How we read the certificate
Questions people ask about Peptideprime
Is Peptideprime legit?
On The Peptide Watch's independent audit, Peptideprime (peptideprime.co.uk) publishes its own verifiable Janoshik certificate of analysis that names Peptideprime itself as the client, so its testing can be checked on Janoshik's own website. That is the strongest evidence standard we track. It confirms the credibility of the seller's evidence, not any individual vial you receive.
Does Peptideprime publish a real Certificate of Analysis?
Yes. Its most recent own-name Janoshik certificate is dated May 2026 and can be verified on Janoshik's website by its unique code, so the purity result cannot be faked or edited.
How do I check Peptideprime's certificate myself?
Find the certificate on peptideprime.co.uk and read four things: an independent laboratory is named; the client field names Peptideprime, 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.
