Andarine vs S23
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| Andarine | S23 | |
|---|---|---|
| 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. | 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. |

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…
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…
