Thymosin Alpha-1 (Ta1) is a naturally occurring peptide first isolated from thymic tissue. It is an FDA-approved drug in over 35 countries for hepatitis B and C, and is researched for its immunomodulatory properties including T-cell activation.

The approved dose for Thymosin Alpha-1 is typically 1.6 mg administered subcutaneously twice weekly. Research protocols may vary. This calculator helps determine accurate injection volumes based on your reconstitution.

Reconstituted Thymosin Alpha-1 should be refrigerated at 2-8°C and used within 14-28 days depending on the manufacturer guidelines. The lyophilized powder has a longer shelf life when stored properly.
