Overview
Thymalin is a synthetic peptide bioregulator derived from calf thymus tissue extract (Thymalin polypeptide complex), developed as part of the St. Petersburg Institute of Bioregulation and Gerontology’s cytomedine program and studied extensively by Vladimir Khavinson’s research group. Representing the thymus component of the cytomedine bioregulator class, Thymalin’s published research examines its immunomodulatory effects on T-cell differentiation, thymic hormone biology, and aging-associated immune decline. It has been studied in both animal models and clinical settings in Russia, with published literature spanning immune function, longevity biology, and hematopoietic system research.
What It Is
Thymalin is a polypeptide fraction isolated from bovine (calf) thymus tissue, containing a mixture of short peptide bioregulators in the 1,000–10,000 Da range. Unlike chemically defined single-sequence peptides, thymalin is characterized by its biological activity profile rather than a single molecular formula. Key active components identified in the Khavinson research program include dipeptides Lys-Glu and Glu-Trp. MW range: 1–10 kDa. CAS number associated with the polypeptide complex: 58929-31-0.

Frequently Asked Questions
Thymalin is a peptide fraction extracted from calf thymus. It has been studied for effects on T-lymphocyte differentiation. The thymus involutes with age, reducing the output of naive T cells, which is why thymic peptides are studied in immune-ageing research.
Mostly from Vladimir Khavinson's group in St. Petersburg, and much of it has not been independently replicated. Portal to Wellness does not publish protocols, combinations or quantities, and nothing on this page is a recommendation for use.
