What we found
Neoviapeptides's product pages read 'Each COA is produced by independent HPLC-MS testing and confirms purity (≥99%), mass spectrometry results and sequence identity'. The certificate on display names a different company as the client, so it belongs to a supplier's sample rather than this seller's stock. Testing paid for by a supplier says nothing checkable about this seller's own stock. The client printed on that certificate is liyudaily.com (a Chinese factory), not Neoviapeptides.

Questions people ask about Neoviapeptides
Is Neoviapeptides legit?
Neoviapeptides (neoviapeptides.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 Neoviapeptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. The Janoshik certificate is real, but the client on it is liyudaily.com (a Chinese supplier), NOT them. They've never tested their own stock; they're displaying someone else's certificate, which proves nothing about the vial they'll send you.
How do I check Neoviapeptides's certificate myself?
Find the certificate on neoviapeptides.co.uk and read four things: an independent laboratory is named; the client field names Neoviapeptides, 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.
