Do bodybuilders use follistatin?
Follistatin is a well-kept secret in the bodybuilding community. The science on this valuable protein is still relatively new, but according to limited human research, a follistatin supplement can increase muscle growth up to 200 percent, help you shed body fat, and enhance fertility, whether you’re a man or a woman.
How do I take follistatin 344?
According to sites selling the drug over the internet, a subcutaneous injection of 100–200 mcg per day for a period of 10–20 days is recommended for 1 mg follistatin-344. Follistatin-344 inhibits myostatin, which is responsible for regulating and limiting muscle growth, leading to an increase in muscle mass [9].
Where is follistatin found?
Although FS is ubiquitous its highest concentration has been found to be in the female ovary, followed by the skin. The activin-binding protein follistatin is produced by folliculostellate (FS) cells of the anterior pituitary.
How much follistatin is in an egg?
It has been found that the egg white of fertilized hen eggs (Gallus domesticus) has a follistatin concentration of approx. 15 to 30 µg/kg, whereas the egg yolk only contained 1 to 3 µg/kg and approx. 30 % by weight (wt-%) fats.
How do you store follistatin?
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.
What contains follistatin?
Follistatin can be found commonly in the food supply in egg yolks. Fertilized egg yolks are particularly high in follistatin levels. Fertilized egg yolk derived products have been created and patented for use as dietary supplement ingredients including one called Fortetropin®, formerly known as Myo-T12.
What is follistatin gene?
Summary. 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.
Do eggs have follistatin?

Read on to learn more about follistatin and how you can boost its levels with foods and supplements.
How does follistatin affect muscle growth in mice?
However, follistatin increased muscle growth even in mice that were genetically modified to lack myostatin, showing that follistatin affects muscle growth in other ways that are not directly related to myostatin [ 16, 19 ]. Although this is the most common use of follistatin, the evidence to support it is insufficient.
Is it legal to take follistatin 344 in humans?
Although follistatin 344 is not legal to purchase for human consumption, scientists have discovered several benefits regarding this peptide hormone. Research is still relatively new, but it does show that follistatin 344 intake can increase muscle growth by up to 200 percent.
