Thymalin is a polypeptide bioregulator extracted from the thymus, the gland where T-cells mature and which shrinks with age. It came out of the Khavinson bioregulator program in Russia, where long-term studies reported immune and longevity benefits. Western RCT data is thin, which is exactly why that Russian cohort work draws attention.
- A polypeptide complex extracted from the thymus, the gland where T-cells mature and which shrinks with age.PubMed: thymalin
- Reported to support T-cell production and immune regulation in the Khavinson bioregulator literature.PubMed: thymalin
- Longevity benefits come from long-term Russian cohort studies rather than Western RCTs.Russian cohort data (Khavinson)
- Distinct from Thymosin Alpha-1: Thymalin is a thymic peptide complex, not a single defined peptide, though their immune aims overlap.The Complete Peptide Guide p.104
- Generally well tolerated in the reported literature, with mild local reaction the main noted effect and allergic response rare.The Complete Peptide Guide p.104
