Ligandrol vs S23
Both are sarm compounds. Here's how they line up on the evidence — graded the same way.
| Ligandrol | S23 | |
|---|---|---|
| Evidence | 7/10 | 3/10 |
| 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. | 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 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…
S23
S23 is a lab-made drug in a family called SARMs (selective androgen receptor modulators — molecules that switch on the same cell "docking points" as testosterone, but only in certain tissues). It is not a peptide. The idea behind it was to build up muscle and bone while having relatively little…
