How to evaluate a research peptide supplier in Canada
A supplier's claim is useful only when you can check the evidence behind it. Use this checklist to evaluate documents and ordering terms before choosing a research material.
1. Read the original laboratory document
Ask for the report covering the compound, vial size and lot currently offered. Read the issuing laboratory's name, report number, dates, method, results and qualifications. A marketing percentage or a cropped certificate image cannot replace the complete document.
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.

| Check | Evidence to request | Resolve before relying on it |
|---|---|---|
| Material | Compound, molecular form, vial size and lot/reference. | A familiar name alone does not establish the same form or presentation. |
| Report | Complete PDF, report number and issuer's verification record. | A cropped result or supplier screenshot leaves context missing. |
| Sample match | Documentation connecting the tested sample to the offered material. | An assigned reference may differ from the printed vial lot. |
| Test scope | Methods, measurements, dates and qualifications. | Do not infer unreported identity, sterility or endotoxin results. |
| Ordering | Written delivery, payment, support and return terms. | Confirm the delivered total and order reference before paying. |
2. Confirm which sample the result covers
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.
A public report makes scrutiny easier, but publication alone does not connect it to every vial. Ask how the supplier links the tested sample to the material supplied. Keep the correspondence and original document with your procurement records.
3. Separate area purity, content and identity
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.
Check the tests your research requires rather than assuming a high purity figure covers them. The worked example at /library/how-to-read-a-peptide-coa/ explains why area purity and milligrams of measured content answer different questions.
4. Check domestic dispatch and delivery terms
Confirm where parcels physically dispatch from, the carrier, when tracking is provided and whether quoted timing is an estimate. Domestic dispatch avoids an international import leg; it does not guarantee a delivery date. Pure North's ordering guide is at /canada-peptides/, with current terms at /shipping/.
5. Read payment, support and return information
Before transferring funds, check the exact order total, recipient or wallet, order reference and support contact. Read the returns policy and any test-match guarantee in full. Payment method by itself is not evidence of product quality or a seller's reliability.
Pure North accepts Interac e-Transfer and Bitcoin. The confirmation screen supplies the payment instructions for the order. Questions go to purenorthpeptides@proton.me; policy details are at /faq/.
6. Compare like-for-like presentations
Compare the same compound and form, label mass, documentation and delivered total. Price per labelled milligram is the vial price divided by its labelled mass. That arithmetic does not substitute for measured content, and a different molecular form should not be treated as an equivalent solely because its product name is similar.
For example, confirm whether a CJC-1295 listing specifies DAC or No DAC. Pure North stocks the No DAC form. The individual /products/cjc-1295/ and /products/ipamorelin/ listings are separate products, not a blended vial.
Keep claims within the evidence
Research-use wording and a COA are not Health Canada or FDA approval. Neither proves clinical safety. Verify regulatory questions with the relevant authority rather than relying on a supplier's marketing. For laboratory research use only.
Frequently asked
- What should I ask a Canadian peptide supplier before ordering?
- Ask for the original report for the compound, vial size and lot currently offered; the laboratory and methods used; dispatch location; payment instructions; and written support and return terms.
- Does third-party testing mean the supplier did not pay the lab?
- No. An outside laboratory may be commissioned and paid by the supplier. Check the issuer and disclosed relationship. Manufacturer QC should not be described as an independent laboratory report.
- Does a report cover every size of the same peptide?
- No. A report covers its named sample and presentation. Do not apply a result to a different size or lot without documentation establishing the connection.
