Follistatin-344
Muscle growth & myostatin inhibition
Follistatin-344 is a naturally occurring glycoprotein that binds and inhibits members of the TGF-β superfamily, most notably myostatin and activin. By suppressing myostatin — the primary inhibitor of muscle growth — it has attracted significant research interest for muscle hypertrophy and wasting conditions.
- ✓Inhibits myostatin for muscle hypertrophy
- ✓Binds activin to modulate TGF-β signalling
- ✓Studied for muscle wasting conditions
- ✓Supports lean mass & strength gains
- ✓≥99% purity — HPLC verified
Mechanism of Action
Follistatin-344 is a glycoprotein that acts as a potent antagonist of activin and myostatin — members of the TGF-β superfamily. By binding and neutralising myostatin, it removes a key inhibitory brake on skeletal muscle growth. Research models use it to study muscle hypertrophy, fibrosis, and reproductive biology.
