Key Aspects of Follistatin 344

Mechanism of Action: Follistatin 344 acts primarily as a myostatin inhibitor and binds to the activin type IIB receptor (ActRIIB), effectively promoting muscle hypertrophy.
Muscle Growth: Studies using adeno-associated virus (AAV1)-FS344 vectors have demonstrated significant increases in muscle size and strength, with studies in macaques showing muscle enlargement and increased twitch force.
Research Applications: Beyond bodybuilding, it is being researched for mitigating muscular dystrophy, treating muscle atrophy, and its role in tissue regeneration.
