Benefit:
Follistatin (FST) is a secreted glycoprotein that was first identified as a
follicle stimulating hormone inhibiting substance in ovarian follicular
fluid (1, 2). Human Follistatin cDNA encodes a 344 amino acid (aa) protein
with a 29 aa signal sequence, an Nterminal atypical TGF binding domain,
three Follistatin domains that contain EGFlike and kazallike motifs, and a
highly acidic Cterminal tail. Follistatin is a secreted protein that binds
to ligands of the TGF-Beta family and regulates their activity by inhibiting
their access to signaling receptors. It was originally discovered as activin
antagonists whose activity suppresses expression and secretion of the
pituitary hormone FSH (follicle stimulating hormone). In addition to being a
natural antagonist, follistatin can inhibit the activity of other TGF-Beta
ligands including BMP-2, -4, -6, -7, Myostatin, GDF-11, and TGF-Beta1.
Follistatin is expressed in the pituitary, ovaries, decidual cells of the
endometrium, and in some other tissues. Recombinant human Follistatin is a
37.8 kDa protein containing 344 amino acids .

Application:
Follistatin, specifically Follistatin 344 (FS344), quickly gained popularity
in the bodybuilding community as a potential supplement to rapidly increase
lean tissue mass. Another protein, follistatin-related gene (FLRG) acts on
similar pathways as FS344 regarding its muscle building properties.
Increased lean tissue mass could give a bodybuilder an advantage in a
competitive setting and be the differentiating factor between first and
second place.
