Compare peptide costs per labelled milligram
Compare the same molecular form and vial size, then account for documented testing and the delivered total.

Compare the same molecular form and vial size, then account for documented testing and the delivered total.
Use the same denominator
Divide the vial price by its labelled mass to obtain price per labelled milligram. Compare the same compound and molecular form. A smaller sticker price can describe a smaller vial; the vial price alone is not a like-for-like comparison.
Keep measured content separate
Price per labelled milligram is an ordering comparison. It does not establish measured peptide content. When an original report includes measured content, read that result and its qualifications separately from both the label claim and area purity.
For the distinction, see the worked report example.
Compare the delivered total
Review the shipping charge, any applicable taxes and the final confirmed order total. Use the current catalogue for prices and the shipping policy for current terms rather than an old article’s price table.
Account for evidence without inventing a premium
Pure North commissioned Canada Peptide Testing, as a paying client. Published reports cover RP-HPLC-UV area purity and measured content for named samples and vial sizes. They do not include mass-spectrometry identity, endotoxin, sterility or water-content results. Read the original documents at Lab Results.
Different analytical panels answer different questions. Check the actual report rather than assuming a higher price includes identity or endotoxin testing. No universal testing cost or domestic price premium is claimed here.
