Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide naturally produced by the thymus gland, where it plays a
central role in T-cell maturation, differentiation, and immune regulation. It is one of the most clinically studied
immunomodulatory peptides, with approval in over 35 countries for the treatment of hepatitis B, hepatitis C,
and various immune deficiencies. It is increasingly used in integrative medicine for immune optimization,
chronic infection, cancer adjunct therapy, and post-viral recovery.
