Know what the report covers.

See who performed the testing, which sample was submitted and what was measured. The original report is the starting point.

1. Step 01

   Start with the published report.

   Pure North commissioned Canada Peptide Testing, as a paying client, and publishes 13 independent reports at /lab-results/. Each report covers only its named sample, vial size and lot or assigned reference. Manufacturer QC documents may be available on request for other peptide lots; they are not independent reports. Selank, Semax and Tirzepatide COAs are temporarily unavailable. Bacteriostatic water has no COA.

2. Step 02

   Match the sample and presentation.

   Match the compound, vial size and printed lot to the report before relying on it. An assigned reference is not automatically the batch code on a vial. If they differ, email purenorthpeptides@proton.me with the vial details and report number to confirm the connection. Do not extend a report to another size or lot.

3. Step 03

   Read purity and content separately.

   Area purity is the target peak's share of the chromatographic response. Measured content is reported in milligrams against a working standard. High area purity does not guarantee that the measured content matches the label claim.

4. Step 04

   Check the limits of the testing.

   The published Canada Peptide Testing reports measure RP-HPLC-UV area purity and content. They do not include mass-spectrometry identity, endotoxin, water content or a related-substances breakdown. These results do not establish clinical safety or regulatory approval.

5. Step 05

   Keep the original document.

   Use the full PDF and laboratory verification link. Keep the report number with your vial and procurement records, including any clarification of the lot or assigned reference.

6. Step 06

   Review delivery and payment.

   Orders dispatch from Canada with Canada Post Xpresspost tracking. Read the current shipping terms and follow the payment instructions supplied with your order confirmation.

The published Canada Peptide Testing reports measure RP-HPLC-UV area purity and content. They do not include mass-spectrometry identity, endotoxin, water content or a related-substances breakdown. These results do not establish clinical safety or regulatory approval.
