Two listings are compared only when they are the same peptide in the same market, so a 10-vial kit is never set against a single vial. Price per mg is our arithmetic on the listed price, for comparison; the amount you pay is the listed price for the size shown, so check it on the vendor’s own page before you buy. What price per mg means.
No vendor can pay to change a price or the order of anything on this page. Some outbound links are affiliate links.
