Compare up to five vials by what they actually cost per milligram. Enter the mg your COA reports and the cheaper-looking option often isn't the cheaper one.
Vials rarely contain exactly what the label says. A 30 mg vial that tests at 34 mg gives you 13% more peptide than one that tests at 30 mg — which can more than cancel out a higher price.
Enter the quantity from each vendor's certificate of analysis. If you don't have a COA for an option, leave it blank and the label amount is used instead.
