Thymosin Alpha-1

Thymosin Alpha-1 is a naturally occurring 28-amino-acid peptide originally isolated from thymic tissue and associated with immune-system signaling and regulation. It has been studied in longevity and immunologic research for its relationship to T-cell differentiation, inflammatory signaling pathways, immune resilience, and age-associated immune function across clinical and experimental settings.

Longevity · 10mg · 3mL

Thymosin Alpha-1 is a naturally occurring 28-amino-acid peptide originally isolated from thymic tissue and associated with immune-system signaling and regulation. It has been studied in longevity and immunologic research for its relationship to T-cell differentiation, inflammatory signaling pathways, immune resilience, and age-associated immune function across clinical and experimental settings. Its highly conserved sequence and endogenous origin distinguish it from many structurally modified synthetic peptide analogues. Lyophilized powder, 3mL vial. Sold at 10mg per vial. For research use only.

28-aa acetylated peptide (Thymalfasin). FDA-approved internationally as Zadaxin.
