◇ The Peptide Watch, independent vendor audit

Is Nova Biolabs legit? An independent review

novabiolabs.co.uk · audited 30 September 2026

🚩 Nova Biolabs is on the watch list: its certificate can't be verified in its own name, one of 408 of 446 UK sellers that fail this check.

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.

Which UK sellers do pass this check?

Of the 446 active UK sellers The Peptide Watch audits, 38 publish a certificate of analysis you can verify in their own name on the independent laboratory's own website. Ranked by most recent certificate, they are Lab77Peptides, Peptology Labs, Biovanta, Camo Chem, Biohackpeptides and 33 others. This is a record of who publishes verifiable paperwork, not a recommendation.

What doesn't add up on its site

Quoted straight from novabiolabs.co.uk, and why it falls apart.

“…"HPLC Verified >98%" on the products, and on its Verify Us page: "Scammers impersonate legitimate suppliers to steal money. They create lookalike profiles, use similar names..."…”

Nova Biolabs stamps 'HPLC Verified >98%' on its vials and runs a 'Verify Us' page warning buyers about scammers and lookalike sellers, yet it publishes not one certificate of analysis and names no testing laboratory. It manufactures concern about fakes while giving you no way to verify its own product's purity or identity. The warning may be genuine; the proof of what is actually in the vial is entirely missing.

“…Reddit ("Scammed in UK"): "Purchased reta 10mg from Novabiolabs. Received in three days and sent for Janoshik testing. Came back 2.3mg content. Steer clear."…”

A UK buyer publicly reported buying a Retatrutide 10mg vial from Nova Biolabs, sending it for independent Janoshik testing, and getting back about 2.3mg of active content, roughly a quarter of the 10mg on the label. This is a single buyer's report and we have not independently confirmed the test, but it is exactly the outcome an unverifiable '>98%' claim invites: the one time someone tested a vial independently, it came back grossly underdosed. It underlines why a purity or content figure means nothing unless the seller itself publishes a certificate you can verify.

Is Nova Biolabs legit? The questions people ask

Is Nova Biolabs legit?

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.

Can I trust Nova Biolabs, 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 Nova Biolabs publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.

Is Nova Biolabs 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 Nova Biolabs publish a real, verifiable Certificate of Analysis?

Not one that can be independently verified in its own name. 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 of what is in the vial.
