Body Building Peptide Follistatin 344 (1 mg/vial) ----- Follistatin 315 (1 mg/vial)




Follistatin 344 is an activin-binding protein that aid muscle repair process and also improve


motor functions. It is is made up of 323 amino acids.



It binds directly with activin and acts as an activin antagonist. Follistatin 344 is a selective


inhibitor of biosynthesis and secretion of pituitary follicle stimulating hormone (FSH). Follistatin


344 is a potent myostatin inhibitor and promotes muscle growth this is due to the fact it blocks


myostatin. The peptide is preferred by athletes who are unable to exercise regularly or opt out


from sports activities but need massive muscle mass. Research studies demonstrated the anti-


aging and tissue rejuvenation effects of Follistatin, it is also a glycoprotein encoded by the FST


gene which means that it is widely distributed in all tissues. A single follistatin gene encodes to


various isoforms including FST317 and FST344.



These isoforms are made up of 317 and 344 amino acids that promote alternative splicing of


mRNA. Molecular biological studies have identified potential linkage between polycystic ovarian


syndrome and follistatin genes. It was first discovered as follicle stimulating hormone compound


in the ovarian follicle fluid. The human Follistatin CDNA encodes for a 344 amino acid protein


with 29 amino acids signaling the sequence. The domain that encodes for the EGF has kazallike


motifs and a highly acidic C-terminal. The secreted Follistatin binds to TGF-family ligand as


indicated and it regulates the activity of the signaling receptors. Previous studies had shown that


the polypeptide is an antagonist to activin. Moreover apart from being an antagonist to activin,


Follistatin inhibits activities of other TGF-beta ligand such as GDF-11, BMP-2,-4,-6 and


myostatin among others. In most cases, Follistatin is expressed in the ovaries, pituitary gland,


and endometrial cells in some cases.



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 .
