Peptide Lab Testing in Canada: Which Lab Tests Our Batches and How to Verify a COA
Lab testing & verification
Last reviewed 26 September 2026 · Applies to every batch listed on Lab Results
The short version. Every Quantum Peptides batch is tested by Peptide Test Canada, an independent analytical laboratory in Canada, using HPLC for purity and mass spectrometry for identity. The lab issues a batch-coded Certificate of Analysis, we publish it at a permanent URL before the batch is sold, and you can check the report code on the lab’s own website — not just ours. The batch number on the vial matches the batch number on the certificate.
This page explains who the lab is, what the report contains, how to verify one yourself, and how to judge any Canadian supplier’s “lab-tested” claim.
Which peptide lab tests Quantum’s batches?
Peptide Test Canada is a Canadian third-party laboratory that specialises in analytical testing of synthetic research peptides. It is not owned by, affiliated with, or paid on commission by Quantum Peptides — we pay a per-sample testing fee like any other client, and the lab publishes results regardless of what they show.
Two things about this arrangement matter more than the lab’s name:
- Testing happens in Canada. The vial that gets tested is drawn from the same batch that ships to Canadian researchers, with a domestic chain of custody. Several well-known Canadian suppliers use reputable overseas labs (Janoshik in the EU is the most common); that is a legitimate choice, but it means the sample travels a long way from the stock it represents.
- The lab keeps its own public record. Every report carries a code that resolves on the laboratory’s verification portal. A supplier can edit a PDF on its own site; it cannot edit the lab’s database.
What the peptide lab actually tests
| Test | Method | What it tells you | What it can’t tell you |
|---|---|---|---|
| Purity | HPLC (high-performance liquid chromatography) | What percentage of the peptide content is the target sequence vs. related impurities (truncated or deletion sequences, oxidation products). Reported as a percentage — current Quantum batches run 98.5–99.99%. | Whether the peptide is the right peptide. A 99% pure sample of the wrong sequence still reads 99%. |
| Identity | Mass spectrometry (MS) | The measured molecular mass, compared to the theoretical mass of the claimed sequence. Confirms the compound is what the label says. | Sterility, endotoxin load, or how the vial was handled after it left the lab. |
| Batch linkage | Report code + batch number | That this report describes this batch. Quantum vials carry the batch number, manufacturing date and expiry so the physical vial ties back to the certificate. | Anything about a different batch. A COA from June says nothing about a batch made in September — which is why every batch gets its own report. |
Net-weight (mg per vial) and sterility testing are separate analyses and are not part of a standard purity/identity COA from any lab, ours included. Where a supplier’s certificate claims all of these on one page from a single method, ask which instrument produced each figure.
How to verify a Quantum COA yourself (two minutes)
- Read the batch number off the vial label (format
COA-2026-SC-000NN, also printed as a short batch code). - Open Lab Results and find the row with that batch number. The row shows purity, test date, and laboratory, and links the full PDF. Each report also has its own page, so the link you share is permanent.
- Take the report code from the PDF to the laboratory’s verification portal and confirm the record exists there with the same values. If the two don’t match, don’t use the product — and tell us.
How to judge any Canadian supplier’s “lab-tested” claim
Almost every research-peptide site in Canada now says “third-party tested.” The phrase is doing a lot of work. Six questions separate a verifiable claim from a marketing one — they’re the same six we hold ourselves to:
- Is there a Certificate of Analysis at all, and can you open it before you pay?
- What date was the testing done? An undated or year-old certificate is a historical document, not a description of current stock.
- Does the certificate match the batch you’d receive? Look for a batch number on both the report and the product listing.
- Is the batch number, manufacturing date and expiry printed on the vial? Without it, a certificate can’t be tied to the object in your hand.
- Where was the test done — in Canada or abroad? Neither answer is disqualifying; not stating it is.
- Can you view the result on the testing lab’s own website? This is the only step a supplier can’t fake.
As far as we know, Quantum Peptides is the only Canadian supplier that answers all six with “yes, and here’s the link.” If another supplier does too, that’s good for everyone doing research in this country — our source-checked comparison lists what each vendor publicly discloses and marks “not publicly disclosed” where they don’t.
Frequently asked questions
Which lab does Quantum Peptides use?
Peptide Test Canada, an independent Canadian analytical laboratory. Every batch report on our Lab Results page names the lab, the test date and the method.
Is Peptide Test Canada affiliated with Quantum Peptides?
No. We are a fee-paying client. The lab has no financial interest in our results and publishes them regardless of outcome.
What is the difference between HPLC purity and mass-spec identity?
HPLC measures how much of the sample is the target compound versus impurities, as a percentage. Mass spectrometry confirms the molecular mass matches the claimed sequence — that it is the right compound at all. A credible COA reports both.
How do I check a COA is real?
Match the batch number on your vial to the row on our Lab Results page, open the PDF, then check the report code on the laboratory’s own verification portal. The values should agree in all three places.
Why does each batch need its own certificate?
Purity and identity are properties of a specific production run. A certificate describes the batch that was sampled and nothing else. Quantum issues a new batch-coded report for every batch and never overwrites an older one.
Does lab testing mean the peptide is approved for human use?
No. Analytical testing confirms purity and identity of a research reagent. It is not a regulatory authorization. Quantum Peptides products are supplied for in-vitro laboratory research only and are not for human or veterinary use; in Canada, peptides intended for human use are regulated as prescription drugs. See our regulatory guide.
Research use only. Quantum Peptides products are supplied for in-vitro laboratory research and are not for human or veterinary use, diagnosis or treatment. Lab testing describes the purity and identity of a research reagent; it is not a safety assessment or a regulatory approval.
