Follistatin
Fat Loss & Metabolic
Adipotide
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.
Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.

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
  • Targeted reduction of white adipose tissue
  • Promotes fat vasculature apoptosis without systemic toxicity
  • Demonstrated significant fat loss in primate studies
  • Potential for visceral and subcutaneous fat reduction
  • Novel non-hormonal mechanism distinct from GLP-1 agonists
  • Explored for obesity and metabolic syndrome
Side Effects
  • Potential for excessive muscle growth if doses are not controlled
  • FSH suppression with implications for fertility in women
  • Theoretical risk of cardiac hypertrophy with prolonged high-dose use
  • Limited human safety data available
  • +1 more
  • Renal toxicity observed in primate studies (transient, dose-dependent)
  • Dehydration and electrolyte imbalances in research
  • Weight regain upon cessation
  • Limited human data; side effect profile largely from animal studies
