AC-262356 Reference

Plain English

What it is

AC-262356 (also written AC-262536) is a SARM, which is a lab-made drug built to switch on the body's muscle-building hormone signals while trying to leave other tissues alone. It is sold only as a research chemical, not as an approved medicine, and no health agency has cleared it for use in people.

What people use it for

In the bodybuilding and fitness world, SARMs like this are taken in hopes of building muscle and dropping fat at the same time, a goal often called a recomp. That use is anecdotal and is not an approved use, and for AC-262356 specifically it is rare and experimental because there is almost nothing published to learn from.

What the science shows

The evidence is early and animal-only. The main study tested it in rats and found it boosted muscle markers while having weaker effects on the prostate, but it never had a human clinical program, so its real effects and safety in people are unknown.

The catch

The FDA warns the public against SARMs, which are not approved, are sold illegally, and are often mislabeled, and WADA bans SARMs in sport at all times as S1.2 anabolic agents. Reported SARM risks include lower natural testosterone, liver strain, and effects on cholesterol and the heart, and the long-term effects are simply not known.

Reference summary

Preclinical-only literature; primarily rodent prostate and bone-density tissue-selectivity studies.
