Description

Ostarine is currently a popular compound among bodybuilders and athletes looking to cut. It was initially created to help fight muscle wasting diseases, but more extensive research is needed to determine its efficacy in preserving lean muscle tissue during a caloric deficit. A recent study found that MK–677 improved growth hormone secretion and markedly increased fat free mass over a 12–month period.
