A study has shown that YK11, a selective androgen receptor myostatin inhibitor, can increase the expression of follistatin in mice. Follistatin is a protein that naturally occurs in the human body and helps to inhibit myostatin. When follistatin levels are raised, myostatin levels will be inhibited, leading to increased muscle mass and improved strength.
