Side-by-side comparison of key properties, dosing, and research.

Anti-Aging & Longevity
Epithalon
Fat Loss & Metabolic
AOD-9604
Summary
Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.

Key Benefits
  • Activates telomerase enzyme, extending telomere length
  • May slow cellular and biological aging
  • Regulates melatonin production and circadian rhythms
  • Improves sleep quality
  • Powerful antioxidant properties
  • May reduce incidence of age-related diseases
  • Supports immune system function
  • Studied for cancer prevention properties in animal models
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
  • Improved bioavailability over Fragment 176-191
  • GRAS (Generally Recognized As Safe) status in Australia
  • Potential cartilage repair and anti-inflammatory properties
  • Does not suppress natural GH production
Side Effects
