Follistatin-344 significantly increased muscle growth and strength by blocking myostatin (GDF-8 - a protein that inhibit growth of muscle mass). Follistatin-344 is a promising inhibitor of myostatin, with sufficiently safe profile.
Follistatin-344 is also the perfect choice for athletes who are no longer able to exercise regularly, or those who quit sports, but still want to stay in shape, with massive muscles. It has been shown that the smaller the load of muscles and less physical activity, the higher the concentration subsequently myostatin.
Follistatin (also known as activin-binding protein) is an autocrine glycoprotein encoded FST gene which is produced in almost all tissues. Its primary function in the body is bioneutralization members of the TGF-β family of proteins, with special focus on activin and paracrine hormones. Follistatin is a potent inhibitor of myostatin. Original follistatin also worked as an inhibitor of activin, which in turn stimulates secretion of follicle stimulating hormone - FSH (activin regulates the growth and differentiation of nearly all cell types, including the gonads, pituitary and skeletal muscle). For this reason, scientists have developed from the original follistatin derived specific follistatin (follistatin-344), which is preferably capable of blocking the effects of myostatin.
