      Frequently Asked Questions

      Is Thymosin Alpha-1 the same as Zadaxin?

      Yes — Zadaxin is the brand name for thymosin alpha-1 (thymalfasin). It is FDA-approved in 35+ countries for hepatitis B, hepatitis C, and as a vaccine adjuvant.

      Can Thymosin Alpha-1 help with long COVID?

      Several small studies and case reports suggest Tα1 may help with long COVID immune dysregulation. Formal clinical trials are ongoing. It is one of the most promising immune-modulating peptides for post-viral syndromes.

      How does Thymosin Alpha-1 differ from Thymosin Beta-4 (TB-500)?

      Thymosin Alpha-1 is primarily immune-modulating (T-cell activation, immune regulation). TB-500 (Thymosin Beta-4) is primarily tissue repair and anti-inflammatory. They are different peptides with different mechanisms and applications.
