Manchester Peptides manchester Peptides sells research-peptide vials with GBP pricing, free UK shipping and same-day dispatch before 2pm, branding itself 'COA Verified Research Peptides UK' with '99.1% HPLC-tested purity across every batch', but names no laboratory and shows no company details. Its own HPLC number is not third-party verification.
See the full audit. This is the short answer; the full Manchester Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Manchester Peptides (manchesterpeptides.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.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Manchester Peptides 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: no named lab, nothing to verify. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ⚠ 'COA Verified, 99.1% HPLC' but no lab named. Manchester Peptides brands itself 'COA Verified' with same-day UK dispatch but names no independent laboratory.
