Follistatin 344

FDA: research-only

Follistatin 344 binds and inhibits myostatin, a protein that limits muscle growth. By reducing myostatin activity, it removes the genetic cap on muscle size, promoting hypertrophy, regeneration, and creating a hyper-anabolic microenvironment post-workout. Blocks myostatin, the protein that naturally limits muscle growth. Creates hyper-anabolic microenvironment post-workout by removing the genetic ceiling on hypertrophy. Also plays a role in inflammation and fibrosis reduction. - Removes genetic cap on muscle size - Muscle hypertrophy and strength gains - Anti-fibrotic effects - Regeneration support - Creates optimal anabolic conditions post-training - Standard: 100 mcg/day IM for 10-20 days (cycle carefully) - Pulse: 100
