Research Peptide 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.
See the full audit. This is the short answer; the full Research Peptide dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
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.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Research Peptide publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: 'coa on request', nothing published. Being unverifiable is a reason for caution, not proof of fraud.
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.
