Meccanismo d'azione

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 "Guarigione", while Thymalin is classified as "Guarigione". 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 "Modello animale" for TB-500 and "Studio sull'uomo" 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?: Germania: TB-500 — Non approvato, Thymalin — Non approvato. Stati Uniti: TB-500 — Solo ricerca, Thymalin — Non approvato. These are factual summaries with source and review date on the individual pages.
