Isotretinoin
Also known as: Accutane, Roaccutane, 13-cis-Retinoic Acid, Claravis, Absorica
Lower numbers = closer to natural. Higher numbers = more enhanced.
Why this rating?
Isotretinoin is a prescription retinoid (vitamin A derivative) for severe acne, including the androgen-driven acne that high-dose steroids, especially strongly androgenic compounds, provoke. It is not a performance enhancer; it is a support/cosmetic medication with genuinely serious side effects (teratogenicity, lipid and liver changes, mood concerns). Not WADA prohibited. It does not build muscle, burn fat, or raise anabolic hormones by any path, so it is rated 1, basically natty, no effect on the muscular/physique/performance scale.
Overview
The most powerful acne drug available: an oral retinoid (13-cis-retinoic acid) that can produce long-term or permanent acne remission. In the PED context it is used for the severe acne that high androgen loads cause, particularly from strongly androgenic and DHT-derived compounds that overdrive the sebaceous glands. It is extremely effective, but it carries serious risks (severe birth defects, lipid and liver changes, mucocutaneous dryness, and debated mood effects) and demands monitoring.
Important Warnings
- •Extreme teratogen: must NOT be used by anyone who is or could become pregnant; severe birth defects occur even with brief exposure. Two forms of contraception and pregnancy testing are mandatory (iPLEDGE).
- •Do NOT take vitamin A supplements with it, additive hypervitaminosis-A toxicity.
- •Do NOT combine with tetracycline-class antibiotics (doxycycline, minocycline), risk of raised intracranial pressure (pseudotumor cerebri).
- •Raises triglycerides/cholesterol and liver enzymes, additive with harsh oral steroids and alcohol; requires monthly bloodwork.
- •Mood changes/depression have been reported, monitor and seek help if mood worsens.
- •Impairs wound healing: avoid tattoos, waxing, and cosmetic/laser procedures during and for months after.
- •Do not donate blood during treatment or for 1 month after (recipient could be pregnant).
Purpose & Use Cases
Androgen-Induced / Steroid Acne
The main PED use. Strongly androgenic and DHT-derivative compounds overdrive sebaceous glands, producing severe, often nodulocystic acne (classically back/shoulder 'bacne'); isotretinoin is the definitive treatment when topicals and antibiotics fail.
Severe Nodulocystic Acne
FDA-approved for severe, scarring, treatment-resistant acne, the standard indication.
Scarring Prevention
By clearing severe cystic acne it prevents the permanent scarring that untreated androgen-driven acne can leave.
Benefits
- The most effective acne treatment: clears severe/cystic acne where other therapies fail
- Can produce long-term or permanent remission (not just suppression)
- Directly addresses androgen-driven sebum overproduction
- Prevents permanent scarring from severe acne
- Well-established protocols and monitoring
Good to Know
The nuclear option for steroid acne
Isotretinoin (Accutane) shrinks sebaceous glands and is the most effective treatment for the severe androgen-driven acne that strong steroids (trenbolone, anadrol, high test) can cause. It works when nothing topical does.
The side-effect profile is serious
It is strongly teratogenic (an absolute no in pregnancy), worsens lipids, can strain the liver, dries skin/eyes/lips, and carries mood/depression warnings. It also stacks its lipid hit on top of steroids that are already crushing cholesterol.
Bloodwork is mandatory
Because it compounds the cholesterol and liver strain a cycle already causes, run lipids and liver panels while on it, and be honest about any mood changes.
Dosage Guidelines
| Experience Level | Dosage Range |
|---|---|
| Beginner | 10 – 20 mg/day |
| Intermediate | 20 – 40 mg/day |
| Advanced | 40 – 80 mg/day |
Standard dermatology dosing is ~0.5-1 mg/kg/day to a cumulative target of ~120-150 mg/kg over 15-20+ weeks (the cumulative dose, not the daily dose, predicts durable remission). Many in the PED community use low-dose protocols (e.g. 10-20 mg/day) for steroid acne, trading a slower response for far milder dryness/side effects. Always taken with dietary fat. This is a prescription drug requiring bloodwork (lipids, liver) and, for anyone who can become pregnant, strict pregnancy prevention. It should be run under medical supervision, not self-dosed blindly.
The active metabolite 4-oxo-isotretinoin is longer-lived, with a half-life of roughly 24-29 hours.
Side Effects
Teratogenicity (Birth Defects)
commonIsotretinoin is one of the most potent human teratogens known; exposure in pregnancy causes severe birth defects (CNS, cardiac, craniofacial) and pregnancy loss. This is the single most serious risk, hence the iPLEDGE program.
Absolute contraindication in pregnancy. Anyone who can become pregnant must use two reliable forms of contraception and undergo pregnancy testing; do not share; do not become pregnant during or for 1 month after.
Mucocutaneous Dryness
very commonNear-universal: dry, chapped lips, dry skin, dry eyes, nosebleeds. Dose-dependent.
Lip balm, moisturiser, eye drops, humidifier; lower-dose protocols reduce it.
Elevated Blood Lipids
commonRaises triglycerides and cholesterol (and lowers HDL), compounding the lipid damage many oral steroids and AIs already cause. Marked triglyceride rises risk pancreatitis.
Monthly lipid panels; limit alcohol; omega-3s; do not stack casually on top of harsh orals without monitoring.
Elevated Liver Enzymes
commonTransaminase elevations (liver stress). Additive with hepatotoxic oral 17-alkylated steroids and alcohol.
Monthly liver panels; avoid alcohol and stacking with hepatotoxic orals; stop if enzymes climb significantly.
Muscle / Joint Aches & CK Elevation
commonMyalgia, arthralgia, and elevated creatine kinase, accentuated by intense resistance training, and directly relevant to lifters.
Moderate training intensity if symptomatic; note CK elevation can confuse bloodwork; stay hydrated.
Mood Changes / Depression
uncommonDepression, mood changes, and (rarely) suicidal ideation have been reported. Causality remains debated, but the association is taken seriously and monitored.
Monitor mood; involve those around you; stop and seek help if mood deteriorates.
Impaired Wound Healing / Night Vision
uncommonReduced/delayed wound healing (avoid cosmetic procedures, waxing, laser) and reduced night vision.
Defer elective skin procedures until well after finishing; caution with night driving.
General Mitigation Strategies
This is a serious drug that should be run with a prescriber and monthly bloodwork (lipids and liver at minimum). The lipid and liver strain is the key overlap with PED use. Do not layer it on top of harsh oral steroids and alcohol without monitoring. Pregnancy prevention is non-negotiable. Do NOT take any vitamin A supplements alongside it (additive toxicity) and do NOT combine with tetracycline antibiotics (raised intracranial pressure risk). Low-dose protocols meaningfully reduce the dryness and side-effect burden.
Post Cycle Therapy (PCT)
Not hormonal. No PCT required: but note the isotretinoin course typically outlasts the steroid cycle, and its lipid/liver effects persist while it is being taken.
How It Works
Isotretinoin targets all four drivers of acne. It dramatically shrinks the sebaceous glands and cuts sebum output (the key effect, acne bacteria and clogging depend on sebum), normalises the abnormal keratinisation that plugs follicles, is anti-inflammatory, and indirectly reduces Cutibacterium acnes by removing its oily habitat. Uniquely among acne treatments it can induce durable remission rather than merely suppressing acne while taken. Because sebaceous glands are androgen-driven, this is precisely why high-androgen cycles trigger the acne it treats.
