What it does

Thymosin Alpha-1 is a 28 amino acid peptide naturally produced by the thymus gland. It modulates T-cell function, enhances dendritic cell activity, increases natural killer cell cytotoxicity, and promotes antibody responses. It acts as a master regulator of the adaptive immune system.

As the thymus gland shrinks with age (thymic involution), natural Thymosin Alpha-1 production declines, making supplementation increasingly relevant for maintaining immune competence.

Dosage & Protocol

Subcutaneous injection. 1.6mg per injection, 2x per week (standard clinical dose from Zadaxin trials). Daily during acute illness. 10 vials provides approximately 12 months.
