Is Nupex legit? An independent review
Nupex trades as Research Scientific Ltd (Companies House 16181281, Christchurch) and states its peptides are 'third-party tested' / 'lab tested' to ≥99% but never names the lab and publishes no verifiable certificate, offering a COA only 'where available' on request. A purity claim with no named lab, no published document and no verification link is just a number on a product page, the buyer is asked to take quality entirely on trust.
"Shopping around" between these names is buying from one seller, same stock, same risk, different branding.

Is Nupex legit? The questions people ask
Is Nupex legit?
Nupex (nupex.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.
Can I trust Nupex, and is it a good supplier?
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Nupex publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
Is Nupex a scam?
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.
Does Nupex publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Nupex (Research Scientific Ltd, Companies House 16181281) claims 'third-party / lab tested' but never names the lab and publishes no verifiable certificate, an unnamed, unpublished test is just a marketing claim.
