Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide naturally produced by the thymus gland that plays a crucial role in immune system regulation. It is approved in over 30 countries for the treatment of hepatitis B and C, and is extensively researched for immune enhancement in cancer, immunodeficiency, and infectious diseases. Tα1 acts by stimulating T-cell maturation, dendritic cell function, and antibody responses.

Thymosin Alpha-1 is a 28-amino acid peptide naturally produced by the thymus gland that plays a critical role in immune regulation, T-cell maturation, and dendritic cell activation.
Yes, Thymosin Alpha-1 (marketed as Zadaxin) is approved in over 30 countries worldwide for the treatment of hepatitis B, hepatitis C, and as an immune adjuvant.
Our wholesale Thymosin Alpha-1 is manufactured to ≥98% purity, confirmed by HPLC analysis with certificates of analysis included.
Lyophilized Thymosin Alpha-1 should be stored at -20°C for long-term stability. Once reconstituted, store at 2-8°C and use within 14 days.
Thymosin Alpha-1 is studied in immune modulation, viral hepatitis treatment, cancer immunotherapy, vaccine enhancement, and age-related immune decline.
Unlike Thymosin Beta-4 which focuses on tissue repair, Thymosin Alpha-1 is specifically involved in adaptive immune regulation and T-cell function.
