What is Thymalin?
Thymalin, also spelled Timalin, is a peptide preparation derived from thymus tissue. Unlike the synthetic short peptides of the same research line, it is not a single defined sequence. It is one of the thymus peptide preparations studied by Vladimir Khavinson’s group at the St. Petersburg Institute of Bioregulation and Gerontology.
Thymalin product specifications
- Compound: Thymalin (thymus peptide preparation)

Regulatory status
Thymalin is used as a medicine in Russia but is not an approved medicine in the US, UK, EU or Canada. This product is sold for laboratory research use only.
Related bioregulator peptides
- Thymagen (Thymogen) is a synthetic dipeptide (Glu-Trp) from the same thymus research.
- Thymosin Alpha-1 is a different, single-sequence thymus peptide.
- Epithalon is the best-known peptide of the Khavinson research line.
Available sizes: 10mg and 25mg
Thymalin is offered in two vial sizes: 10mg and 25mg. Both contain the same peptide. The figure is the total amount of peptide in the vial, supplied as a dry (lyophilised) powder; it is not a concentration, so a larger vial is not “stronger”, it simply holds more material.
