What we found
Nexapep (nexapep.co.uk, domain registered 21 February 2026) sells research peptides to UK buyers and describes itself as 'Third-Party Verified', with 'HPLC purity analysis', 'MS identity confirmed' and an 'ISO/IEC 17025 independent laboratory'. No laboratory is named anywhere on the site and no certificate is published; the site says a Certificate of Analysis 'is included with every order' and that full documentation is 'available on request'. Its terms say Nexapep Ltd is registered in England and Wales and that its registered office is available on request by email; a Companies House search on 28 September 2026 returned no company of that exact name. The terms also refer to a separate UAE entity. A site at nexapep.com, which the UK site does not link to, publishes certificate images under the same brand. We opened one of its Janoshik reports on Janoshik's own server: task #148977 (BPC-157 10 mg, analysed 14 May 2026) prints the client and manufacturer as Shandong Zhongle Co., Ltd, and the MOTS-c image on the same page, task #148998, shows the same client. A certificate that names the manufacturer as the client shows the factory's sample was tested; it says nothing about the vials a reseller ships.

Questions people ask about Nexapep
Is Nexapep legit?
Nexapep (nexapep.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 Nexapep publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Promises a certificate with every order, publishes none. Nexapep (nexapep.co.uk) says its peptides are third-party verified by an ISO/IEC 17025 laboratory, but names no laboratory and shows no certificate: documentation is 'available on request'.
How do I check Nexapep's certificate myself?
Find the certificate on nexapep.co.uk and read four things: an independent laboratory is named; the client field names Nexapep, 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.
