Thymosin Alpha-1

Thymosin Alpha-1 (Tα1, 28-amino-acid thymic peptide)

Thymosin Alpha-1 is a 28-amino-acid peptide first isolated from the thymus, the small gland behind the breastbone where immune cells learn to recognise friend from foe. The body produces it naturally, and it has been studied for decades as a regulator that helps the immune system find its balance — calming it when overactive, supporting it when underperforming. It is among the most extensively researched immune peptides, examined in thousands of individuals across viral, immune, and oncology settings.
