Adipotide
Summary
Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.
Half-Life
~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
Estimated 2-4 hours
Admin Route
Oral
Subcutaneous, Intravenous (research)
Research
Typical Dose
1–5 mg
Not established for humans; primate studies used 0.1-1 mg/kg
Frequency
Once daily
Daily for 4 weeks (research protocol)
Key Benefits
  • Induces autophagy — cellular self-cleaning
  • Extends lifespan in yeast, flies, worms, and mice
  • Reduces cardiovascular aging and arterial stiffness
  • Reduces all-cause mortality (human epidemiological data)
  • Neuroprotective: reduces amyloid and tau pathology
  • Promotes hair growth (anagen phase activation)
  • Reduces age-related immune decline
  • Improves memory in aging models
  • Targeted reduction of white adipose tissue
  • Promotes fat vasculature apoptosis without systemic toxicity
  • Demonstrated significant fat loss in primate studies
  • Potential for visceral and subcutaneous fat reduction
  • Novel non-hormonal mechanism distinct from GLP-1 agonists
  • Explored for obesity and metabolic syndrome
Side Effects
  • Generally very well tolerated
  • Rare: mild GI discomfort at high doses
  • May temporarily reduce some gut bacteria species
  • Rare: headache at initiation
  • Renal toxicity observed in primate studies (transient, dose-dependent)
  • Dehydration and electrolyte imbalances in research
  • Weight regain upon cessation
  • Limited human data; side effect profile largely from animal studies
