competitive edge and a public health concern, leading to stronger testing protocols and harsher penalties.
Fast forward to the present day and the picture is split. On one side, the internet and social media have normalised steroid use to an extent that was unimaginable just a generation ago. Young lifters are exposed to cycles online that include six or more compounds, with gram-level weekly doses presented as standard practice. On the other side, there has been a growing movement toward health-conscious use, particularly in strength sports where careers are measured in decades rather than single contests. Concepts like “cruise and optimise” have emerged, where athletes aim to maintain performance on stable, manageable doses year-round rather than blasting aggressively and hoping to recover later.
The lesson from this history is that dose creep is real. Once a higher level of use becomes normalised, it rarely reverses. Athletes add compounds over time, often without removing anything, leading to overlapping side effects and cumulative strain on the body. The principle of the minimum effective dose is often lost in this escalation - not because it stops working, but because the culture of PED use encourages stacking and chasing faster gains rather than managing long-term consequences.
Scientific Rationale Behind MED
The logic behind the minimum effective dose approach is rooted in basic pharmacology and human physiology. Drugs do not operate on a simple “more equals more” scale. Once receptors are saturated and the primary effect has been triggered, additional dosage tends to produce diminishing returns. Athletes often escalate far beyond this point, chasing smaller and smaller improvements at the cost of exponentially greater side effects.
Keeping dosages closer to the lower end also means less disruption to the body’s internal balance. Androgens, oestrogen, prolactin, and growth factors all interact in complex ways. The higher the dose, the greater the imbalance, and the harder it becomes to manage sleep, mood, libido, and recovery without additional drugs. Lower, carefully managed doses reduce the need for constant “ancillary” compounds and make the overall system more stable.
The risk curve is another critical factor. Side effects are not linear: a moderate dose may raise blood pressure slightly, but doubling or tripling that dose can send lipids crashing, thicken the blood, and place the heart under enormous strain. Liver stress from oral agents and kidney damage from chronic high-dose use follow similar patterns. This is why athletes who escalate beyond the minimum effective threshold often find themselves in medical territory far sooner than they expect.
Ultimately, the case for MED is not just about today’s training block, but about sustaining strength and progress over years. Strength is measured in time. The athletes who remain healthy enough to keep training, recovering, and improving over a decade will always surpass those who burn themselves out after two or three seasons of reckless use. PEDs can be leveraged to extend a career, to allow an athlete to train harder for longer, and to build a foundation that compounds year after year. But they can also be abused in a way that leaves the body broken, with health markers ruined and competitive years cut short.
The science is clear: the lowest effective dose isn’t just safer - it’s often the smarter path to long-term strength.
Framework for the MED Approach
Before diving into the principles of the minimum effective dose, it has to be acknowledged that in most cases, once someone begins using anabolic-androgenic steroids or other PEDs, complete withdrawal is rare. Even if a “cycle” is followed by an attempt at post-cycle therapy (PCT), the long-term outcome is often some form of ongoing replacement or “cruise.” In practice, that means that if you take the plunge, you may be committing to some level of use for life. This reality underscores why a harm-reduction mindset is essential: the decisions made in the first year often dictate health and performance outcomes for decades to come.
The MED framework provides a structured way of approaching PED use so that gains are achieved without sliding into uncontrolled escalation. Four principles guide this approach:
1. Assess Baseline
Before adding anything to the system, you need to know where you stand. That means more than just looking at bodyweight and training numbers. Proper bloodwork is essential - covering lipids, haematocrit, liver and kidney function, hormones, and glucose control. Past experiences with PEDs, if any, should be reviewed honestly, including side effects or lingering issues. Mental health and general wellbeing also matter, as PEDs can magnify mood instability, anxiety, or compulsive tendencies. Finally, environmental and home life stability should be factored in. PEDs add stress to the body and lifestyle; if the athlete is already under financial, relationship, or occupational strain, escalation may do more harm than good.
2. Start Low
The foundation of any MED approach is restraint at the outset. Introduce a single compound, most often testosterone, at a conservative level. For some, this might overlap with therapeutic replacement ranges - essentially blurring the line between TRT and performance enhancement. The point is not to flood the system, but to establish a baseline response. This initial phase sets the tone for the entire career: start low, learn how your body reacts, and resist the urge to stack multiple agents before you’ve built experience with one. Is now very common to add Mast or Primo to this TRT baseline dose.
3. Measure Response
The purpose of PEDs is not to chase numbers on a syringe but to enhance performance and recovery in a measurable way. That means tracking more than just training PRs. Quality of sleep, mood, appetite, libido, and general wellbeing are just as important as bar speed or hypertrophy. Objective markers such as blood pressure, resting heart rate, and bloodwork should be checked regularly to ensure the internal system is coping with the external demands. A small dose that produces consistent improvements across training and recovery is often far more valuable than a higher dose that yields a volatile mix of short-term gains and worsening health markers.
4. Adjust Slowly
When progress eventually slows, the default temptation is to add more. Under the MED framework, adjustments are made gradually and only when there is a clear plateau that cannot be resolved through training, nutrition, or recovery modifications. Dose increases are incremental, not leaps, and the introduction of new compounds is carefully timed. The aim is to extend the useful lifespan of each intervention, so that the system is never pushed into the red zone unnecessarily.
Different Goals, Different Applications
Not all PED use is driven by the same objective.
Performance goals (strength, power, endurance): The emphasis is on recovery, neural efficiency, and sustaining heavy training volumes. The MED approach ensures athletes peak for competitions without burning out across seasons.
Physique goals (hypertrophy, conditioning): The goal is tissue growth and cosmetic refinement. Here, the MED principle keeps cycles sustainable and reduces the temptation to chase extreme changes at the expense of health.
Therapeutic goals (hormone replacement, injury recovery): The lowest functional dose is critical. The aim is not maximal gain but restoring balance, healing, and long-term wellbeing.
Each path requires a different level of precision, but the principle remains the same: start from the minimum, evaluate carefully, and progress only when justified.
Simplified Minimum Effective Dose (MED) PED Framework - Flowchart
Step 1: Baseline Assessment
Do you have consistent training history (2+ years of progressive strength work)?
Is your diet structured and stable (meeting protein, calorie, and recovery needs)?
Is your home life/environment reasonably stable (stress manageable, sleep regular)?
Do you have recent bloodwork (lipids, liver/kidney, hormones, glucose)?
Are you free from unresolved mental health crises or compulsive behaviour patterns?
👉 If NO to any of the above → Stop here. Work on training, nutrition, and health foundations first. PEDs will not solve instability; they will amplify it.
👉 If YES to all → proceed to Step 2.
Step 2: Entry Point
Begin with one compound only (usually testosterone).
Dose conservatively (TRT → low-supraphysiological range).
No stacking, no orals at the start. (Realistically the current trend is for people to take some sort of Test base and Mast/Primo/EQ or even Tren alongside depending on availability)
Step 3: Monitor & Measure
Track: training performance, recovery, body composition, mood, libido, appetite, sleep.
Regular bloodwork: liver enzymes, kidney markers, haematocrit, lipids, hormone balance.
Simple metrics: BP, resting heart rate.
👉 If markers are stable and performance is improving → stay at this dose until genuine plateau.
👉 If side effects worsen or health markers decline → lower dose, or consider medical oversight.
Step 4: Adjust Slowly
Only adjust if:
Training has plateaued despite diet, sleep, and programming being dialled in.
No underlying health red flags.
Adjustments:
Slight dose increase of current compound or
Add a single new agent at MED range (never both at once).
Step 5: Define the Goal Path
Performance: focus on compounds that aid recovery and neural output.
Physique: consider compounds with cosmetic/hypertrophy focus.
Therapeutic: stay within functional ranges to restore balance.
Final Check: At every stage, ask: Am I still close to the minimum effective dose? Or am I escalating without reason? If escalation is the only strategy left, reassess whether the risk is worth the gain.
Synergy and Stacking Within MED
One of the most overlooked aspects of PED use is how compounds interact. The common mistake is to treat every drug in isolation, assuming that doubling the dose of one is the most efficient path to progress. In reality, more moderate doses of complementary compounds often achieve better results with a lower side-effect burden.
The principle is simple: the body responds differently to an intelligently balanced stack than it does to extreme dosing of a single agent. For example, consider an athlete running testosterone at three times a conservative baseline. The androgenic load rises sharply, bringing issues such as elevated oestrogen, acne, hair loss, blood pressure, and lipid disruption. By contrast, that same athlete could achieve equal or better gains by combining a modest testosterone dose with a measured amount of Primobolan. The overall anabolic effect is enhanced, but the androgenic and metabolic side effects are spread out and more manageable.
This is where balancing the androgenic vs. anabolic load becomes critical. Not every compound exerts its effects in the same way. Some are harsher on lipids and blood pressure, others on the liver, others on mental health. By pairing agents with different strengths and liabilities, it becomes possible to reduce the strain on any single system. A lower dose of each also makes it easier to identify which drug is causing a particular side effect, whereas very high single-agent doses blur the feedback and leave athletes guessing.
That said, synergy does not mean stacking recklessly. Each new compound introduces its own risks and potential interactions. The more drugs added, the more complex the monitoring becomes. Bloodwork must be checked more frequently, and comorbidities such as pre-existing hypertension, sleep apnoea, or mental health challenges have to be accounted for. For some athletes, even small additions may tip the balance from tolerable to dangerous.
When used within a minimum effective dose framework, stacking is not about chasing exotic cocktails or copying what an IFBB pro might have posted online. It is about combining low doses of proven agents in a way that maximises training adaptation while keeping the health profile as stable as possible. Fewer milligrams in total, distributed across the right compounds, is nearly always a safer and more sustainable path than pushing a single drug to extremes.
Monitoring & Feedback Loops
Using PEDs within a minimum effective dose framework only works if progress and health are tracked continuously. The body adapts quickly, and what looks manageable on paper can shift into dangerous territory in a matter of weeks if monitoring is neglected. Establishing proper feedback loops - both objective and subjective - is the only way to know whether use is genuinely sustainable.
These are the absolute bare minimums and if you cannot afford the time, effort, energy and cost attached to them then you can’t afford to be on cycle.
Bloodwork Essentials
The foundation of monitoring is bloodwork. At an absolute minimum, every athlete should keep an eye on:
Lipids: HDL, LDL, and triglycerides to assess cardiovascular risk.
Haematocrit and haemoglobin: high levels thicken the blood, increasing clotting risk.
Liver enzymes (AST, ALT, ALP, GGT): crucial if oral agents are used.
Kidney markers (creatinine, BUN, eGFR): often overlooked, but essential in long-term users.
Hormones: total and free testosterone, oestrogen, prolactin, and sometimes progesterone for context.
Frequency depends on the intensity of use. For someone running moderate doses, quarterly testing is a baseline standard; for heavier cycles or oral-heavy stacks, monthly testing may be more appropriate.
Supplementation for Health
No supplement can erase the risks of anabolic use, but they can help blunt some of the damage. Liver support compounds like TUDCA and NAC have strong evidence for reducing enzyme elevation, but they are not universally effective, nor do they make reckless oral use safe. Cardiovascular support - omega-3, citrus bergamot, CoQ10 - may help protect lipids and heart health, but again, these are supportive measures, not antidotes. Choosing the right health supplements is highly individual and should ideally be guided by bloodwork and professional oversight.
Cardiovascular Monitoring
Even without labs, simple daily or weekly checks can give valuable insight. Blood pressure is the most practical marker - home cuffs are inexpensive and accurate enough to catch upward trends early. Resting heart rate provides additional feedback on recovery and systemic stress. For athletes with access, periodic ECGs can reveal arrhythmias or early warning signs of heart strain that might otherwise be missed.
Subjective Feedback
Not all feedback comes from tests. PEDs influence mood, sleep quality, libido, and appetite - all of which can indicate whether the body is coping or being pushed too far. A cycle that delivers bigger lifts but leaves the athlete unable to sleep, constantly irritable, or uninterested in food is not a sustainable approach. Keeping a log of subjective changes alongside training data is one of the simplest but most effective harm-reduction tools.
Knowing When to Pull Back
The hardest part of PED use is recognising when to ease off. If blood pressure spikes, lipids crash, or liver enzymes climb, continuing at the same pace is a gamble with long-term health. The same applies to persistent insomnia, emotional volatility, or loss of libido. Pulling back to a lower dose, or cruising at a therapeutic baseline, is not a sign of weakness - it’s how athletes stay in the game for decades instead of burning out in a few years.
Monitoring and feedback loops aren’t an afterthought; they are the safety net that makes the minimum effective dose strategy possible. Without them, the concept collapses into guesswork. With them, athletes can adapt their use in real time and strike a balance between progress and longevity.
Common Pitfalls in PED Use
Even when athletes approach PEDs with some degree of caution, there are recurring mistakes that undermine long-term progress. Understanding these pitfalls is crucial to applying the minimum effective dose principle effectively.
1. The “More Is Better” Mindset
Perhaps the most common trap is assuming that if a moderate dose delivers results, doubling or tripling it will deliver proportionally greater results. This ignores the reality of receptor saturation and diminishing returns. Beyond a certain point, extra milligrams contribute little to performance but dramatically increase the risk of cardiovascular strain, hormonal chaos, and organ damage. The athlete may see short-term improvements, but they pay for them with reduced longevity.
2. Polypharmacy Without Purpose
Another frequent mistake is stacking multiple compounds simply because they are available or popular online. Running six or seven drugs at once without a clear rationale makes it impossible to identify what is actually effective and what is causing side effects. Each additional compound adds complexity, increases the monitoring burden, and raises the risk of dangerous interactions. Effective stacking is about synergy at low doses, not chasing exotic cocktails with no strategic aim.
3. Ignoring Health Markers
Bloodwork, blood pressure, and subjective feedback are often neglected once the athlete starts feeling “good” on cycle. This complacency is dangerous. Many of the most damaging effects of PEDs - arterial plaque, kidney strain, left ventricular hypertrophy - accumulate silently. By the time symptoms appear, damage is already advanced. Consistent monitoring is not optional; it is the only way to know if use remains within manageable limits.
4. Short-Term Gains vs. Long-Term Performance
PEDs are often treated as a way to maximise the next 12 weeks without considering the next 12 years. Chasing rapid size or strength jumps can lead to cycles so harsh that athletes shorten their competitive careers to just a handful of productive seasons. The strongest lifters and longest-lasting bodybuilders are rarely the ones who escalated fastest - they are the ones who treated PEDs as tools to support consistent, compounding training over decades.
5. Failing to Recognise Sex-Based Differences
PED use is not the same for men and women. Female athletes are far more sensitive to androgenic side effects, and the margin between a performance-enhancing dose and a masculinising dose is narrow. Voice deepening, clitoral enlargement, hair growth, and menstrual disruption can appear rapidly and are often irreversible. Applying male-oriented protocols to female athletes is one of the most harmful mistakes coaches or competitors can make. A minimum effective dose approach is especially critical for women, as their effective ranges are dramatically lower and their risk of permanent side effects far higher.
Applying MED to Training Cycles
PEDs are often used as if every block of training demands the same level of support. This is one of the fastest ways to escalate use unnecessarily. Just as training is periodised into phases of building, maintaining, and peaking, PEDs should be periodised to match. The minimum effective dose approach ensures that each compound is introduced only when it serves a clear purpose, and removed once that purpose has been met.
Periodisation of PED Use
Build phases (off-season strength or hypertrophy): The focus is on steady progress. A low to moderate testosterone base is usually sufficient, with no need for aggressive stacking. This phase may last months, with consistent training and nutrition doing most of the work.
Maintenance phases: Between competitions or during lighter training blocks, PED use can often be scaled back to a cruise or replacement level. This keeps health markers in check and preserves the ability to escalate later when needed.
Peak phases (competition prep): Here, PEDs can be strategically layered to maximise strength, aggression, or appearance. The key is timing - higher-risk agents are used sparingly and for the shortest duration possible, not as a constant background.
Discipline-Specific Differences
Strongman & Powerlifting: The main goal is recovery, neural drive, and the ability to express strength under heavy loads. Moderate testosterone with selective additions (nandrolone for joint relief, a short oral for peaking) is often more effective than high doses of multiple compounds.
Bodybuilding: Visual outcomes take priority. Compounds are often chosen for their cosmetic effect - drying out, tightening, or adding fullness. Even here, though, the MED principle applies: the leaner and more conditioned the athlete becomes, the less drug exposure is needed to see visible changes.
Case Study Examples
Off-Season Strength Phase: An athlete runs only a testosterone base at 150–200 mg per week. Training volume is high, nutrition is geared toward growth, and recovery is supported primarily by lifestyle. Gains come steadily without layering multiple compounds.
Peak Block: In the final weeks before a competition, a short oral is introduced at MED ranges to boost training performance and meet-day output. Examples include:
Anadrol added only for the last 2–3 heavy sessions before tapering.
Halotestin on competition day to sharpen aggression and neural drive. The window of use is measured in days or weeks, not months, which limits side effects while still delivering the intended performance boost.
The guiding principle is simple: extra compounds are for very short windows only. They are not background noise in every cycle. If training, recovery, and nutrition are locked in, athletes rarely need more than a base dose of testosterone until the final push before a meet or show.
Safe Needle Use and Injection Practices
If someone chooses to use injectable PEDs, harm reduction begins with proper injection hygiene. Needles and syringes should always be single-use and sterile, never shared under any circumstances due to the risk of bloodborne infections such as HIV and hepatitis. Skin should be cleaned with an alcohol swab before injection, and used needles should be disposed of in a sharps container - not in regular household waste. Rotating injection sites (glutes, quads, delts) helps prevent scar tissue build-up, abscesses, and nerve damage. Oil-based injectables should be administered slowly with an appropriately sized needle (often 23–25 gauge), and aspiration is sometimes used to check for blood return before injection to avoid accidental intravascular administration. Injections should always be intramuscular, never intravenous or subcutaneous unless a compound is specifically designed for that route. Above all, sterile technique and patience in preparation reduce the risk of infections and long-term tissue damage.
Long-Term Considerations
PEDs can change the course of a career, but they also change the body in ways that may last a lifetime. Anyone choosing to use must think beyond the next training block or competition and consider what long-term use will mean for health, fertility, and life after sport.
Cycling, Cruising, and TRT
Historically, athletes would “cycle” - run a block of PEDs, then attempt to restore natural function with post-cycle therapy. In reality, repeated suppression often leaves natural production permanently compromised. Many athletes eventually move to a cruise model, maintaining a low-dose baseline year-round and only escalating briefly to peak. For others, the endpoint is therapeutic testosterone replacement (TRT), whether by necessity or choice. Whichever route is taken, it’s important to understand that PED use is rarely temporary. For most, it becomes an ongoing commitment at some level.
Psychological Impact
Chronic PED use doesn’t just affect the body. It can shape how athletes see themselves and their performance. Coming off a cycle often means lower energy, reduced strength, and a physique that feels smaller or flatter. For some, this creates dependency, anxiety, or identity issues - particularly when progress feels tied to “what’s in the syringe” rather than training or discipline. Recognising these psychological effects and planning for them is as important as managing bloodwork.
Fertility and Health After Competition
PEDs can disrupt fertility, sometimes permanently. Athletes who plan to have children should weigh this risk carefully and consider banking sperm before long-term use. Beyond fertility, the health costs of PED use accumulate over time: cardiovascular strain, kidney function decline, and hormonal imbalances can all persist long after retirement. A plan for post-career recovery - whether that means staying on TRT, undergoing regular medical testing, or focusing on rehabilitation - should be part of the strategy from day one.
Medical Testing and Oversight
Routine check-ups, including cardiac screening, blood pressure monitoring, and comprehensive blood panels, are essential. Left unchecked, silent damage can progress until it becomes irreversible. Even athletes who “feel fine” should assume risk is present and catch issues early through medical oversight.
PEDs Are Not a Substitute
Finally, PEDs are not there to paper over cracks in training, nutrition, or lifestyle. A disorganised program, poor recovery, or inadequate diet cannot be fixed with more milligrams. The strongest athletes are those who build a foundation of consistent training, structured nutrition, quality sleep, and stress management - and then layer PEDs sparingly on top. Without that base, PEDs only magnify the chaos.
Long-term success is not about who can push the hardest in a single season, but who can sustain progress year after year without destroying their health. PEDs can extend that window if used responsibly, or close it early if mismanaged. The difference lies in planning for the long term from the very beginning.
Additional Considerations
While the core principles of Minimum Effective Dose (MED) apply across the board, there are a handful of extra factors that deserve specific mention. These don’t fit neatly into the compound-by-compound breakdown but are critical for athletes who want to think about PEDs responsibly.
Females and PED Use
The consequences of PED use in women are not simply “lighter versions” of what men face. The risk–reward curve is steeper, and virilisation side effects can become permanent even at relatively low doses.
Relatively more tolerable (still not safe): Low-dose Anavar (5–10 mg), Primobolan (25–50 mg/wk), or cautious use of peptides/GH in clinical ranges.
High-risk/no-go: Trenbolone, high-dose testosterone, potent androgens like Anadrol or Superdrol. These carry extreme risk of irreversible voice deepening, clitoral enlargement, and facial hair growth. Harm-reduction take-home: Female athletes often benefit from shorter cycles, lower dosing, and longer off-periods. But no amount of caution eliminates the possibility of permanent change.
Blood Donation & Phlebotomy
One under-discussed consequence of PED use - especially with testosterone, EQ, or long-term androgen exposure - is elevated haematocrit (thickened blood). This increases clotting risk, strains the heart, and can shorten lifespan.
Blood donation or therapeutic phlebotomy is often used by athletes to manage this.
Harm-reduction: This isn’t a substitute for lowering dose, but it is a vital tool for keeping haematocrit in check when levels rise above safe thresholds.
Legal & Supply Risks
Even if you could dial in the “perfect” MED cycle on paper, reality complicates things:
Counterfeit and under/over-dosed products are widespread in the underground market.
GH, Primo, SARMs, and peptides are especially notorious for being mislabelled, spiked, or outright faked.
Legally, possession without prescription can carry real penalties - and contamination/adulteration makes even careful use a gamble. Harm-reduction: The purity of what’s actually in the vial or tab is a risk factor you can’t fully control outside prescription channels.
Post-Career Transition
PEDs don’t exist in a vacuum - there comes a point where athletes move on from competitive sport. Planning ahead matters.
Return to natural baseline: Possible, but not guaranteed - suppression can persist long-term.
TRT for life: Many athletes effectively transition to lifelong testosterone replacement.
Fertility concerns: Preserving fertility may require HCG, FSH, or banking sperm/eggs before long-term use.
Mental shift: Accepting that performance will decline post-PED use can be harder than the physical transition. Harm-reduction: Think about your “exit plan” before you’re forced into one by health issues.
Psychological Risks
PED use doesn’t only affect the body.
Dependency: Cycles can become psychologically addictive - the athlete feels “flat” or “small” without them.
Body dysmorphia: PEDs can reinforce unrealistic self-image standards, leading to a cycle of chasing size or leanness at all costs.
Mood & behaviour changes: Ranging from irritability to more profound anxiety, depression, or paranoia. Harm-reduction: Acknowledge that PEDs don’t just change your physiology - they change how you see yourself. Ignoring the psychological dimension leaves a huge blind spot.
The minimum effective dose approach is not about settling for less or holding back progress. It is about maximising longevity - keeping athletes healthy enough to train hard, recover well, and keep making gains for years rather than burning out after a short burst of reckless use.
PEDs are tools, not shortcuts. When applied with restraint, they can extend a career, enhance recovery, and support consistent development. When abused, they can destroy health, cut competitive years short, and leave lasting damage. The athletes who thrive long-term are rarely the ones who used the most, but the ones who used the least they needed to while keeping training and lifestyle at the centre of their progress.
Harm reduction and continuous education must stay at the heart of this discussion. Every athlete’s body responds differently, and what works safely for one may cause issues for another. That’s why ongoing monitoring, medical oversight, and an honest appraisal of risk are non-negotiable.
And to be clear: nothing in this article should be taken as medical advice. The information presented here is educational, intended to inform better decisions for those who choose to use PEDs. The safest path is always through medical professionals and evidence-based guidance.
The principle remains simple: start low, use only what you need, and keep the long view in mind. Strength is measured in time - and those who can sustain it the longest are the ones who truly win.
I've gone backwards and forwards on including the actual listed dosages below because I genuinely believe it really depends on a lot more factors but lets try and do it in good faith and if not I'll remove them later
Compound-by-Compound Breakdown: Framing and Disclaimers
Before diving into the specifics of individual compounds, it is essential to set the stage clearly. This section is not medical advice. It is not a prescription or a recommendation to use any of these substances. The information provided here is intended strictly for harm reduction and educational purposes. It draws on a combination of published research, clinical evidence where available, and decades of monitored and anecdotal experience within strength sports. The aim is to give athletes and coaches a realistic sense of what constitutes a minimum effective dose (MED), how different drugs work, and where the main risks lie.
PED use has always been a complex intersection of science, practice, and culture. Clinical studies on anabolic-androgenic steroids and related compounds are limited, and when they do exist, they often focus on medical populations rather than athletes. As a result, much of the practical knowledge in this field comes from experienced users, coaches, and physicians working with athletes under close observation. This blending of science and lived experience is not perfect, but it is often the only way to build a picture of what is effective, what is excessive, and what is outright dangerous.
The minimum effective dose concept underpins this breakdown. For each compound, the focus is on the lowest dose range that produces tangible benefits in strength, recovery, physique, or wellbeing, while minimising disruption to health markers. This is not about “optimal” in the bodybuilding forum sense - it is about the smallest intervention that still moves the needle. By staying close to that threshold, athletes can manage side effects more effectively, reduce the need for ancillary drugs, and keep their systems more stable over time.
For each substance covered, the breakdown will include:
Mechanism of Action: How the drug works in the body and what pathways it primarily influences.
Minimum Effective Dose Range: Approximate weekly milligrams (for injectables/orals) or IU (for hormones/peptides).
Primary Benefits: What athletes typically seek from the compound - strength, size, recovery, appearance.
Major Risks: The side effects most associated with the drug, especially at higher doses or during prolonged use.
Notes on Stacking: How it might interact with other agents, and why it may or may not be combined within a MED framework.
It is also important to emphasise that these ranges are approximate, not universal. Genetics, training age, sex, bodyweight, and overall health all change how a person responds to PEDs. A dose that is effective but manageable for one athlete may be excessive for another. That variability is why regular bloodwork and monitoring are non-negotiable - even at so-called “low” doses.
Finally, keep in mind that PEDs do not exist in isolation. The impact of each drug is shaped by the athlete’s nutrition, training quality, recovery practices, and overall lifestyle. A well-structured program and supportive environment make lower doses more effective. A poor foundation only encourages dose escalation, turning what could have been a manageable enhancement into a destructive cycle.
This breakdown is offered not to glorify use, but to help those who have already chosen to use navigate with a clearer understanding of risks and thresholds. Armed with knowledge, athletes can avoid some of the most common and dangerous pitfalls: needlessly high doses, reckless stacking, and ignoring health markers until it is too late.
This is also not even close to an exhaustive list:
A. Testosterone (The Base Compound)
Testosterone is the foundation of nearly all anabolic steroid use. It is the primary male sex hormone, responsible for muscle protein synthesis, libido, energy, and general wellbeing. Even when other anabolic agents are used, testosterone is almost always included at some level to maintain physiological function and prevent the health problems associated with suppression.
Different Esters: How They Differ
Testosterone itself is the same molecule regardless of the ester attached; the ester simply alters how quickly it is absorbed and released into the bloodstream:
Testosterone Propionate: Short-acting; requires frequent injections (every other day or daily). Allows for faster clearance but can cause more injection site irritation.
Testosterone Enanthate / Cypionate: Medium esters, released steadily over ~5–7 days. Typically injected once or twice weekly. These are the most common choices for performance use due to balance of stability and convenience.
Testosterone Decanoate / Undecanoate: Long esters, designed for medical TRT where injections are less frequent (every 2–4 weeks or longer). They can cause hormone fluctuations and are less commonly used in performance settings.
The ester choice does not change the effect of testosterone itself - only the timing of release and how often injections are required.
Role in PED Use
Testosterone serves as the anchor of almost every cycle. It maintains a baseline of androgenic activity, supports physiological functions (libido, mood, energy), and prevents the severe side effects that can arise from running “testosterone-free” cycles. It is the reference point against which other compounds are added.
Minimum Effective Dose (MED)
100–200 mg per week is generally sufficient to move an athlete into the low-supraphysiological range, providing measurable strength, recovery, and physique benefits.
This range overlaps with higher-end TRT protocols but is far below the multi-gram dosing seen in bodybuilding circles.
For many athletes, especially in strength sports, this level of use may be sustainable long term if health markers are monitored closely.
Risks at Higher Doses
As testosterone dose increases, risks scale disproportionately:
Oestrogen-related issues: gynaecomastia, water retention, mood swings.
Blood pressure elevation: driven by fluid retention and vascular strain.
Lipid disruption: HDL suppression, LDL elevation, raising cardiovascular risk.
Haematocrit increase: thicker blood, higher clot risk.
Androgenic effects: acne, hair loss, prostate stress (more pronounced in genetically predisposed athletes).
These risks are relatively modest at MED levels but become far more pronounced at gram-level weekly dosing.
Notes on Stacking
Testosterone provides the base; additional compounds are layered on top only when needed for specific outcomes.
Lowering test slightly and combining with mild anabolics (e.g. Primobolan, Masteron) can often deliver better results than pushing testosterone alone to higher doses.
Because it aromatises (converts to oestrogen), testosterone often dictates whether aromatase inhibitors are needed. With an MED approach, oestrogen management is often minimal or unnecessary.
B. Nandrolone (Deca / NPP)
Nandrolone is one of the longest-standing anabolic steroids in performance sport, valued for its ability to promote muscle growth and enhance joint comfort. Its chemical structure makes it less androgenic than testosterone, but it carries unique risks that must be carefully managed.
Different Esters: How They Differ
Nandrolone Decanoate (Deca-Durabolin): Long-acting ester, releasing steadily over 7–10 days. Typically injected once weekly. Favoured for off-season mass building due to stability and convenience.
Nandrolone Phenylpropionate (NPP): Shorter ester, requiring injections every other day or 2–3x per week. Provides faster onset and easier clearance, making it preferred for athletes who want tighter control or to limit duration of exposure.
The base hormone is identical regardless of ester - only the release profile changes.
Role in PED Use
Nandrolone is often used in combination with testosterone to support tissue growth while lowering the overall androgenic burden. It is well known for providing “joint relief,” reducing inflammation and discomfort in connective tissues, though this effect is subjective and can mask underlying injuries.
Minimum Effective Dose (MED)
100–200 mg per week is generally sufficient to see improvements in recovery, joint comfort, and lean tissue gain.
At these levels, nandrolone can act as a supportive addition rather than a dominating force in a cycle.
Pushing far beyond this range increases both efficacy and risk sharply, often without proportional returns.
Risks and Side Effects
Nandrolone carries specific liabilities distinct from testosterone:
Prolactin-related issues: elevated prolactin can cause erectile dysfunction, reduced libido, and in some cases gynaecomastia.
Neurological impact: some users report mood changes, lethargy, or “deca-dick” at higher doses.
Cardiovascular strain: negative effects on lipids, blood pressure, and long-term heart health.
Androgenic suppression: very suppressive to natural testosterone, making a test base non-negotiable.
Notes on Stacking
Should always be paired with testosterone to maintain physiological function.
Works synergistically with other mild anabolics (e.g. EQ, Primo) when kept at conservative levels.
If prolactin issues arise, dopamine agonists (cabergoline, pramipexole) are sometimes used, but these carry risks of their own. The harm-reduction strategy is to keep the dose modest in the first place.
C. Boldenone (Equipoise / EQ)
Boldenone undecylenate, commonly known as Equipoise (EQ), is a derivative of testosterone with reduced androgenic activity and a reputation for providing steady, moderate gains. Originally developed for veterinary use, it has been adopted by athletes for its long-acting nature and relatively mild profile compared to harsher anabolics.
Specific Considerations
EQ is typically chosen for its ability to promote gradual lean tissue growth, improve recovery, and in some cases stimulate appetite - though this effect is highly individual. Its slow release and extended half-life make it a long-term compound rather than something suited to short bursts or rapid changes.
Minimum Effective Dose (MED)
200–300 mg per week is generally sufficient to deliver the desired effects: slow, consistent gains without major side effects in most users.
Going higher often exaggerates its main drawback - red blood cell (RBC) elevation - without dramatically improving results.
Risks and Side Effects
While EQ is often considered a “mild” anabolic, its risks are unique and must not be underestimated:
Elevated RBC/haematocrit: EQ strongly stimulates erythropoiesis (red blood cell production). This thickens the blood, raising blood pressure and clotting risk. Regular monitoring is essential, and some athletes require therapeutic phlebotomy if levels climb too high.
Blood pressure increases: Often linked to the above effect; cardiovascular monitoring is critical.
Anxiety and restlessness: Many users report heightened anxiety, agitation, or even paranoia at moderate to high doses. This appears to be specific to boldenone and is highly individual.
Long half-life: Because of its undecylenate ester, EQ takes many weeks to build up and just as long to clear. This makes it inflexible for short-term use and harder to manage if side effects appear.
Notes on Stacking
Pairs well with testosterone for long off-season phases where steady growth is the goal.
Works best in cycles of 12+ weeks due to its slow-acting nature; not recommended for short peaks.
Should be avoided in athletes already prone to high haematocrit or cardiovascular strain.
Because of its unique psychological side effects, some lifters find EQ intolerable even at low doses - monitoring subjective response is key.
D. Dianabol, Anadrol, Anavar, and Other Oral AAS
Oral anabolics have been a cornerstone of PED use since the 1960s, prized for their rapid effects on strength, size, and training aggression. They are often used as “kick-starters” in cycles or during short peaking phases to provide results faster than longer-ester injectables. However, their hepatotoxicity and cardiovascular impact make them the most dangerous category of anabolic steroids when abused.
Specific Considerations
Dianabol (Methandrostenolone): Known for rapid size and strength gains, “wet” mass (water retention), and a strong boost in training drive.
Anadrol (Oxymetholone): Extremely powerful for strength, appetite manipulation, and muscle fullness. Can also increase water retention significantly.
Anavar (Oxandrolone): Considered one of the milder orals; valued for cosmetic tightening, strength without bloating, and tolerability in female athletes.
Other Orals (Winstrol, Turinabol, Halotestin): Each has niche uses, typically for physique hardening, aggression, or short-term power output.
Because these compounds are hepatotoxic (C17-alpha alkylated), they place direct stress on the liver. Duration of use should be limited, even at MED ranges.
Minimum Effective Dose (MED)
Dianabol: 10–20 mg/day is sufficient for noticeable increases in strength and training volume.
Anadrol: 25–50 mg/day is enough to push performance; going higher rarely adds more without major side effects.
Anavar: 20–40 mg/day (lower ranges often effective, especially for women).
Winstrol/Turinabol: 20–40 mg/day is typically adequate.
Halotestin: 10–20 mg/day for very short-term aggression and meet-day strength.
These doses provide measurable effects while minimising, though not eliminating, toxicity.
Risks and Side Effects
Liver stress: elevated liver enzymes, cholestasis, and in worst cases, liver failure if abused.
Blood pressure spikes: due to water retention (Dbol, Anadrol) or worsened lipids (all orals).
Appetite disruption: especially with Anadrol, which can make eating enough calories difficult in a mass phase.
Cardiovascular strain: HDL suppression and LDL elevation are pronounced with orals, even at lower doses.
Mood and neurological effects: irritability, anxiety, or lethargy depending on the compound.
Duration of exposure is as important as dose. Even at MED levels, running orals for months at a time compounds risk significantly.
Notes on Stacking
Orals work best in short windows (2–6 weeks) for specific purposes - e.g., strength peaking before competition, or physique hardening during a cut.
They should be layered on top of a testosterone base, not used as standalone cycles.
Health supplementation (e.g., TUDCA, NAC) may support liver health but does not erase hepatotoxicity.
With a MED approach, orals are used sparingly, as finishing touches rather than constant background compounds.
E. Trenbolone
Trenbolone is one of the most infamous anabolic steroids, renowned for its potency and equally notorious for its side effects. Derived from nandrolone, it has strong binding affinity to the androgen receptor, does not aromatise into oestrogen, and exerts dramatic effects on muscle density, strength, and body composition. It is often reserved for advanced athletes because of the difficulty in managing its side-effect profile.
Specific Considerations
Trenbolone is most often used for recomposition - adding lean tissue while stripping fat - or for strength peaking phases where maximum neural drive is required. Unlike other compounds, it has a profound effect on the central nervous system, which can enhance aggression, competitiveness, and training output but also destabilise mood and sleep.
Minimum Effective Dose (MED)
100–200 mg per week is generally enough to see pronounced changes in body composition, strength, and recovery.
Even at these lower ranges, trenbolone exerts effects that many other compounds cannot match.
Escalating far beyond this range typically magnifies side effects rather than providing proportional gains.
Risks and Side Effects
Trenbolone’s risks are wide-ranging and often more severe than other anabolic agents:
Neurological: mood swings, irritability, anxiety, and in some cases paranoia.
Cardiovascular: aggressive impact on lipids, blood pressure, and overall cardiac strain.
Sexual function: increased prolactin levels can cause erectile dysfunction, while at the same time tren often drives extreme libido fluctuations.
Sleep disruption: severe night sweats, insomnia, and restlessness are common even at modest doses.
Kidney strain: though debated, some users report “tren cough” and darkened urine as signs of systemic stress.
The combination of neurological and cardiovascular risk makes tren one of the least forgiving compounds. It can deliver outstanding results but at a steep cost if mishandled.
Notes on Stacking
Trenbolone should always be run with a testosterone base, though often at a slightly reduced test dose to keep side effects manageable.
Works synergistically with compounds like Masteron or Winstrol during cutting phases, or Anadrol/Halo for short-term strength peaks.
Because prolactin can rise, dopamine agonists (e.g., cabergoline) are sometimes employed - but the harm reduction approach is to keep the dose low enough that this isn’t required.
Not recommended for beginners; best reserved for athletes who have already learned how their body responds to more manageable compounds.
F. Primobolan / Masteron
Primobolan (Methenolone) and Masteron (Drostanolone) are both derivatives of dihydrotestosterone (DHT). They are considered “milder” anabolic steroids in terms of side-effect burden, particularly when compared with harsher agents like trenbolone or high-dose testosterone. While their anabolic potency is lower, they have a reputation for improving body composition, enhancing muscle density, and refining appearance without the heavy water retention or aromatisation that often comes with other compounds.
Specific Considerations
Primobolan (Primo): Often regarded as one of the cleanest anabolic agents. Favoured for its ability to provide slow, steady gains in lean tissue with minimal oestrogenic side effects. It is expensive and often counterfeited, but when legitimate, it is one of the safer long-term additions in a MED framework.
Masteron (Mast): Known primarily as a “cosmetic” compound, tightening and hardening the look of the physique. It is often used closer to competition or during lean phases. Like Primo, it does not aromatise into oestrogen and provides a strong anti-oestrogenic effect, making it useful in stacks where oestrogen management is needed.
Both are rarely used as the sole compound but instead layered on top of testosterone for synergy.
Minimum Effective Dose (MED)
200–400 mg per week is generally sufficient for both Primo and Masteron to deliver benefits in appearance, muscle retention, and lean tissue growth.
At these levels, side effects are usually manageable, and the drugs perform their role as supportive rather than dominant agents.
Risks and Side Effects
While considered relatively mild, both compounds still carry androgenic stress, particularly at the higher end of dosing:
Hair loss and acne: due to their DHT-derivative nature, especially in genetically predisposed athletes.
Prostate stress: androgenic load can aggravate prostate health.
Suppression: both are still suppressive to natural testosterone production, making a test base mandatory.
Cost and access (Primobolan): often counterfeited due to its high market value, raising the risk of underdosed or substituted products.
Notes on Stacking
Both compounds are almost always paired with testosterone as a foundation.
Primobolan shines in longer build phases, where its clean profile allows sustained use without wrecking health markers.
Masteron is more often reserved for lean phases or pre-competition use, where its anti-oestrogenic properties and cosmetic effects are most valuable.
In a MED framework, these compounds are best used to refine rather than radically alter progress, keeping total dose lower than if testosterone alone were pushed to higher levels.
G. Growth Hormone (GH)
Growth Hormone (GH), or somatotropin, is a peptide hormone produced naturally by the pituitary gland. In exogenous form, it has become one of the most widely used performance enhancers outside of traditional anabolic steroids. GH is not an anabolic steroid but a completely different class of drug, with distinct mechanisms and risks. It is valued for its ability to improve recovery, support fat loss, and enhance tissue repair.
Specific Considerations
Unlike anabolic steroids, GH does not directly increase muscle protein synthesis. Instead, it stimulates the liver and other tissues to release IGF-1 (insulin-like growth factor 1), which mediates many of its anabolic and metabolic effects. It also promotes fat mobilisation and connective tissue strengthening, making it particularly appealing for athletes seeking longevity and resilience in training.
Minimum Effective Dose (MED)
2–3 IU per day is the typical range for measurable benefits in recovery, joint health, and fat loss.
Doses higher than this (5+ IU/day) are often reserved for bodybuilding preparation or elite athletes, but they carry significantly higher risks.
At MED ranges, many athletes notice improved ability to handle training volume, reduced injury frequency, and gradual improvements in body composition.
Risks and Side Effects
Even at moderate doses, GH carries unique risks that differ from steroids:
Insulin resistance: chronic GH use blunts insulin sensitivity, increasing risk of metabolic issues or type 2 diabetes.
Water retention: bloating, puffiness, and in some cases increased blood pressure.
Carpal tunnel syndrome: nerve compression from tissue swelling is one of the most common complaints, often leading to numbness or tingling in the hands.
Organ growth: prolonged high-dose use has been linked to enlargement of the heart and other organs, raising long-term health concerns.
Cost and access: high-quality GH is expensive; counterfeit or underdosed products are common in underground markets.
Notes on Stacking
GH is often combined with anabolic steroids for synergistic effects - the steroids provide direct muscle-building stimulus, while GH supports connective tissue, fat loss, and recovery.
It can be combined with insulin in advanced protocols, though this raises risks substantially and requires expert-level management.
MED-focused use typically avoids insulin, keeping GH as a standalone support agent rather than a core performance driver.
H. Insulin
Insulin is one of the most powerful hormones in the human body, regulating glucose uptake and storage. While it is life-saving for diabetics, in the PED world it has been used to enhance nutrient partitioning, recovery, and growth - often in combination with Growth Hormone. Its reputation as a “mass builder” is well established, but so are its dangers. Unlike many anabolic steroids, insulin misuse can cause immediate life-threatening consequences.
Specific Considerations
Insulin is valued by some athletes for its synergy with GH and carbohydrate intake, effectively shuttling nutrients into muscle cells and amplifying recovery. In theory, this allows for enhanced glycogen replenishment, muscle fullness, and faster tissue growth. However, the margin for error is incredibly small, and even minor mistakes in timing or dosage can result in catastrophic hypoglycaemia.
Minimum Effective Dose (MED)
Insulin does not lend itself to a true “safe” minimum effective dose outside of medical necessity.
In performance contexts, athletes who choose to experiment sometimes use 2–5 IU peri-workout with carefully measured carbohydrate intake, but even this carries significant risk.
Any use beyond therapeutic necessity should be considered inherently hazardous.
Risks and Side Effects
The risks with insulin are severe and immediate:
Hypoglycaemia: dangerously low blood sugar can lead to confusion, seizures, loss of consciousness, or death.
Dependency: misuse can reduce the body’s natural insulin sensitivity, leading to long-term metabolic issues and higher diabetes risk.
Unpredictable responses: activity levels, carbohydrate timing, and individual variation make outcomes difficult to control.
Long-term metabolic damage: chronic misuse accelerates insulin resistance and fat gain.
Unlike anabolic steroids, where harm often accumulates over years, insulin misuse can be fatal within hours if mismanaged.
Notes on Stacking
Insulin is most often paired with GH, as GH increases insulin resistance and the addition of exogenous insulin can offset this.
In a harm-reduction model, insulin is best avoided entirely unless prescribed for a medical condition.
If it is used, strict oversight, glucose monitoring, and precise nutrient timing are non-negotiable.
I. Ancillaries (AI, SERMs, Caber, Cardarine, Stenabolic, etc.)
Ancillary drugs are often overlooked in discussions of PED use, yet they play a critical role in managing side effects and supporting health. Unlike anabolic steroids or GH, these compounds are not the “primary drivers” of performance, but they can determine whether a cycle is tolerable or unsustainable. Applying the minimum effective dose principle is just as important here: the goal is to use the lowest amount necessary to control side effects without introducing unnecessary risks from overmedication.
Specific Considerations
Aromatase Inhibitors (AIs): Drugs such as anastrozole, letrozole, or exemestane reduce oestrogen conversion from testosterone. They are useful for controlling gynaecomastia and water retention but can crash oestrogen if overused, leading to joint pain, mood issues, and negative effects on lipids.
Selective Oestrogen Receptor Modulators (SERMs): Compounds like tamoxifen or raloxifene block oestrogen at the receptor in specific tissues (e.g., breast tissue) without suppressing it systemically. They are often used to prevent or treat gynaecomastia.
Cabergoline / Pramipexole: Dopamine agonists used to control prolactin levels when using compounds like nandrolone or trenbolone. They are effective but carry neurological risks if overused, including compulsive behaviours and mood instability.
Cardarine (GW-501516): A PPARδ agonist marketed in underground circles as a “non-steroidal endurance enhancer.” While it can improve cardiovascular endurance and fat loss markers, animal studies link it to cancer risk. It is not a safe long-term option.
Stenabolic (SR9009): Another non-steroidal compound touted for fat loss and endurance benefits. Evidence in humans is minimal, and many products are mislabelled or underdosed.
Role in PED Use
Ancillaries are there to support the main agents, not to make up for reckless choices. For example:
An AI may be added if testosterone aromatisation is causing problematic water retention or gyno.
Cabergoline might be used if prolactin rises during nandrolone use.
SERMs can be used protectively without altering systemic oestrogen balance.
But the goal should always be to keep doses of the primary anabolic agents moderate enough that fewer ancillaries are required in the first place.
Minimum Effective Dose (MED)
AI (anastrozole, exemestane): start with the smallest effective dose (e.g., 0.25 mg anastrozole 2x/week) and adjust only if symptoms or bloodwork demand it. We are desperate to avoid AIs just so we are clear.
SERMs (tamoxifen, raloxifene): 10–20 mg/day when indicated.
Cabergoline: 0.25 mg once or twice weekly if prolactin issues arise - not as a default inclusion.
Cardarine/Stenabolic: Not medically approved and not recommended under a harm-reduction model. Their risks often outweigh the potential benefits. Think cancer in rat studies.
Risks and Side Effects
AIs: over-suppression of oestrogen leading to joint pain, low mood, poor cholesterol.
SERMs: vision changes, blood clot risk (rare but documented).
Cabergoline: compulsive behaviour, nausea, psychiatric effects.
Cardarine/Stenabolic: unregulated, research chemicals with uncertain dosing and long-term risks.
Notes on Stacking
Ancillaries should be viewed as safety nets, not cycle staples.
If a cycle demands heavy ancillary use to remain tolerable, the cycle itself is poorly designed.
MED logic applies here as much as it does to testosterone or nandrolone: use the least required to manage side effects, and only when side effects are actually present.
J. Stimulants & Fat Loss Aids
Stimulants are frequently used in strength sports, bodybuilding, and weight-class-based disciplines. While they can enhance fat loss, focus, and training output, they also strain the cardiovascular and nervous systems. In a minimum effective dose framework, the goal is to use the lowest amount needed to achieve an effect without tipping into overstimulation or long-term damage.
Clenbuterol
Specific Considerations Clenbuterol is a β2-adrenergic agonist originally developed as an asthma medication. It increases metabolic rate and stimulates fat loss while also providing a mild performance-enhancing effect through increased oxygen delivery.
Minimum Effective Dose (MED)
20–40 mcg per day is sufficient for most athletes to see fat-loss benefits.
Escalating beyond 80 mcg/day dramatically increases risks without guaranteeing faster results.
Uses
Primarily for fat loss during cutting phases.
Mild improvement in cardiovascular output, though at the cost of greater systemic stress.
Risks
Cardiac hypertrophy and arrhythmia: clen places direct strain on the heart muscle.
Electrolyte imbalance: potassium and taurine depletion can cause cramping, weakness, and irregular heartbeat.
Shakiness, insomnia, and anxiety: common even at low doses.
Risk escalates sharply with dose escalation and long-term use.
Notes on Stacking
Sometimes combined with taurine or potassium supplementation to reduce cramping.
Not suitable for year-round use - best restricted to short cutting windows.
Ephedrine + Caffeine
Specific Considerations The ECA stack (ephedrine, caffeine, aspirin) was once one of the most popular fat-loss aids. Today, aspirin is rarely included, leaving the more common ephedrine + caffeine pairing. Ephedrine is a sympathomimetic that increases thermogenesis and suppresses appetite, while caffeine amplifies its effects.
Minimum Effective Dose (MED)
20–25 mg ephedrine with 200 mg caffeine, up to 2–3x per day.
Higher doses rarely provide more fat loss but greatly magnify side effects.
Uses
Short-term fat loss support.
Appetite suppression.
Increased alertness and training energy.
Risks
Blood pressure spikes and increased heart rate.
CNS overstimulation: jitteriness, anxiety, insomnia.
Urinary retention: common complaint is the sensation of needing to urinate but being unable to.
Dependency: frequent use leads to tolerance, requiring higher doses for the same effect.
Notes on Stacking
Combining with other stimulants (clen, DMAA, pre-workouts) multiplies risk.
Should be cycled to avoid dependency and tolerance.
DMAA (1,3-dimethylamylamine)
Specific Considerations DMAA is a synthetic stimulant once popular in pre-workout supplements. It provides an intense boost in focus, aggression, and perceived energy but has been banned in most countries due to cardiovascular risks.
Minimum Effective Dose (MED)
25–50 mg (when used at all) provides a strong stimulant effect.
Beyond this, side effects escalate quickly, making it a poor choice for sustainable use.
Uses
Pre-training stimulant.
Occasionally used for fat loss in cutting phases.
Risks
Blood pressure elevation and vasoconstriction.
Cardiac strain: arrhythmias, increased heart attack and stroke risk.
Neurological overstimulation: anxiety, headaches, agitation.
Potentially more dangerous when combined with caffeine or other stimulants.
Notes on Stacking
Due to its legal status and high risk profile, DMAA is generally best avoided under harm-reduction principles.
If used, it should never be combined with clen, ephedrine, or high-dose caffeine.
DNP (2,4-Dinitrophenol)
Specific Considerations DNP is one of the most controversial substances ever used for fat loss. Originally developed as an industrial chemical, it uncouples oxidative phosphorylation in mitochondria, effectively making the body waste energy as heat. While this results in rapid fat loss, the margin between an “effective” dose and a lethal dose is extremely narrow.
Minimum Effective Dose (MED)
Often cited around 200 mg per day for fat loss effects.
However, the concept of MED does not truly apply here - even “low” doses carry life-threatening risks.
Risks
Fatal overdose: a small error in dosing, or contaminated product, can result in hyperthermia and death.
Uncontrollable overheating: body temperature rises sharply and cannot be brought down with conventional cooling.
Dehydration and electrolyte loss: leads to cramping, weakness, and potential cardiac failure.
No antidote: once overdose symptoms begin, medical intervention is limited in effectiveness.
Key Point DNP illustrates why not every drug can be adapted into a minimum effective dose framework. The risks are so extreme, and the margin of error so small, that harm reduction here effectively means avoidance.
Peptides & Growth Factors
Peptides have become increasingly popular as alternatives or adjuncts to GH, marketed as ways to stimulate growth, recovery, and fat loss. While some have genuine mechanisms of action, research in athletic populations is limited, and purity is a major concern given their underground supply.
IGF-1 (LR3 / DES)
Specific Considerations Insulin-like Growth Factor 1 (IGF-1) mediates many of the effects of Growth Hormone. Synthetic variants like LR3 (long-acting) and DES (short-acting, site-specific) are used for muscle growth and recovery enhancement.
Minimum Effective Dose (MED)
20–40 mcg pre- or post-training is the typical effective range.
Uses
Enhancing muscle repair and hypertrophy.
Synergistic with GH for tissue growth.
Risks
Hypoglycaemia: especially if combined with insulin.
Organ growth: potential systemic enlargement with long-term use.
Cancer risk speculation: IGF-1 signalling is implicated in tumour growth; while evidence in humans is inconclusive, the risk remains a concern.
GHRP / GHRH Analogues (CJC-1295, Ipamorelin, etc.)
Specific Considerations These peptides mimic natural Growth Hormone releasing hormones or peptides, stimulating the body’s own GH release. They are weaker than direct GH administration but cheaper and sometimes perceived as “safer.”
Minimum Effective Dose (MED)
100–200 mcg 2–3x daily is common for athletes.
Uses
Recovery, sleep quality, fat loss.
May serve as a “budget GH” substitute in some cycles.
Risks
Largely GH-like: water retention, carpal tunnel, insulin resistance.
Less predictable dosing: purity and stability of research peptides can vary drastically.
Note While other peptides such as ibutamoren, semaglutide, tirzepatide, BPC-157, TB-500, etc. are currently popular, this section focuses only on IGF-1 variants and GHRP/GHRH analogues to keep the breakdown concise. Those newer agents carry their own sets of risks and remain poorly researched in athletic settings.
SARMs (Selective Androgen Receptor Modulators)
SARMs were originally developed as experimental drugs to provide the anabolic benefits of steroids without the androgenic side effects. They have been marketed as “safe steroids” or “legal alternatives,” but the reality is far less appealing. Most SARMs remain research chemicals with little to no long-term safety data, and many products sold as SARMs are contaminated, underdosed, or outright substituted with oral steroids.
For athletes, the harm-reduction perspective is straightforward: if you are going to take the plunge into PEDs, SARMs are often the worst of both worlds. They suppress natural testosterone, damage lipids and the liver, and provide weaker anabolic effects than low-dose testosterone - which is usually safer, cheaper, and more predictable.
Ostarine (MK-2866)
Minimum Effective Dose (MED)
5–10 mg per day produces measurable anabolic effects in lean tissue and strength.
Risks
Suppression: reduces natural testosterone production even at low doses.
Lipid damage: lowers HDL, raises LDL, increasing cardiovascular risk.
Liver stress: oral administration still causes hepatotoxicity, despite being marketed as “clean.”
Contamination risk: underground supply frequently substitutes other steroids.
LGD-4033 (Ligandrol), RAD-140, and Other SARMs
Minimum Effective Dose (MED)
Commonly run at 5–15 mg/day depending on compound.
Risks
Suppression: significant shutdown of natural testosterone, often worse than marketed.
Toxicity: liver stress, poor lipid profiles, possible neurotoxicity (RAD-140 especially under scrutiny).
Lack of safety data: almost no long-term human studies exist.
Key Point: Why SARMs Don’t Fit the MED Approach
SARMs do provide anabolic effects, but at the cost of genuine suppression and toxicity.
Their “mild” results are often outweighed by the side effects, especially since they are frequently contaminated or mislabelled.
For most athletes, a conservative dose of real testosterone is safer and more effective than SARMs.
Nootropics / CNS Modulators
While not anabolic agents, certain central nervous system (CNS) stimulants and nootropics are sometimes used in strongman, powerlifting, and other strength sports to enhance alertness, focus, and training drive. Their role is fringe compared to steroids or GH, but they still appear in practice, particularly among athletes with demanding schedules or those looking for an edge in high-pressure environments.
Modafinil / Armodafinil
Minimum Effective Dose (MED)
100–200 mg per day is sufficient for most individuals.
Uses
Promotes wakefulness and reduces fatigue, especially in athletes managing shift work, long travel, or poor sleep patterns.
Sometimes used pre-competition to sharpen focus without the jitteriness of stronger stimulants.
Risks
Sleep disruption: long half-life can make it difficult to wind down at night.
Psychiatric side effects: anxiety, irritability, or mania in sensitive users.
Headaches and dehydration: common, particularly without adequate fluid intake.
Dependence risk: psychological reliance on being “switched on” by a pill rather than lifestyle regulation.
Amphetamines (Prescription ADHD Medications)
Minimum Effective Dose (MED)
5–20 mg Adderall or 10–30 mg Vyvanse are therapeutic prescription levels.
Uses
Increased alertness, focus, and energy.
Can enhance training intent and reduce perceived fatigue during high-intensity work.
Some lifters use them situationally (competition day, heavy sessions).
Risks
Cardiac strain: increased heart rate, blood pressure, and potential arrhythmia.
Dependency and tolerance: rapid escalation of use possible if unsupervised.
Appetite suppression: interferes with caloric intake, potentially limiting growth and recovery.
Sleep disruption and mood swings: can impair long-term training consistency.
Key Point
Nootropics and prescription stimulants can sharpen focus and drive, but they do not build strength or size directly. In the MED framework, they are situational tools at most - not foundations of performance. Relying on them chronically undermines recovery and can introduce cardiovascular and psychological risks that outweigh any short-term training benefit.
Recovery & Health Support Adjuncts
Not every drug used in performance settings is there to build muscle or strength directly. Some are included specifically to offset the health risks that come with PED use - protecting blood pressure, lipids, or glucose management. These compounds do not eliminate risk, but they can help athletes maintain healthier bloodwork and extend their competitive lifespan when used responsibly.
Metformin
Minimum Effective Dose (MED)
500–1000 mg per day, typically split into two doses.
Uses
Improves insulin sensitivity and glucose management.
Often used alongside Growth Hormone or insulin to blunt the insulin resistance those compounds can create.
May offer secondary benefits in body composition control and longevity markers.
Risks
Gastrointestinal issues: nausea, diarrhoea, bloating are common at higher doses.
Potential mitochondrial effects: debated, but some evidence suggests long-term metformin use may blunt adaptations in high-level athletes.
Vitamin B12 depletion: requires monitoring with prolonged use.
Telmisartan (Angiotensin II Receptor Blocker / ARB)
Minimum Effective Dose (MED)
20–40 mg per day.
Uses
Controls blood pressure - one of the most important harm reduction steps for PED users.
Improves lipid profile and has been studied for fat oxidation and recomposition benefits.
May reduce left ventricular hypertrophy, making it particularly valuable for athletes at cardiovascular risk.
Risks
Generally well tolerated, though dizziness, fatigue, or GI upset can occur.
As with any BP medication, dosing and oversight should be handled carefully to avoid excessive drops in pressure.
Deeper Dive: Scientific Clarifications & Nuance
The broad strokes of this guide reflect the best available blend of science, athlete experience, and harm-reduction practice. But a few points deserve extra nuance so readers don’t walk away with misunderstandings or oversimplifications:
Trenbolone and Kidney Toxicity
It’s common to hear that “tren kills kidneys”. In reality, trenbolone does not appear to directly cause renal necrosis. The bigger problem is indirect stress: tren elevates blood pressure, haematocrit, and cardiovascular strain, which all increase renal workload over time. Dark urine often seen on tren is more related to metabolites (increased excretion) than outright kidney failure. Harm-reduction note: tren can still compromise kidney health long-term, but the mechanism is indirect rather than toxic in the same way orals hit the liver.
EQ and Appetite
Equipoise is often described as an “appetite booster,” but in practice, responses vary. Some athletes do indeed eat more easily on EQ; others report crushing anxiety, which flattens appetite instead. Harm-reduction note: appetite effects should be treated as individual variability - never guaranteed. Monitor both food intake and psychological state closely when EQ is in the mix.
Insulin and the Myth of a “Safe MED”
You’ll often see bodybuilders talk about “just a few IU of insulin” as if that makes it manageable. The reality is that insulin is categorically different from AAS: even 2 IU, if mistimed or mismanaged, can be fatal. Yes, therapeutic ranges exist, but this is one compound where “minimum effective dose” does not automatically translate into safety. The margin for error is razor-thin.
Orals - Anavar & Liver Stress
Anavar is frequently marketed as a “mild” oral. Compared to Anadrol or Dianabol, that’s true - but “mild ≠ safe.” Anavar is still 17α-alkylated and hepatotoxic, and long-term use at even moderate doses can elevate liver enzymes and compromise lipid health. Harm-reduction note: don’t let Anavar’s reputation fool you into thinking it’s free of consequences.
Growth Hormone and Organ Growth
GH’s reputation for causing “organ growth” (organomegaly) is based largely on prolonged high-dose abuse (10+ IU daily for years). At MED ranges (2–3 IU), these risks are far lower. Harm-reduction note: while MED use is not risk-free, clarity matters - organ enlargement is primarily a long-term, supra-physiological dose issue.
SARMs
The risks of SARMs go beyond suppression and toxicity:
They are banned in tested sport, and many anti-doping positives come not from intentional use but supplement contamination.
Supply chains are notoriously dirty - products marketed as SARMs often contain prohormones or other AAS instead. Harm-reduction note: if the question is “SARMs or low-dose test,” the latter is both more predictable and, paradoxically, often safer.
Ancillaries - Aromatase Inhibitors (AIs)
Aromatase inhibitors can be life-saving in cases of severe oestrogen issues, but they should not be used prophylactically. Chronic AI use worsens lipid profiles, joint health, and overall cardiovascular risk. Harm-reduction note: the goal is to manage oestrogen through dose control and smart stacking, using AIs only as a last resort, not as a first line of defence.
Other Adjuncts Worth Noting
Statins: can be used to manage cholesterol profiles if PEDs are crashing HDL and raising LDL.
Baby Aspirin (low-dose): sometimes used as a preventative for clotting risk, particularly when haematocrit is elevated - but carries bleeding risk if misused.
Omega-3 supplements (fish oil, krill oil): support lipid health, reduce systemic inflammation, and promote cardiovascular protection.

Final Note
This is not an exhaustive list - it’s simply what could be assembled in a short brainstorm. There are countless other compounds and strategies athletes may use to manage side effects, from antioxidants to blood donation for haematocrit control. The critical point is that PED use without health support is reckless. These adjuncts are not optional luxuries; they are often the difference between manageable long-term use and serious complications.
Before closing, it is worth repeating as plainly as possible: nothing in this article is medical advice. This material is presented for educational and harm-reduction purposes only, to provide context for how these substances are commonly discussed and misused within strength sports. It is not an encouragement, endorsement, or recommendation to use anabolic steroids, growth hormone, stimulants, or any other performance-enhancing drugs.
The reality is that outside of a medical prescription, the use of these drugs is both illegal and unsafe. Laws vary from country to country, but in almost all cases possession, use, or distribution of anabolic steroids and other PEDs without a prescription is prohibited. Legally and medically, the only safe approach is to avoid these substances entirely unless they are prescribed by a qualified healthcare professional for a legitimate medical need.
The minimum effective dose framework discussed here is not a “safe” way to use PEDs - there is no truly safe way. It is a harm-reduction concept only, aimed at helping those who might already be exposed to these substances make more informed decisions and avoid the worst mistakes. Every compound discussed carries risks that cannot be eliminated, and some (such as DNP) are so dangerous that no dose can be considered acceptable under a harm-reduction lens.
If you are struggling with performance pressure, body image concerns, or the temptation to self-medicate with PEDs, the most effective long-term decision you can make is to invest in training, nutrition, sleep, and recovery - and seek guidance from qualified professionals rather than underground sources.
At the end of the day, strength and success in sport are built on consistency, patience, and health. PEDs are not shortcuts - they are high-risk tools that can cut careers short and leave lifelong consequences. Legally, ethically, and medically, if it is not prescribed to you, you should not be using it.
