Follistatin
Anti-Aging & Longevity
Ovagen
Summary
Follistatin is an endogenous glycoprotein that acts as a potent inhibitor of myostatin and activin, two proteins that limit muscle growth. By binding and neutralizing myostatin, follistatin removes the primary brake on skeletal muscle hypertrophy, enabling significant muscle growth beyond normal physiological limits. It is distinct from its isoforms Follistatin 315 and Follistatin 344 in tissue distribution and binding affinity.
Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.

Key Benefits
  • Potent myostatin inhibition enabling supraphysiological muscle growth
  • Increases skeletal muscle mass and fiber size
  • May accelerate recovery from muscle injury
  • Potential benefits in muscular dystrophy and sarcopenia
  • Synergistic with IGF-1 and growth hormone in anabolic protocols
  • Animal studies show dramatic increases in muscle mass
  • Reduces muscle fibrosis in dystrophic models
  • Hepatoprotective effects against toxic, viral, and metabolic liver damage
  • Promotes hepatocyte regeneration and liver tissue repair
  • May reduce liver fibrosis progression
  • Supports liver metabolic function and detoxification capacity
  • Anti-aging effects on hepatic tissue
  • Useful in NAFLD/MASH supportive protocols
  • Compatible with NAD+, glutathione, and BPC-157 in liver health stacks
Side Effects
