Follistatin 344
Summary
KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
Follistatin 344 is a recombinant form of the endogenous follistatin protein. It inhibits myostatin and activin — the primary negative regulators of muscle growth — potentially removing the genetic ceiling on muscle development. It is one of the most theoretically powerful anabolic compounds but is experimental with limited human data.
Half-Life
Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
~24–36 hours

Key Benefits
  • Reduces intestinal inflammation (IBD, Crohn's, colitis)
  • Promotes gut mucosal healing and barrier integrity
  • Accelerates wound healing topically
  • Suppresses systemic inflammatory cytokines
  • Antimicrobial properties against pathogens
  • Reduces neuroinflammation when administered systemically
  • May improve symptoms of inflammatory skin conditions
  • Inhibits myostatin — removes muscle growth ceiling
  • Significant increases in muscle mass and strength
  • Reduces fat mass
  • Promotes bone density
  • May stimulate hair follicle cycling
  • Anti-fibrotic effects in muscle tissue
  • Synergistic with IGF-1 and other anabolic peptides
Side Effects
  • Generally very well tolerated
  • Mild injection site reactions (SC)
  • Rare: transient flushing
  • Muscle soreness (from rapid hypertrophy)
  • Potential reproductive effects (activin inhibition)
  • Unknown long-term safety profile
  • Possible esophageal effects at high doses (animal data)
