What we found

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.

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.

Questions people ask about Nova Biolabs

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.

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.

How do I check Nova Biolabs's certificate myself?

Find the certificate on novabiolabs.co.uk and read four things: an independent laboratory is named; the client field names Nova Biolabs, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
