High Purity FST Healthy Peptide Follistatin 344 1mg as Muscle Building Peptides

Follistatin 344 Application:

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, follistatin can inhibit the activity of other TGF-Beta ligands i

ncluding 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.

Follistatin 344 Introduction​:

Follistatin (FS) was initially identified as a follicle-stimulating hormone inhibiting substance found in ovarian follicular fluid. FS is a high-affinity activin-binding protein that can act as an activin antagonist. Two alternatively spliced follistatin mRNAs exist, encoding mature FS with 288 amino acid (aa) residues (FS-288) and 315 aa residues (FS-315). Natural FS purified from porcine ovaries is primarily a carboxy-terminal truncated form of FS-315 composed of 300 aa residues.

Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. The single FST gene encodes two isoforms, FST317 and FST344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. In a study in which 37 candidate genes were tested for linkage and association with polycystic ovary syndrome (PCOS) or hyperandrogenemia in 150 families, evidence was found for linkage between PCOS and follistatin. Follistatin binds directly to activin and functions as an activin antagonist. specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (fsh).

 Double Muscles for Life with Just One Injection of Follistatin Gene

You can nag your dealer until he pins you on to the fender of his SUV, but you still won’t get any. We’re talking about the anabolic wonder stuff that researchers at Ohio State University are doing experiments with. A single injection will change you for the rest of your life into a hulk of the kind that Markus Ruehl [see photo below] would say: that much muscle just isn’t aesthetic.

The super steroid in question is not a hormone. It’s a common-cold virus that the researchers have made some adjustments to.

Viruses invade cells and release their genes into them. Then the cell obeys the virus genes’ instructions, and makes the proteins according to the genes’ blueprint. The proteins formed are the building blocks for new viruses.

The researchers managed to get their viruses to ‘programme’ the muscle cells to make proteins that deactivated the myostatin protein. Myostatin is a protein that muscle cells make to prevent fitness centre owners from having to change jobs and become SUV salesmen.

Not that the researchers had something against fitness centre owners. They are looking for a cure for muscular dystrophy. In their study, which was published in the prestigious PNAS, they tested three myostatin inhibiting genes: the gene for growth and differentiation factor-associated serum protein-1 (GASP-1), follistatin-related gene (FLRG) and the gene for follistatin-344 (FS).

There are various kinds of follistatin and they all have different functions. As far as we know, only follistatin-344 is active in muscle tissue.
