Ovagen vs Dihexa

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

Anti-Aging & Longevity
Ovagen
Cognitive Enhancement
Dihexa
Summary
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.
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.

Key Benefits
  • 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
