LGD-3303 vs Ligandrol
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| LGD-3303 | Ligandrol | |
|---|---|---|
| Evidence | 3/10 | 7/10 |
| Class | SARM | SARM |
| Summary | LGD-3303 is a nonsteroidal selective androgen receptor modulator (SARM), not a peptide. Its evidence is preclinical (rodent and equine) only — there are no human trials. It is an unapproved research chemical and is banned at all times in sport. | 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. |

LGD-3303
LGD-3303 is a SARM — a selective androgen receptor modulator (a lab-made molecule that switches on the body's androgen, or male-hormone, receptors in some tissues but not others). It is not a peptide, and it is not a steroid. It came out of the same Ligand Pharmaceuticals research program as…
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…
