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

Andarine
Andarine (S4) is a selective androgen receptor modulator (SARM), a synthetic small molecule — not a peptide and not an anabolic steroid. It is frequently sold in fitness, biohacking, and "research chemical" channels as a muscle-building "safer steroid alternative," but its real evidence base is…
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…
