Follistatin 344 is a naturally occurring autocrine glycoprotein that binds to and inhibits members of the TGF-β 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.
This compound is offered as a lyophilized powder in sterile, unlabeled glass vials to ensure purity and versatility in research settings. Our 10-vial research kits are produced under stringent quality control protocols and are independently batch-tested for identity and purity.
Each vial is intended for in vitro use only. Not for human consumption. Not for therapeutic or diagnostic purposes.
