Ligandrol vs Ostarine
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| Ligandrol | Ostarine | |
|---|---|---|
| Evidence | 7/10 | 7/10 |
| 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 SARM (selective androgen receptor modulator — a drug that turns on the same cell switch as testosterone, but only in some tissues). Importantly, it is a small lab-made molecule, not a peptide. It is sold widely online and is popular in fitness circles, where it is pitched…
Ostarine
Ostarine (also called MK-2866 or enobosarm) is a selective androgen receptor modulator (a compound designed to act like a muscle-building hormone in some tissues but not others). It is often — and wrongly — sold online as a "safer steroid alternative" for building muscle. It is not a peptide, and…
