Tagged androgen.
- Animal only Andarine (S4) A non-steroidal SARM with tissue-selective anabolic activity in rodents, but no completed human efficacy trials; clinical development was halted over vision side effects.
- Animal only Boldenone (Equipoise) Boldenone is an injectable anabolic-androgenic steroid (a synthetic derivative of testosterone), not a peptide. Its only sanctioned use today is veterinary; there is no modern human clinical evidence supporting its physique or performance claims.
- Preliminary human Drostanolone (Masteron) Drostanolone is an injectable, DHT-derived anabolic-androgenic steroid once approved as a palliative breast-cancer drug. Its bodybuilding reputation for 'hardening' and 'dryness' has no controlled human evidence, and it carries the full androgen-class risk profile.
- Preliminary human Fluoxymesterone (Halotestin) Fluoxymesterone is an oral 17α-alkylated anabolic-androgenic steroid (not a peptide), once FDA-approved for hypogonadism and breast-cancer palliation but now largely obsolete. Its strongest, best-documented human data concern liver injury rather than benefit, and non-medical use is illegal and banned in sport.
- Strong human HCG (Human Chorionic Gonadotropin) HCG is a glycoprotein gonadotropin that mimics luteinizing hormone, with strong human evidence for fertility and hypogonadism uses and a formal FDA disclaimer against the discredited 'hCG diet' for weight loss.
- Animal only LGD-3303 LGD-3303 is a nonsteroidal selective androgen receptor modulator (SARM), not a peptide. Its evidence is preclinical (rodent) only — there are no human trials. It is an unapproved research chemical and is banned at all times in sport.
- Preliminary human Ligandrol (LGD-4033) Ligandrol (LGD-4033) is a nonsteroidal selective androgen receptor modulator (SARM), not a peptide. Its only real human data is a single 3-week Phase 1 trial; it is an unapproved drug, illegal to sell as a supplement, and banned in sport.
- No credible evidence Mesterolone (Proviron) Mesterolone is an oral, DHT-derived anabolic-androgenic steroid once sold abroad for male hypogonadism and idiopathic infertility. Controlled human trials for its two historic uses (fertility, mood) are negative or unconvincing, and its performance 'anti-estrogen' reputation has no strong human evidence.
- Strong human Methandrostenolone (Dianabol) An oral 17α-alkylated anabolic-androgenic steroid (not a peptide) with real but modest controlled-trial evidence for gains in body weight and lean mass; it is a Schedule III controlled substance with no current US medical use and well-documented liver, cardiovascular, and hormonal harms.
- Animal only Methasterone (Superdrol) Methasterone is an oral 17α-alkylated anabolic-androgenic steroid (a 17α-methyl version of drostanolone), never an approved medicine; its only robust human evidence is harm — severe cholestatic liver injury — not efficacy.
- Preliminary human Methenolone (Primobolan) A DHT-derived anabolic-androgenic steroid once used medically for bone-marrow-failure anemias and historically studied in breast cancer; its 'mild and safe' bodybuilding reputation rests on lore, not controlled performance trials.
- Strong human Nandrolone (Deca-Durabolin) Nandrolone is an injectable anabolic-androgenic steroid (not a peptide) with high-quality trial evidence that it builds lean mass in catabolic illness, but weaker evidence for strength or functional gains and real androgenic, hormonal, and cardiovascular risks.
- Preliminary human Ostarine (MK-2866) Ostarine is an investigational selective androgen receptor modulator (SARM) — not a peptide — with real but limited human evidence for lean-mass effects, no regulatory approval anywhere, and documented liver-injury and hormone-suppression signals.
- Strong human Oxandrolone (Anavar) Oxandrolone is an oral anabolic-androgenic steroid with genuine clinical trial support in catabolic illness (severe burns, HIV wasting, Turner syndrome), but its 'mild and safe' reputation is marketing, not evidence.
- Strong human Oxymetholone (Anadrol) Oxymetholone is a potent oral anabolic-androgenic steroid (not a peptide) with genuine controlled-trial support in wasting illness, but it carries serious, well-documented liver, lipid, and hormonal risks.
- Animal only Testolone (RAD-140) An investigational, non-approved selective androgen receptor modulator (SARM) with no published human efficacy evidence for fitness use, a documented serious liver-injury case, and prohibited status in sport.
- Animal only S23 S23 is a synthetic selective androgen receptor modulator (SARM) — not a peptide — studied only in rodents as a male contraceptive candidate. There are no human trials, and it is an unapproved drug banned in sport.
- Preliminary human Stanozolol (Winstrol) Stanozolol is an oral/injectable anabolic-androgenic steroid with a famous doping history; its physique reputation rests on weak evidence, while its harmful effects on lipids and the liver are robustly documented.
- Strong human Testosterone Testosterone is the principal human androgen and the prototypical anabolic-androgenic steroid (AAS) — not a peptide — with strong, reproducible human evidence for dose-dependent muscle and strength gains, FDA approval only for confirmed hypogonadism, Schedule III control, and real cardiovascular, hematologic, and hormonal safety signals.
- Animal only Trenbolone Trenbolone is a potent injectable anabolic-androgenic steroid — never a peptide — with no human efficacy trials, an FDA-approved use only as a cattle growth-promoting implant, and serious androgenic, cardiovascular, and hormonal risks.
- Animal only Turinabol (Oral Turinabol) Turinabol is an orally active 17α-alkylated anabolic-androgenic steroid — the signature drug of East Germany's state doping program — with no modern controlled human efficacy trials and the full risk profile of an oral AAS.
- Animal only YK-11 YK-11 is a synthetic steroidal SARM marketed for muscle growth, but its claimed human benefits rest entirely on cell-culture data — there are no human trials, and it is an unapproved drug banned in sport.
