Zinc-Thymulin

The zinc-bound active form of thymulin, a genuine thymic peptide hormone studied in immunology and aging research.

Overview

Thymulin (facteur thymique serique, FTS) is a genuine thymic nonapeptide hormone that requires zinc for its biological activity, and zinc-thymulin refers to this zinc-bound active form. It promotes T-cell differentiation and is studied in immunology and aging research, since serum thymulin activity declines with age. In cosmetic catalogs it is sometimes marketed in hair-related contexts, an application without clinical support.

Mechanism

Thymulin is secreted by thymic epithelial cells and, in its zinc-complexed form, enhances the maturation and function of T lymphocytes. Zinc coordination is essential for receptor binding and biological activity, which is why the peptide is studied together with zinc status.

Expected Effects

  • Improved T-cell maturation markers in experimental systems
  • Thymulin activity is used as a marker of thymic endocrine function
  • An age-related decline in activity is documented in the literature

Side Effects & Tolerability

As a research peptide its systemic safety data are limited. Claims linking zinc-thymulin to hair or cosmetic outcomes are not supported by published clinical evidence.

Storage

Store lyophilized peptide cold and desiccated, protected from light and moisture, per the supplier certificate of analysis.
