MYO-YK (YK-11) by Hardcore Series is one of the most advanced SARMs on the market. Why? Because it is not only a SARM, but it also works as a Myostatin Inhibitor. It is considered the most advanced muscle builder of the entire range as well as creating dramatic increases in strength and power.

YK-11 works by binding to androgen receptors selectively. It shows anabolic activity in both the bones and muscles. Since it is also a Myostatin Inhibitor, it increases follistatin. Follistatin is a naturally occurring protein that suppresses Myostatin, which prevents muscles from getting too large. Allowing more follistatin, in turn can turn off the "limits" on how much muscle your body can build. Currently, there are no other SARMs that work as a Myostatin Inhibitor.
