Thymosin Alpha-1 (5mg)

Thymosin Alpha-1 (Tα1, 5mg) is a naturally occurring 28-amino acid peptide derived from prothymosin alpha — a 113-amino acid precursor protein expressed in thymic tissue. First isolated from bovine thymus by Allan Goldstein at the Albert Einstein College of Medicine in 1977, it is one of the most clinically documented research peptides in immunology, with regulatory approval under the brand name Zadaxin (thymalfasin) in over 35 countries and a published clinical evidence base spanning four decades. It is studied in laboratory settings for toll-like receptor signaling, dendritic cell activation, T-cell differentiation, and immune modulation research. Manufactured in a cGMP-certified US facility. Independently third-party tested for HPLC purity, mass spectrometry identity, endotoxin, and sterility. For laboratory research use only.
