Follistatin 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).

 

 

Follistatin and Muscle Growth

 

Follistatin works by binding to and inhibiting transforming growth factor-β (TGF-β) peptides such as myostatin which is responsible for regulating and limiting muscle growth. [3] It’s also worth pointing out that myostatin may have a regulatory role in skeletal muscle fibrosis; too much myostatin can impair tissue function and cause chronic disease in vital organs, tissues, and bone marrow. [

 

In additional to suppressing the degenerative properties of myostatin, follistatin also suppresses the pituitary gland synthesis and secretion of follicle-stimulating hormone (FSH). [1] High FSH levels in men may indicate that testicles are not functioning correctly; this condition limits muscle growth, recovery, and normal hormonal function. However, FSH levels that are too low can also negatively impact health and reproductive capabilities.

 

Whereas some myostatin inhibitors like Trichostatin A (TSA) require daily administration, increased levels of FS344 were observed up to 15 months after initial injection. [7][3] The lack of need for daily administration makes follistatin an attractive alternative for suppressing myostatin.

 

The recent increase in attention in the science community on follistatin and other myostatin inhibitors is primarily due to the desire to find an alternative means to treat muscle disorders; the most popular current option is androgen steroids which pose a number of side-effects and long-term health risks. At this point you might be wondering why follistatin use isn’t more widespread in bodybuilders and other athletes. In the next section we will examine the current research on follistatin and whether it builds muscle mass.

Building Muscle of Follistatin 344

 

In short, follistatin does build muscle but not necessarily in humans. A number of studies support the muscle-building and anti-degenerative effects follistatin in rodents. Unfortunately there is no formal research examining follistatin usage in human subjects but a quick Google search will yield countless amateur follistatin logs on bodybuilding and fitness forums.

 

When scientists bred a mouse producing no myostatin and extra follistatin it had 117% larger muscle fibers and 73% more total muscle fibers compared to the mice in the control group. This study demonstrates that follistatin positively impacts muscle growth in ways beyond simply suppressing myostatin. Mice with suppressed myostatin had twice the muscle mass but mice with the follistatin transgene and suppressed myostatin had four times as much muscle mass compared to the control group.

 

Administering FS344 via a small virus (re: adeno-associated virus/AAV) can increase muscle size and strength in animal species ranging from mice to monkeys with no significant adverse effects on organs, reproductive capabilities, serum estradiol (re: primary female sex hormone), luteinizing hormone (LH), and FSH levels. When scientists administered follistatin in mice with spinal muscular atrophy, the mice experienced increased muscle mass, improved motor function, and a 30% longer lifespan compared to mice in the control group. 

 

Not only do increased follistatin levels correlate to increased muscle mass, but a lack of the follistatin protein at birth directly correlates to less muscle mass. Less muscle mass at birth can negatively impact bone, organ, and tissue development as well as normal hormonal function.

 

 

Effects

 

1) Follistatin 344 / FST promote muscle growth due to the unique mechanism of action, FST joint use of steroids, IGF has better results. It only acts on muscle tissue , after use will not cause the proliferation of other tissue cells.

 

2) Follistatin 344 / FST works by binding to and inhibiting transforming growth factor-β (TGF-β) peptides such as myostatin which is responsible for regulating and limiting muscle growth

 

 

Functions:

 

Anti edema,
Improve microcirculation of the blood,
Strengthen blood circulation,
Eliminate inflammation,
Resist pouch and dilute the fine lines and cow's feet around eyes
Delay the effects of premature aging by improving the elasticity and firmness of the skin.
Hydrate, protect and smooth skin.

 

 

Storage


Follistatin 344 Lyophilized Follistatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FST should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
