Follistatin 344 Research Overview

Follistatin 344 is a naturally occurring 344-amino acid glycoprotein isoform that acts as a potent antagonist of myostatin, activin A, and related TGF-β superfamily ligands — studied for its extraordinary capacity to promote skeletal muscle hypertrophy, reverse muscle wasting, and regulate reproductive biology through high-affinity ligand sequestration.
