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

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…
Testolone
Testolone (RAD-140) is a selective androgen receptor modulator (SARM) — a non-steroidal small molecule, not a peptide and not an anabolic steroid. It was developed as an investigational drug, never approved for any use, and is widely sold online for muscle building despite the complete absence of…
