What Is Thymosin Alpha-1?

Thymosin Alpha-1 (Tα1) is a naturally occurring peptide produced by the thymus gland that plays a central role in immune system regulation. It has FDA orphan drug status and is used clinically for immune deficiency conditions. At longevity clinics, it's used for immune modulation, chronic fatigue, post-viral syndromes, and as a general immune-boosting longevity protocol.
