Anti-Aging & Longevity
FOXO4-DRI
Summary
AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
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.

5 mg/kg in rodent studies; human equivalent approximately 0.5-1 mg/kg
Frequency
3–5 times per week
3 consecutive days per cycle
Key Benefits
  • AMPK activation mimics aerobic exercise adaptations
  • Increased fat oxidation and endurance
  • Mitochondrial biogenesis (PGC-1alpha)
  • Improved insulin sensitivity and glucose metabolism
  • Anti-inflammatory effects
  • Potential cardiac protection during ischemia
  • Synergistic with actual exercise training
  • Reduces hepatic glucose production
  • 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
  • Hypoglycemia risk
  • Lactic acidosis at high doses (animal data)
  • Injection site irritation
  • 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
