Follistatin 344 is a naturally occurring autocrine glycoprotein that binds to and inhibits members of the TGF-Ξ² superfamily, particularly myostatin and activin A. In research contexts, Follistatin 344 has been studied for its capacity to promote skeletal muscle hypertrophy, enhance muscle regeneration, and modulate reproductive and inflammatory pathways.
Its longer systemic half-life compared to other follistatin isoforms has made it especially relevant in studies focused on muscle wasting disorders, regenerative biology, and cellular growth signaling.
