- 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 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.
- 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.
- 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.
- Animal only Stenabolic (SR9009) SR9009 is a synthetic REV-ERB agonist (not a peptide, not a SARM) with intriguing mouse metabolic data but no credible human evidence, poor oral bioavailability, and documented off-target activity. Unapproved drug, banned in sport at all times.
- 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.
