  • Thymalin
  • Thymus gland (immune)
  • Stimulates thymic epithelial cells to produce thymosin and thymic hormones, restoring T-cell maturation and proliferation
  • 10mg/day
  • Morning (7–9 AM)
  • 20 days
  • First-line peptide in the stack. Restores immune foundation before neuroendocrine modulation begins
  • Cartalax
  • Hypothalamus (neuroendocrine)
  • Normalizes HPA axis function, regulates cortisol rhythm, improves hypothalamic feedback sensitivity
  • Evening (6–8 PM)
  • Second-phase peptide. Requires functional immune signaling (from thymalin) to achieve full neuroendocrine benefit
  • Epithalon (comparison)
  • Pineal gland (circadian/telomere)
  • Stimulates pineal melatonin production, activates telomerase in somatic cells
  • Evening (8–10 PM)
  • 10–20 days
  • Often stacked with thymalin-cartalax in longevity-focused protocols but addresses a separate pathway (cellular senescence vs immune-neuroendocrine axis)
  • Vilon (comparison)
  • Thymus (immune alternative)
  • Peptide bioregulator with overlapping thymic targets but different amino acid sequence than thymalin
  • Morning
  • Functional substitute for thymalin in some protocols but not validated in combination with cartalax in published Khavinson research
