Follistatin 344 significantly increases growth and strength of muscles by blocking Myostatin (GDF-8 – a protein inhibiting muscle growth). Follistatin-344 seems to be a very promising Myostatin inhibitor, possessing a sufficient safety profile.

Follistatin 344 is also a perfect choice for those sportsmen who cannot exercise on a regular basis any longer or for those who stopped exercising, but they still want to stay in shape, having a huge muscle mass. It has been proved, that the less strenuous muscle load and the less physical activity is, the higher concentration of Myostatin is reached.

Follistatin 344 (also known as activin-binding protein) is an autocrine glycoprotein encoded by the FST gene that is expressed in nearly all tissues. Its primary function in the body is bioneutralization of members of the TGF-β superfamily, with a particular focus on activin and paracrine hormones.

Follistatin is a potent Moystatin inhibitor. An original Follistatin 344 acted also as an activin inhibitor, which on the other hand stimulates the secretion of follicle-stimulating hormone – FSH (activin regulates the growth and differentiation of all cell types, including cells within sexual glands, pituitary gland and skeletal muscles). Therefore, scientists developed a particular Follistatin (Follistatin 344) that is derived from the original one and that is capable of blocking preferentially Moystatin activity.

100 mg per day

10 ml – 1 mg

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.

Follistatin 344 application course lasts for 10-20 days. The standard dosage is 100 mg per day. The peptide is administered subcutaneously. Actively used in powerlifting and bodybuilding.

The Following Peptides are useful for adding muscle and is a good idea to add into any stack where you are trying to add muscle: IGF-1 LR3, IGF-1 DES, PEG-MGF, MGF, LGD-4033, and, Ostarine.

As a rule, Follistatin 344 does not cause side effects, even if they do occur they are reversible and are temporary in nature, without affecting the daily life. The following side effects may occur: redness and pain at the injection site, not of the prolonged nature; deterioration of folliculogenesis, the effect may have a negative impact on the work of ovaries, when women used the drug.

Not recommended in case of hypersensitivity to Follistatin 344, prostate or breast carcinoma, prostate hyperplasia symptoms, nephrosis, edema, hypercalcemia, liver function disorders, diabetes, heart failure or coronary myocardial infarction, atherosclerosis in elderly men. Not to be used by teenagers to avoid premature cessation of growth and puberty.
