632 listings from 318 vendors, from $0.0767/mg. 0 of 1 independent lab tests passed. Prices checked .

Built for researchers comparing Semax 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 Semax: PubMed. For research use only; not medical advice.
