What we found
Purepeptidesuk states its peptides are 'third-party tested' / 'lab tested' to ≥99% but never names the lab and publishes no verifiable certificate. A purity claim with no lab, no document and no verification link is just a number on a product page, the buyer is asked to take quality entirely on trust.

Questions people ask about Purepeptidesuk
Is Purepeptidesuk legit?
Purepeptidesuk (purepeptidesuk.net) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
Does Purepeptidesuk publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. They claim 'third-party / lab tested' but never name the lab and publish no verifiable certificate, an unnamed, unpublished test is just a marketing claim.
How do I check Purepeptidesuk's certificate myself?
Find the certificate on purepeptidesuk.net and read four things: an independent laboratory is named; the client field names Purepeptidesuk, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
