Механизм действия
TB-500
Synthetic fragment of the endogenous protein Thymosin Beta-4. In preclinical models, an influence on cell migration, actin sequestration and neovascularisation has been described. Robust human pharmacokinetic data are not publicly available.
Thymalin
Thymalin is a complex of multiple polypeptides extracted from bovine or calf thymus. Postulated mechanisms include modulation of T-lymphocyte maturation, influence on interleukin profiles and stimulation of cellular immune response. Being a multi-component preparation, individual mechanisms are difficult to disentangle. Khavinson and colleagues from St Petersburg have described the mechanism over decades in Russian publications.

Frequently asked questions
- What is the difference between TB-500 and Thymalin?
- TB-500 is classified as "Заживление", while Thymalin is classified as "Заживление". TB-500: Synthetic fragment of the endogenous protein Thymosin Beta-4, specifically the actin-binding sequence. Preclinical models investigate effects on cell migration, neovascularisation and wound healing — robust human data are absent. Thymalin: Complex of low-molecular polypeptides extracted from calf thymus. Approved in Russia since the 1970s as an immunomodulator. The exact composition is not standardised like a synthetic single peptide; Western controlled studies are largely absent. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, TB-500 or Thymalin?
- The highest available evidence level is "Модель на животных" for TB-500 and "Исследование на людях" for Thymalin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of TB-500 and Thymalin in Germany and the United States?
- Германия: TB-500 — Не одобрено, Thymalin — Не одобрено. США: TB-500 — Только для исследований, Thymalin — Не одобрено. These are factual summaries with source and review date on the individual pages.
