Ligandrol vs Ostarine
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| Ligandrol | Ostarine | |
|---|---|---|
| Evidence | Preliminary human | Preliminary human |
| Class | SARM | SARM |
| Summary | Ligandrol (LGD-4033) is a nonsteroidal selective androgen receptor modulator (SARM), not a peptide. Its only real human data is a single 3-week Phase 1 trial; it is an unapproved drug, illegal to sell as a supplement, and banned in sport. | Ostarine is an investigational selective androgen receptor modulator (SARM) — not a peptide — with real but limited human evidence for lean-mass effects, no regulatory approval anywhere, and documented liver-injury and hormone-suppression signals. |

Ligandrol
Ligandrol (LGD-4033) is a nonsteroidal selective androgen receptor modulator — a SARM, and importantly a small molecule rather than a peptide. It is widely sold online and used in fitness circles as a supposedly "safer" alternative to anabolic steroids, but the actual human evidence is limited to…
Ostarine
Ostarine (MK-2866 / enobosarm) is a selective androgen receptor modulator that is frequently — and incorrectly — sold on the gray market as a "safer steroid alternative" for muscle building. It is not a peptide and not a dietary-supplement ingredient. There is genuine human evidence that it raises…
