THE IMMUNE RESTORER

A-3 Peptide; Thymic Bioregulator

Thymagen is a thymus-derived bioregulator peptide that helps restore immune balance. It promotes T-cell differentiation, modulates inflammatory responses, and enhances antioxidant defenses. It's used to restore immune competence after chronic infections, stress, or aging, helping to reverse the immune decline (immunosenescence) that occurs as we get older.
