LGD-3303 vs S23
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| LGD-3303 | S23 | |
|---|---|---|
| Evidence | Animal only | Animal only |
| Class | SARM | SARM |
| Summary | 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. | 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. |

LGD-3303
LGD-3303 is a nonsteroidal selective androgen receptor modulator — a SARM, and importantly a small molecule rather than a peptide. It comes from the same Ligand Pharmaceuticals program as LGD-4033 (ligandrol), but it is a separate compound and should not be confused with it. The only real evidence…
S23
S23 is a synthetic selective androgen receptor modulator (SARM) — explicitly not a peptide — that binds the androgen receptor and acts as a tissue-selective agonist, aiming for anabolic effects in muscle and bone with relatively less prostate/seminal activity. It was designed as a male…
