Follistatin (FST) is a secreted glycoprotein that was first identified as a folliclestimulating 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, this peptide 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.

Description

How does Follistatin 344 work?

The amino acid cysteine present in Follistatin 344 inhibits the dominance of myostatin, another natural protein present in human beings that prevents muscle growth and weight gain. Therefore, this product suppresses myostatin hence achieving far above natural results in muscle growth and weight gain.

Apart from myostatin, there are other growth-inhibiting peptides in human bodies that Follistatin 344 suppresses hence achieving the desired results.

Follistatin 344 has gained popularity in the spheres of bodybuilding industry due to its above-average results to its users.

Health benefits of Follistatin 344

Follistatin 344 as a natural protein comes with numerous health benefits. The benefits include:

  • Building lean muscles from the body tissue
  • Controls and inhibits the negative effects of myostatin e.g. fibrosis
  • Can be used intermittently and irregularly with great results
  • Short user cycles of ten days enable healing of any side effects hence favoring active athletes
