| Andarine | LGD-3303 | |
|---|---|---|
| Evidence | 3/10 | 3/10 |
| Class | SARM | SARM |
| Summary | 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. | LGD-3303 is a nonsteroidal selective androgen receptor modulator (SARM), not a peptide.

Andarine
Andarine (S4) is a SARM — a selective androgen receptor modulator (a lab-made molecule designed to act on the body's testosterone-sensing system in a targeted way). It is a synthetic small molecule, not a peptide and not an anabolic steroid. You will often see it sold in fitness, biohacking, and…
LGD-3303
LGD-3303 is a SARM — a selective androgen receptor modulator (a lab-made molecule that switches on the body's androgen, or male-hormone, receptors in some tissues but not others). It is not a peptide, and it is not a steroid. It came out of the same Ligand Pharmaceuticals research program as…
