A recent study has shown that YK11, a selective androgen receptor myostatin inhibitor, accelerates the expression of Follistatin in mice.
Follistatin is a myostatin and activin-binding protein naturally found in the human body and has been used as a treatment for several degenerative muscle diseases. When follistatin levels are raised, myostatin levels will be inhibited. Inhibition of myostatin results in increased muscle mass and improved strength.
This study revealed that mice with low levels of myostatin have twice the amount of muscle mass compared to mice with high levels of myostatin. This shows the massive potential research implications of the strong anabolic effects that YK-11 can possess
