Peptides / Semax
Semax
364 listings from 172 vendors, from $0.0767/mg. 0 of 1 independent lab tests passed. Prices checked .
Semax 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. For research use only; not medical advice.
