Follistatin

THE MYOSTATIN BLOCKER

Follistatin is a naturally occurring protein that blocks myostatin and activin, two signals that limit muscle growth. By neutralizing these brakes, follistatin allows muscles to grow larger and stronger. It's also shown promise for hair regrowth and may help reduce fibrosis in organs like the liver.
