Follistatin 344 95 1mg

Follistatin-344 is the primary circulating isoform of follistatin, a single-chain glycoprotein that binds and neutralizes activin, myostatin, and other TGF-β superfamily members. Research has investigated follistatin’s role in skeletal muscle hypertrophy (via myostatin antagonism), reproductive biology, and embryonic development. The 1mg format is suited for in vitro binding assays and small-scale preclinical studies.

Third-party HPLC and MS/MS tested to 99%+ purity. COA provided.
