COA & lab verification
Selected product pages publish public, batch-linked third-party PDF certificates from MDX BioAnalytical Laboratory, Inc. The BPC-157 10mg report was independently opened and reviewed by PeptidePrices: USA COA identifier COA201129, search code 201129, batch 260205BP103, received Feb 10 and reported Feb 11, 2026; identity confirmed as BPC-157, 99.74% purity, 10.14mg determined content against a 10mg label, white-crystal appearance, and endotoxin PASS at a <=0.05 EU/mL threshold, with chromatographic data and a report QR code. This is strong product-level evidence from a named US third-party lab. Coverage is not fully public: BPC-157, GLOW and KLOW pages expose PDFs, while sampled Kisspeptin and GLP-1 pages say the COA is available on request, and /coa is an explanatory/request page rather than a browseable batch library. The vendor claims accredited labs and every-batch testing, but the sampled certificate does not display an accreditation number, and no sterility or heavy-metals result appears on that report. Canadian company at a disclosed Thornhill, Ontario address; legacy puritypeptides.ca redirects to puritypeptides.is. PeptidePrices is an affiliate partner (10% commission + code PEPTIDEPRICES for 15% off); the relationship does not affect the rating.
Our verdict on Purity Peptides
Qualified yes, especially for Canadian buyers. Purity Peptides publishes genuine batch-linked MDX BioAnalytical certificates on selected product pages, and the BPC-157 report we reviewed checks the important basics: identity, 99.74% purity, 10.14mg content, and passing endotoxin. The company also discloses a real Thornhill address and clear Canada-wide shipping terms.
The caveat is consistency of public evidence. Several products expose downloadable PDFs, but others are COA-on-request and the central COA page is informational rather than a browseable report library. Independent reputation is also mixed at 3.6/5 across 31 Trustpilot reviews. Confirm the certificate for the exact batch before ordering; Canadian readers can use code PEPTIDEPRICES for 15% off.
More about Purity Peptides
Purity Peptides is a Canadian research-peptide supplier based at 32 Steeles Avenue W in Thornhill, Ontario. It ships throughout Canada, lists prices in CAD, processes orders in 1–2 business days, and publishes flat-rate regular and express delivery terms. Its catalog is broad — 79 storefront products — and PeptidePrices curated 54 vial-size rows across 34 comparison-ready compounds while excluding sprays, tablets, accessories, and unsupported blends. The imported prices use the July 16, 2026 mid-market rate of 1 CAD = 0.7122 USD before the 15% reader coupon is applied.
The strongest trust signal is the actual lab work on selected product pages. We opened the BPC-157 certificate from MDX BioAnalytical Laboratory and confirmed a batch number, report/search identifiers, 99.74% purity, 10.14mg measured content, an endotoxin pass, and chromatographic data. The limitation is coverage, not the sampled report: BPC-157, GLOW and KLOW expose PDFs, but other sampled products direct buyers to request a COA, and there is no public batch-history library. That evidence earns a strong but not top-tier COA factor. A disclosed address and clear policies help transparency, while a mixed 3.6/31 Trustpilot profile keeps the overall score at 7.5.

Watch-outs
- Public COA coverage is mixed: some product pages link batch PDFs, while other sampled pages say the COA is available only on request; /coa is not a browseable report library
- The sampled MDX report covers identity, purity, net content and endotoxin, but not sterility or heavy metals, and it does not display the lab-accreditation number claimed by the vendor
