Nexus Peptides nexus Peptides (matching Nexus Peptides Ltd, Companies House 16987354) sells retatrutide and tirzepatide pens, IGF1-LR3, MT-2 and MOTS-c with GBP pricing and a 'COA's' header, but names no laboratory and publishes no verifiable certificate.
See the full audit. This is the short answer; the full Nexus Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Nexus Peptides (nexuspeptides.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 Nexus 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. ⚠ Registered UK company (name match), mentions COAs but no lab named. Nexus Peptides Ltd (Companies House 16987354) mentions COAs but names no laboratory.
