Ostarine (MK-2866) also known as Enobosarm is a quite well-researched relatively mild yet very selective molecule that enhances male sex hormone effects that help to build muscle and strenghten joints and bones. Due to its mild nature and high selectivity, it is suitable for women; in men, it nearly does not suppress endogenous testosterone production. In addition, it’s side effects have appeared none or minimal, comparable to that of placebo. In the many clinical studies, 3 mg dose has yielded positive results without suppression of endogenous male sex hormone, and thus that dose appears the most reasonable dose. It is considered as a doping substance, and as such, it seems to be quite popular (in higher doses ranging from 10 to 35 mg that neccessitate post-cycle treatment), perhaps due to its relatively long history. Its effects include:
- Increased muscle mass and strength
- Reduced fat mass
- Most likely, improvement of bone strength
