3rd party tested.
Thymosin Alpha 1 (Ta1) plays a critical role in boosting immune function. It enhances the activity of T cells, B cells, and dendritic cells, working to coordinate an effective immune response. 
This peptide is especially useful in research associated with compromised immune systems. Tα1 can enhance, modify, and restore immune function. It can stimulate both innate and adaptive immune responses.
Studies have shown that Ta1 has protective effects against oxidative damage. By remarkably amplifying the activity of catalase, superoxide dismutase, and glutathione peroxidase, Ta1 reduces the production of reactive oxygen species and prevents oxidative damage to hepatic tissue.
Ta1 has also shown promise in research associated with treating COVID-19, viral infections (including hepatitis B and C), and can enhance the response to vaccines.
