Follistatin 344 is an autocrine glyocoprotein that is expressed in nearly every tissue that is found within animal test subjects. It is occasionally referred to as Activin-binding Protein or FST. It possesses a molecular weight of 36KDa, and its molecular formula is C13H16O3.

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 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.

Some of Follistatin 344 functions include:


The connection that Follistatin 344 has with the cells is based on the fact that the presence of the peptide has been demonstrated to play a key role in the regulatory control of cellular proliferation. In essence, Follistatin 344 works to protect an animal test subject’s body from uncontrolled cellular growth. At the same time, the peptide acts an instrument of cellular differentiation; that is, the process in which a non-specialized cellular unit becomes a more specialized cell type. According to scientific study conducted on animal test subjects, it has been determined that both of these functions play a key role in tissue building and tissue repair. This determination has led some studies to conclude that this particular aspect of functionality correlates to the peptide’s elevated presence in the skin.


It has also been determined through scientific study that Follistatin 344 plays an active role in the blood of animal test subjects. Specifically, it has been known to invoke an inflammatory response, meaning that its presences plays a role in triggering the complex biological response of vascular tissues to irritants, pathogens, damaged cells, or other potentially harmful stimuli. While it has not yet been determined where exactly the peptide generates in circulating blood plasma, it has been theorized that because of its autocrine characteristic, it may come from the endothelial cells, which are the thin layer of cells that align the inner surface of blood vessels. It has also been suggested that the peptide may originate from the white blood cells known as monocytes and or the macrophages.

Follistatin 344 Dosage:

Follistatin is recommended for research, but people who have tried it themselves typically take injection 100 mcg/day of dose via injections for 10 to 30 days. Ideally it can be taken every third day. People who have taken doses up to 200 mcg have not shown suffered from any adverse effects than the ones who have taken lower doses.


Follistatin 344 and the Life Cycle:


Further scientific studies based on animal test subejcets have also determined that the peptide plays a role in embryo development. It has been shown that the presence of the peptide has the capacity to block the proliferation of bone morphogenic proteins; a process that helps to enable the neural plate to form properly.


It has also been determined that the peptide plays a role in folliculogenesis within the ovary of female animal test subjects, meaning that their presence allows the ovarian follicle to mature and be properly equipped for the reproduction process.


According to scientific study based on animal test subjects, the primary role of the peptide appears to be attached to the progression of the follicle from the early antral stage to the antral/dominant stage, as well as the promotion of cellular differentiation of estrogen producing granulose cells into the progestrone producing large lutein cells. One of the reasons that the peptide has been connected to the ovaries in this manner is due to the fact that the highest concentration of FS cells produced by the anterior pituitary gland is found within the female ovary.
