Follistatin FST


Follistatin is also known as an activating binding protein that is encoded in the human FST gene. Follistatin is a code of 344 amino acids with 29 amino acid sequence sequences. It is an autocrine glycoprotein that is expressed in almost all tissues of the upper class of animals. Its main function is the binding and bio-neutralization of members of the gf-β superfamily, a particular focus on the activated paracrine hormone. Follistatin is a sterile, non-pyrogenic white lyophilized powder designed for subcutaneous or intramuscular injection after reconstitution with sterile water for injection. An earlier name for the same protein is FSH-suppressing protein (FSP). During its initial isolation from the follicular fluid, it was found to inhibit the release of follicle stimulating hormone (FSH) in the anterior pituitary. injection after reconstitution with sterile water for injections. Its chemical structure is: Formula

Clinical pharmacology
Mechanism of action
Follistatin works by binding to the myostatin, it’s suppression and binding to the activin receptor. At the low level of follistatin in the body, the action of the
protein myostatin increases. This prevents and leads to a stagnation of muscular growth. The myostatin protein is found in muscle cells and has the function
of maintaining volume and adjusting the amount and size of muscle mass within a range. Studies have shown that the less the amount of myostatin in the
body, the greater the muscle growth can be.
Follistatin significantly increases muscle growth and increases strength by blocking myostatin activity. Increases hyperplasia (new cell growth) as well as
hypertrophy (increase in cell size). It has powerful anabolic activity without androgenic concomitant. It has strong ability to maintain the acquired form and
maintain muscle mass, even when the individual has limited training activity. It strengthens fat burning and significantly slows down aging.
Adverse reactions
The solution is used to inject the subcutaneous body into a body fat using a very small insulin needle. Follistatin also has a local effect by increasing the
size of the muscle into which it is injected so that the peptide can be injected intramuscularly. The peptide is good for most users, however, there is a
potential for side effects when using follistatin at the injection site. Pain, redness, and swelling of the skin may occur. Clinical studies have shown that there
are no side effects. Long use of the peptide is not desirable as it suppresses the secretion of FSH from the pituitary gland. This can drastically reduce sexual
desire. Woman-driven is not desirable because the peptide can cause the polycystic ovarian syndrome.
Instructions for reconstitution
The recommended and most common daily dose is from 50 to 100 μg daily intramuscularly in muscle that lags due to the local action of the peptide for 10
days after which the injection site changes and the cycle lasts for no more than 20 days followed by a rest period.
Doping test
Athletes who are subject to doping tests and use Follistatin should know that they are listed in the WADA Prohibited List. BALCO products have no marker
agents and this preparation cannot be detected by regular urine testing. In the blood test, its presence is also absolutely undetectable 6-8 hours after intake.
In a sudden blood test, GHRP-6 can be detected for about 6 hours after taking the preparation.
