🚩 On the watch list, its certificate can't be verified in its own name.
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.
Pricing vs the market, benchmarked on BPC-157
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
The bottom line. Nova Biolabs sits on the watch list because it does not publish a certificate that can be verified in its own name. Everything above is observable on its own website and the public record. See the vendors whose certificates are actually their own →
