Thymosin Alpha-1

How It Works

Thymosin Alpha-1 (Tα1) acts on dendritic cells and T-cells to enhance immune surveillance. It stimulates T-cell maturation, increases natural killer cell activity, promotes dendritic cell differentiation, and modulates cytokine production. Uniquely, it balances the immune response — upregulating when needed and preventing overactivation. It activates toll-like receptors (TLR2, TLR9) and stimulates both Th1 and Th2 pathways.

Key Research Findings

• Approved in 30+ countries for hepatitis B/C treatment (as Zadaxin)
• Enhanced vaccine response and immune function in immunocompromised patients
• Studied for adjunctive treatment in various cancers and chronic infections
• Excellent safety profile — does not cause immune overstimulation or autoimmune reactions

Reconstitution Guide

Follow these steps to properly reconstitute Thymosin Alpha-1 for research use:

• Step 1: Swab the tops of both the peptide vial and bacteriostatic water vial with alcohol.
• Step 2: Draw your desired amount of BAC water (commonly 1–2 mL) into an insulin syringe.
• Step 3: Inject the water slowly into the peptide vial, aiming at the glass wall — not directly onto the powder.
• Step 4: Swirl the vial gently until fully dissolved — never shake.
• Step 5: Refrigerate at 36–46°F (2–8°C). Use within 4–6 weeks.
