Summary
Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland extract Thymalin. The shortest immune-regulatory peptide known, Vilon modulates T-cell and NK-cell function, extends lifespan in animal models, and shows epigenetic anti-aging activity. It is one of the Khavinson peptide bioregulators.
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.
Half-Life
Very short as a free dipeptide; effects mediated via gene regulation
~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks

Key Benefits
  • Immune system modulation and restoration
  • Lifespan extension (30–40% in animal studies)
  • T-cell and NK-cell activation
  • Epigenetic anti-aging activity
  • Reduces oxidative stress markers
  • Antioxidant gene upregulation
  • May prevent age-related immune senescence
  • Anti-tumor immune surveillance
  • 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
Side Effects
  • Excellent safety profile, decades of Russian clinical use
  • Rare: mild injection site reaction
  • Very rare: mild allergic reaction
  • Generally very well tolerated
  • Rare: mild GI discomfort at high doses
  • May temporarily reduce some gut bacteria species
  • Rare: headache at initiation
