Ligandrol vs S23
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| Ligandrol | S23 | |
|---|---|---|
| Evidence | Preliminary human | Animal only |
| 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. | 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. |

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…
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…
