What we found
North Peptides UK checked 29 September 2026: northpeptidesuk.com ('Est. 2025') is a live UK storefront selling retatrutide (10 to 50mg), tirzepatide, pen kits, GHK-Cu and BPC-157 in GBP with Royal Mail Tracked 48 and UK stock claims, contactable by Telegram and WhatsApp. Its testing copy names 'Analiza Białek sp. z o.o., Wrocław' and quotes two verification codes, 2W78KU6M for retatrutide and 1W6J3DY2 for GHK-Cu, dated 30 July 2026; the tirzepatide listing instead says 'supplier documentation available on request'. No UK company registration is stated anywhere on the site. The codes were not run against any lab portal this session (Analiza Białek has no public verification page found), so the claim is recorded but unverified. What would move this listing: a working, checkable verification route for the quoted codes, or a UK company registration.

Questions people ask about North Peptides UK
Is North Peptides UK legit?
North Peptides UK (northpeptidesuk.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 North Peptides UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. North Peptides UK (northpeptidesuk.com) names a real laboratory, Analiza Białek sp. z o.o. of Wrocław, Poland, with verification codes on two products, but this audit has no way to check those codes against an independent portal the way a Janoshik key can be checked.
How do I check North Peptides UK's certificate myself?
Find the certificate on northpeptidesuk.com and read four things: an independent laboratory is named; the client field names North Peptides UK, 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.
