Follistatin 344 1mg | Myostatin Inhibitor Peptide | Muscle Growth & Regeneration Research 

Follistatin 344 is a naturally occurring glycoprotein peptide that functions as a potent inhibitor of myostatin (GDF-8) and activin — key regulators of muscle growth and tissue development.

At West Lab Chemicals, we supply Follistatin 344 1mg (Research Grade) with ≥99% purity (HPLC verified), produced in GMP-certified facilities for precise, reliable, and consistent research outcomes.

This peptide is widely used in muscle regeneration, gene expression, and tissue remodeling research, as well as in studies exploring cell differentiation, growth regulation, and protein synthesis pathways.

What is Follistatin 344?

Follistatin 344 (FS-344) is a 344–amino acid peptide fragment derived from the full-length follistatin protein, a binding protein for TGF-β (Transforming Growth Factor Beta) superfamily members, especially myostatin and activin.

By neutralizing these growth inhibitors, Follistatin 344 enables enhanced muscle fiber hypertrophy and accelerated tissue repair in experimental research.

Mechanism of Action:

• Binds and inhibits myostatin (GDF-8) — preventing muscle growth suppression

• Modulates activin A signaling — involved in fertility, growth, and wound healing

• Promotes satellite cell activation and muscle regeneration

• Stimulates protein synthesis and reduces muscle breakdown
