All research →Thymosin Alpha-1 Research Overview
Thymosin Alpha-1 (Tα1; Thymalfasin) is a 28-amino acid N-terminally acetylated thymic peptide — the most rigorously validated member of the thymosin family — with approved status across multiple countries and an evidence base spanning hepatitis B and C treatment, cancer immunoadjuvancy, sepsis immune dysfunction, COVID-19 research, and TLR9-mediated innate immune activation.

Published benefits, side effects, and clinical evidence base for Thymosin Alpha-1 — the immunomodulatory peptide approved in 35+ countries as Zadaxin.
Read article →Thymalin Research Overview
Thymalin is a standardised polypeptide extract of bovine thymus gland studied for T-cell differentiation stimulation, immunosenescence reversal, restoration of thymus-dependent immunity in aged and immunocompromised research models, and its place within a four-decade Russian bioregulatory peptide research tradition demonstrating lifespan extension and immune normalisation effects.

- What is Thymosin Alpha-1?
- Thymosin Alpha-1 (Tα1) is a 28-amino-acid acetylated peptide originally isolated from the thymus. It is widely cited in immunomodulation research for its effects on dendritic cell signalling and T-cell maturation.
- How does Thymosin Alpha-1 differ from Thymalin?
- Tα1 is a single defined peptide; Thymalin is a polypeptide fraction of thymic origin. The Thymalin overview compares mechanism, characterisation and research scope.
- Which signalling pathways are most cited?
- TLR2 and TLR9 activation on dendritic cells, with downstream effects on Th1 cytokine production and T-cell differentiation, are the most frequently cited pathways.
- How is Thymosin Alpha-1 stored?
- Lyophilized Tα1 is stable at 2–8 °C protected from light. After reconstitution, refrigerate and use within the COA's documented window.
