FOXO4-DRI
Growth Hormone PeptidesFat Loss & Metabolic
Tesamorelin
Summary
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.
Tesamorelin is an FDA-approved synthetic GHRH analog specifically indicated for reduction of excess abdominal (visceral) fat in HIV patients with lipodystrophy. It is the only GHRH peptide with FDA approval for a fat-reduction indication and is studied off-label for metabolic syndrome and cognitive function.

Key Benefits
  • 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
  • FDA-approved for visceral fat reduction in HIV lipodystrophy
  • Significant reduction in trunk/visceral fat (average 15–20% in trials)
  • Improved triglyceride and lipid profiles
  • Potential cognitive benefits and memory improvement
  • Preserves lean mass while reducing fat
  • Natural pulsatile GH stimulation
Side Effects
  • 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
  • Injection site reactions (redness, irritation)
  • Arthralgia and joint pain
  • Peripheral edema
  • Carpal tunnel syndrome
