How we read the certificate

Its certificate is its own. Peptifyuk publishes its own Janoshik certificate of analysis, naming Peptifyuk as the client, with its most recent certificate dated May 2026. Because Janoshik reports carry a unique code checkable on janoshik.com, the result can be independently verified.

Verify this certificate on Janoshik’s own site →

Opens the report on janoshik.com. Confirm the Client field names Peptifyuk and the purity matches. This is exactly the check we ran.

Google Ads

Note: this seller also runs Google ads for research peptides, a category Google's own policies prohibit, visible in Google's Ads Transparency Centre (UK). Worth knowing, but it doesn't bear on the question that puts it on the independently-tested list: its certificates are its own and genuine.

Peptifyuk reviews: what others report

Third-party signals we found, reviews, independent tests and platform actions, each attributed to its source and labelled by how well it is corroborated. This is not our own verification; items marked "single / unverified report" are unconfirmed and should be treated with caution.

reported

The vendor is stated to be PEPTIFY LIMITED, Companies House #17021295, registered at 21 Harewood Drive, Ilford; a registered UK company, though this is largely the vendor's own disclosure and does not itself attest to product quality.

Questions people ask about Peptifyuk

Is Peptifyuk legit?

On The Peptide Watch's independent audit, Peptifyuk (peptifyuk.com) publishes its own verifiable Janoshik certificate of analysis that names Peptifyuk 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 Peptifyuk 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 Peptifyuk's certificate myself?

Find the certificate on peptifyuk.com and read four things: an independent laboratory is named; the client field names Peptifyuk, 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.
