Thymosin Alpha-1 Clinics in the United States

What Is Thymosin Alpha-1?

Thymosin Alpha-1 (Ta1) is a 28-amino acid peptide naturally produced by the thymus gland that plays a central role in immune system regulation and function. It declines significantly with age as the thymus involutes.

Ta1 enhances both innate and adaptive immune responses by stimulating T-cell maturation, increasing dendritic cell function, and upregulating immune signaling. It has been used therapeutically in over 35 countries (as Zadaxin) for hepatitis B, hepatitis C, certain cancers, and as an adjuvant for vaccines. In longevity medicine, it is used to reverse age-related immune decline.

It is administered via subcutaneous injection, typically twice weekly.

• Adults with compromised or age-related immune decline
• People pursuing longevity medicine and immune optimization
