Thymalin is a polypeptide complex isolated from the calf thymus gland, consisting of a mixture of bioactive peptides that modulate immune system function. Developed at the Saint Petersburg Institute of Bioregulation and Gerontology, Thymalin has been used clinically in Russia and CIS countries for immunomodulation, treatment of immunodeficiency states, and as a geroprotective agent. It represents the natural thymic peptide extract approach to immune regulation. We provide research-grade Thymalin in lyophilized form for institutional research applications.

Khavinson VK (2002) published in Neuroendocrinology Letters a comprehensive review demonstrating Thymalin's immunomodulatory effects through restoration of T-cell immunity and cytokine regulation.
Research by Kuznik BI et al. (2015) in Advances in Gerontology documented Thymalin's geroprotective properties, including improvements in immune markers and reduced morbidity in elderly populations.
A long-term clinical study published in Bulletin of Experimental Biology and Medicine (2003) demonstrated significant immune restoration following Thymalin administration in immunocompromised patients.
Thymalin is a polypeptide complex extracted from calf thymus gland, containing a mixture of bioactive peptides that regulate immune system function. It was developed at the Saint Petersburg Institute of Bioregulation and Gerontology.
We supply Thymalin with ≥95% total peptide content, verified by HPLC and UV spectrophotometry. As a natural peptide complex, purity is assessed by total peptide content rather than single-compound HPLC.
Thymalin is a natural thymic extract containing multiple peptides, while Thymosin Alpha-1 (Tα1) is a single synthetic 28-amino acid peptide. Both modulate immunity, but through different mechanisms and peptide compositions.
MOQ depends on the quantity required. Contact our sales team for specific pricing and availability information.
Store Thymalin at -20°C in lyophilized form. After reconstitution, store at 2-8°C and use within 10 days to maintain bioactivity.
