Peptidesoflondon's certificate is signed off on the seller's own quality form by a single named 'head of laboratory', that's internal QA wearing a lab coat, not an independent lab.
See the full audit. This is the short answer; the full Peptidesoflondon dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Peptidesoflondon (peptidesoflondon.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 Peptidesoflondon 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: own qms 'head of lab'. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ❌ Don't trust their 'COA' as equal to Janoshik. Their testing is Martin Barnard BSc/QMS, a one-named 'head of laboratory' on their own QMS form, not a recognised independent lab.
