- 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
