Full research summary5 citations

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.

  • 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

Storage & handling

Lyophilized at -4°F; in solution, refrigerated at 36 to 46°F, with the potency window estimated near 2 to 4 weeks (community estimate, no published data).

Research cautions

Immune modulation could theoretically aggravate autoimmune conditions, so active autoimmune flare, deliberate immunosuppression and pregnancy are exclusions, and source quality varies enough that a COA matters.
