What is Follistatin 344 and Does it Build Muscle?
Follistatin is fascinating protein that can increase muscle mass beyond natural potential by suppressing myostatin. Scientists first identified follistatin while examining porcine (re: pig) follicular fluid in the ovaries. [1]
Follistatin is naturally found in the skeletal muscle of almost all mammals with advanced or developed characteristics, such as humans, rodents, and cows. Follistatin is high in the non-essential amino acid cystine but unlike most proteins discussed in the fitness world, follistatin has carbohydrates attached to it. [2]
Follistatin, specifically Follistatin 344 (FS344), quickly gained popularity in the bodybuilding community as a potential supplement to rapidly increase lean tissue mass. Another protein, follistatin-related gene (FLRG) acts on similar pathways as FS344 regarding its muscle building properties. Increased lean tissue mass could give a bodybuilder an advantage in a competitive setting and be the differentiating factor between first and second place.
 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. [4] [5]
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. [6] 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.
Does Follistatin Build Muscle?
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. [8] 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. [7]
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.[1] [3] 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. [2]
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. [7] Less muscle mass at birth can negatively impact bone, organ, and tissue development as well as normal hormonal function.
Follistatin 344 (FST-344)
Follistatin (FST) is a secreted glycoprotein that was first identified as a follicleÂstimulating 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 NÂterminal atypical TGF binding domain, three Follistatin domains that contain EGFÂlike and kazalÂlike motifs, and a highly acidic CÂterminal 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.
