654 listings from 148 vendors, from $0.15/mg. 34 of 60 independent lab tests passed. Prices checked .

Built for researchers comparing Semaglutide vendors before they buy. It 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. Published research on Semaglutide: PubMed. For research use only; not medical advice.
