Overview

Enobosarm, also known as ostarine or MK-2866, is the most studied SARM. It reached phase III trials for cancer-related muscle loss but was not approved.

How it works

Ostarine activates androgen receptors in muscle and bone. Trials showed increases in lean body mass with some reduction in HDL and testosterone.

There is no approved dose. Clinical trials in cancer cachexia used 1 or 3 mg a day.
