Melanotan II

160 listings from 119 vendors, from $0.38/mg. 22 of 39 independent lab tests passed. Prices checked .

Melanotan II 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.
