Does follistatin build muscle?

Follistatin has emerged as a powerful antagonist of myostatin that can increase muscle mass and strength.

What is follistatin peptide?

Follistatin is an autocrine glycoprotein that is expressed in nearly all tissues of higher animals. Its primary function is the binding and bioneutralization of members of the TGF-β superfamily, with a particular focus on activin, a paracrine hormone.

Do eggs contain 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.

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.

Will peptides make me bigger?

Supplement companies often tout peptides to boost muscle growth, promote fat loss, or improve workout performance and recovery. However, strong research does not back many of these claims. Very little evidence is available on the effects of peptides in well-trained individuals like bodybuilders.

Will peptides build muscle?

Specific peptides may also help boost the release of hormones known to stimulate muscle growth, body fat loss, and exercise performance and recovery. This makes them particularly appealing to bodybuilders interested in maximizing their training results ( 1 , 6 ).

What is myostatin blocker?

Myostatin inhibitors are a group of molecules that block myostatin, and may work to improve muscle mass and strength in children with muscle-wasting diseases. They are being investigated as potential treatments for diseases such as muscular dystrophy.

How does follistatin help to increase muscle growth?

One way that follistatin may accelerate muscle growth is by inhibiting myostatin, a protein that limits muscle development [ 15, 16, 17 ]. For example, a monkey study found that increasing the production of follistatin led to a corresponding decrease in myostatin activity and a significant increase in muscle growth [ 18 ].

How are peptides used in the bodybuilding industry?

For example, IGF-1 peptides work by boosting the insulin-like growth of muscles in both men and women (1). According to the Australian Crime Commission (ACC), there is a widespread use of peptides in professional sports all over the world. Athletes and fitness fanatics alike are using these mini-proteins primarily to accelerate their recovery.

How is follicle stimulating hormone related to reproductive health?

Follicle-stimulating hormone ( FSH ), involved in the development of eggs and sperm (gametes) [ 12 ]. Most of the follistatin’s effects on cancer and in reproductive health stem from its interactions with activins [ 4 ]. In contrast, follistatin’s effects on muscle growth are related to interactions with myostatin [ 13 ].

How does epicatechin work to increase follistatin levels?

In old mice, daily injections of epicatechin (a natural compound that increases follistatin levels) led to increased overall muscle strength. The same treatment in 6 human subjects increased their hand grip strength after seven days [ 20 ].
