5mg / Lyophilized *MUST BE RECONSTITUTED* Thymosin Alpha-1 is a potential immune system ally. Also known as Thymosin Alpha, TA1, or T α 1, this fragment of a protein molecule is extensively researched for its role in enhancing immune functions. Derived from Thymosin Fraction 5, it’s a naturally occurring polypeptide with a synthetic counterpart called Thymalfasin. Thymosin Alpha-1 is believed to elevate major histocompatibility complex (MHC) class I, increase cytokine production, and enhance immune responses. Researchers suggest it targets T-helper and cytotoxic T-cell populations, induces cell differentiation, boosts natural killer cell production, stimulates inflammation, and modulates macrophage efficiency and thrombin activity.
