ACP-105 Reference

Plain English

What it is

ACP-105 is a SARM, which is a lab-made drug built to act on the same muscle and bone hormone signals that testosterone uses, but in a more targeted way. It is sold only as a research chemical, not as an approved medicine, and no health agency has cleared it for people to take.

What people use it for

It is a lesser-known compound, so use is uncommon. In the bodybuilding and body-recomposition crowd, a few people try it hoping for extra muscle, bone, or brain-protecting effects. None of these are approved uses, and the claims rest on personal stories rather than proof.

What the science shows

The published science is very thin and comes almost entirely from animals, mainly a rodent study where it protected movement function after radiation, plus reported bone-density signals. There is no human clinical program. Much of the other published work on it is just lab methods for spotting it in drug tests.

The catch

The FDA warns the public against SARMs, which are sold illegally and are often mislabeled as research chemicals or supplements. WADA bans them in sport at all times as anabolic agents under class S1.2. Reported risks of SARMs include lowered natural testosterone, liver strain, and cholesterol and heart effects, with some life-threatening reports of heart attack and stroke, and the long-term effects are unknown.

Reference summary

Very thin literature; primarily preclinical neuroprotection and bone-density signal in rodent models.
