Thymosin Alpha-1
Also known as Tα1, Thymalfasin, Zadaxin.
What it is
Thymosin Alpha-1 is a 28-amino-acid peptide originally isolated from the thymus, the gland that trains immune T-cells. As Zadaxin, it is an approved medicine in roughly 30 countries, but not in the United States or Australia.
That split makes this entry unusual: a compound with established regulatory standing in some countries, and available only through unregulated supply in others.
