Thymalin

Preclinical, limited human dataPolypeptide extract, not a single defined sequence

Also published as Thymus polypeptide extract

A polypeptide preparation extracted from calf thymus rather than a single synthesised sequence. That distinction matters more here than anywhere else in the catalogue, because batch definition is inherently harder for an extract.

Where it came from

Developed within the same St Petersburg peptide bioregulator programme that produced Epithalon, and used clinically in Russia from the 1980s.

What the literature examines

  • T cell maturation and immune restoration in immunosuppressed models
  • Age related immune decline
  • Recovery after infection and surgery, in Russian clinical work

State of the evidence

Furthest it has gotPreclinical, limited human data

Russian clinical use and literature. Very little independent Western study.

What a buyer should know

An extract is a mixture, not a molecule. Purity figures on an analysis certificate mean something different for an extract than they do for a synthesised peptide, and any buyer comparing a 99 percent figure on thymalin against 99 percent on a synthetic sequence is not comparing like with like.

Handling and stability

Lyophilised. Cold chain.
