Follistatin 344 is a recombinant form of the naturally occurring glycoprotein follistatin (FST344 isoform). It binds and neutralizes activin, myostatin, and other TGF-Ξ² superfamily members. Research has demonstrated its role in muscle growth promotion through myostatin inhibition, reproductive biology, and inflammatory modulation. The 344-amino acid isoform is the most commonly studied variant in muscle biology research.
