EZ Peptides eZ Peptides sells 23+ research peptides 'for advanced laboratory research', dispatched from a UK facility within 24 hours. It states products 'undergo rigorous HPLC testing' and that 'Certificates of Analysis [are] available upon request to verify quality and purity', but no independent laboratory is named and no certificate is published, so there is nothing to check before ordering. No company registration is shown.
See the full audit. This is the short answer; the full EZ Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
EZ Peptides (ezpeptides.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 EZ 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: '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. ⚠ 'Certificates of Analysis available upon request', no lab named. EZ Peptides says its peptides 'undergo rigorous HPLC testing' with COAs on request, but names no laboratory and publishes nothing to verify.
