What we found
Pure BioLabs (purebiolabs.co.uk, domain registered 19 August 2026) prices in pounds, delivers by Royal Mail and takes enquiries by WhatsApp. Each product page says Certificate of Analysis documentation 'can be provided where applicable to the relevant product batch'; none is published and no laboratory is named. Its returns address is 92 North Street, Hornchurch RM11 1SR. The site states no company, though Companies House lists PUREBIOLABS.CO.UK LTD (17430638), incorporated 1 September 2026 at a different Hornchurch address. It is not Pureline Biolabs, a verified seller in this audit, and it is not the US site purebiolabs.com, which sells peptides described as synthesised in the USA. Checked 28 September 2026.

Questions people ask about Pure BioLabs
Is Pure BioLabs legit?
Pure BioLabs (purebiolabs.co.uk) 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 Pure BioLabs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Certificates on request only. Pure BioLabs (purebiolabs.co.uk) says Certificate of Analysis documentation 'can be provided where applicable', but publishes none and names no laboratory. The domain is six weeks old.
How do I check Pure BioLabs's certificate myself?
Find the certificate on purebiolabs.co.uk and read four things: an independent laboratory is named; the client field names Pure BioLabs, 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.
