What we found
Research Peptide (singular, distinct from the separately-listed researchpeptides.co.uk) sells BPC-157, TB-500, MOTS-c, retatrutide and blends as '99% Pure British Peptides,' but its testing is described as '99%+ HPLC purity, full COA available on request,' with no laboratory named and nothing published on the site to verify. 'On request' is not published proof, and the near-identical name to another UK shop is itself a source of confusion buyers should note.

Questions people ask about Research Peptide
Is Research Peptide legit?
Research Peptide (researchpeptide.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 Research Peptide publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ 'COA on request' only, and easily confused with another shop. Research Peptide markets '99%+ HPLC purity' but publishes no certificate on-site (only 'available on request') and names no lab.
How do I check Research Peptide's certificate myself?
Find the certificate on researchpeptide.co.uk and read four things: an independent laboratory is named; the client field names Research Peptide, 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.
