Anti-Aging & Longevity
FOXO4-DRI
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.
FOXO4-DRI is a D-retro-inverso peptide derived from the FOXO4 protein that selectively induces apoptosis in senescent cells. By disrupting the FOXO4-p53 interaction that keeps senescent cells alive, it triggers programmed cell death specifically in these aging, pro-inflammatory cells while sparing healthy tissue.
Half-Life
Short (minutes); sustained gene-regulatory effects
Estimated 2-4 hours (D-amino acid confers resistance to proteolysis)
Admin Route
SubQ, Oral
Subcutaneous, Intraperitoneal (research)
Research
Typical Dose
10 mg per day
5 mg/kg in rodent studies; human equivalent approximately 0.5-1 mg/kg
Frequency
Daily for 10–30 days
3 consecutive days per cycle
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
  • Selectively clears senescent cells (senolytics)
  • Reduces senescence-associated secretory phenotype (SASP) and chronic inflammation
  • Demonstrated restoration of physical fitness in aged mice
  • May improve healthspan and reduce age-related tissue dysfunction
  • Potential for treatment of age-related pathologies driven by cellular senescence
  • Does not affect healthy non-senescent cells at therapeutic doses
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No clinically significant hepatotoxicity reported
  • Limited human data; largely preclinical evidence
  • Possible temporary inflammatory response as senescent cells are cleared (senolytic effect)
  • Weight loss observed at high doses in rodent studies
  • Unknown long-term safety profile in humans
