What we found
Purepeptidesuk update, 11 September 2026: the site now says Pure Peptides UK is a trading name of Pure Progress Ltd (Companies House 10512948, Epsom, Surrey). Its batch-lookup site says reports come from 'independent third-party laboratories' and an 'ISO9001 certified' UK partner facility, but it still names no laboratory. The Purepeptidesuk site claims 'Our third-party laboratory is currently experiencing staffing shortages, which has resulted in delays to some batch testing results'. Behind that claim there is no named laboratory and no certificate you can pull up, so a buyer is asked to take the number on trust. Until a lab is named and a report published, the quality claim is unverifiable. A previously recorded 'network' of 8 other ...peptidesuk... domains sharing one Loughborough address has been dropped: that address came only from a fuzzy Companies House keyword match against a company literally named PEPTIDESUK LTD, not from any independent evidence, and directly conflicts with this site's own Pure Progress Ltd/Epsom disclosure. Checked 11 September 2026: the other domains run different WordPress themes with different or no analytics IDs and disclose no shared company, so no real network is currently supported.

Questions people ask about Purepeptidesuk
Is Purepeptidesuk legit?
Purepeptidesuk (purepeptidesuk.com) 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 They claim 'third-party / lab tested' but never name the lab and publish no verifiable certificate, an unnamed, unpublished test is just a marketing claim.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.com 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.
