Price per verified mg

A cheaper vial is not cheaper if it holds less. Enter what each option costs and its label amount. If a test record gives the measured amount and HPLC purity, add them to see the cost per verified milligram.

Verified milligrams are the measured amount multiplied by HPLC purity. This compares cost only. It says nothing about how any product is used.

How this works

Cost per labelled milligram divides the price by the amount printed on the label. It is the number most buyers compare, and it assumes the label is right. Cost per verified milligram divides the price by what was actually measured: the measured amount multiplied by HPLC purity, so it counts only the target peptide.

FIG 13Amount against the label

Three vials with a dashed label line: one measuring under the line, one on it, one over it, labelled underfilled, on label and overfilled.

The two can differ a lot. A vial filled below its label, or one with lower purity, costs more per real milligram than its price suggests, which is why the Tested Index penalises underfilling. Use the record picker to fill measured values from any public Tested.ph record, then share the comparison with the link: it carries prices and labels only, never anything about you.
