Thymosin Alpha-1
Immunomodulator — Thymic Peptide Thymosin Alpha-1 (Tα1)
A naturally occurring 28-amino-acid peptide derived from the thymus gland, studied for its ability to modulate both innate and adaptive immune responses.
Marketed in over 35 countries as Zadaxin for chronic hepatitis B/C and as an immune adjuvant, it has one of the most extensive clinical safety records of any immunomodulatory peptide.

Thymosin Alpha-1
Mechanism of Action
Thymosin Alpha-1 acts on toll-like receptors (TLR2 and TLR9) on dendritic cells, promoting maturation and antigen presentation. It also enhances T-cell differentiation and modulates cytokine production, giving it a dual role as both an immune stimulant and a regulator that can dampen excessive inflammatory responses.
Balanced Immunomodulation
Unlike simple immune stimulants, Tα1 research shows a balancing effect — boosting immune response in immunocompromised states (chemotherapy, chronic infection) while helping to regulate cytokine storms and autoimmune-type overactivation, a mechanism attributed to its action on regulatory T-cells.
Extensive Clinical History
Approved and marketed as Zadaxin in over 35 countries for chronic hepatitis B and C, and used as an adjuvant alongside vaccines and cancer therapies, Thymosin Alpha-1 has a substantial body of published clinical safety and efficacy data compared to most research peptides.
