Nova Biolabs claims 'HPLC Verified >98%' purity but names no testing laboratory and publishes no certificate of analysis, so there is nothing to check that number against. More telling, it runs a 'Verify Us' page warning buyers about scammers who 'create lookalike profiles' and impersonate the brand, yet it gives no way to verify the actual product: no lab, no COA, no batch check. It manufactures worry about fakes while offering no proof its own vials are what the label claims. It also trades mainly in GLP-1 compounds (tirzepatide, retatrutide, semaglutide) sold as vials and pens. A UK buyer has since reported that an independent Janoshik test of a Nova Biolabs retatrutide 10mg vial came back at only about 2.3mg of active content, roughly a quarter of the labelled dose.
See the full audit. This is the short answer; the full Nova Biolabs dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Nova Biolabs (novabiolabs.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 Nova Biolabs 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. ❌ Don't trust the '>98%' claim. Nova Biolabs stamps 'HPLC Verified >98%' on its products but names no lab and publishes no verifiable certificate; its only 'verification' is a page about avoiding impersonators, not proof
