Description
Follistatin 344 is a research peptide known for its ability to inhibit myostatin — a protein that restricts muscle growth. By blocking myostatin, Follistatin promotes dramatic increases in muscle mass, strength, and tissue regeneration. It also interacts with other members of the TGF-β (Transforming Growth Factor Beta) family, including activin.
Follistatin 344 is a systemic version of the naturally occurring Follistatin protein and is used in research examining muscle-wasting conditions, sarcopenia, and performance enhancement. Its potent anabolic activity has made it a key focus in muscle development and longevity science.
