246 listings from 139 vendors, from $0.21/mg. No independent lab tests on record. Prices checked .

Thymosin Alpha-1 is sold for research in many vial sizes and pack counts, so the listings below are ranked by US dollars per milligram rather than sticker price. A low price per mg says nothing about what is in the vial: the lab column shows whether each vendor has passed an independent test, and the methodology explains what a pass means.
