About Thymosin Alpha 1

Thymosin Alpha 1 (Tα1) is an immune-modulating peptide naturally produced by the thymus gland. It's the master regulator of immune function, enhancing T-cell production and maturation, boosting natural killer cell activity, and modulating dendritic cells. FDA orphan drug status for hepatitis B. Approved in over 30 countries for hepatitis and as an immune adjuvant. It balances the immune system rather than just boosting it.
