Cost per mg Calculator
Vial sizes differ from vendor to vendor, which makes a plain sticker-price comparison misleading. This tool converts any vial price into EUR per milligram, so you can compare our vial sizes against each other, or against another vendor's, on equal terms.
How this calculator works
The formula
Price per mg equals the vial price divided by the vial size in milligrams. A 5 mg vial priced at EUR 50 costs EUR 10.00 per mg. A 10 mg vial priced at EUR 80 costs EUR 8.00 per mg, even though its sticker price is higher.
Worked example
Two vials of the same peptide: Vendor A sells a 5 mg vial for EUR 45.00, which is EUR 9.00 per mg. Vendor B sells a 10 mg vial for EUR 70.00, which is EUR 7.00 per mg. Vendor B is the better deal per milligram, even though its vial costs more upfront.
Why price per mg is the fair comparison
Vial sizes are not standardised across vendors, so comparing sticker prices alone favours whoever happens to sell the smallest vial. A bigger vial almost always costs less per milligram, because packaging, shipping and handling do not scale linearly with fill weight. Price per mg removes vial size from the comparison and shows the actual cost of the product, across our own catalogue or against any other vendor. This tool only performs arithmetic on the numbers you enter; it is not a recommendation to buy from any particular source.
