What we found
Bionexis Peptides ('UK Laboratory') sells a broad range and claims 'HPLC & LC-MS verified, COA per batch, ≥99% purity,' but names no laboratory and shows no company details on its homepage. Domain registered January 2026. Until it publishes an own-name certificate from a named independent lab you can verify, the purity figure is its own word.

Questions people ask about Bionexis Peptides
Is Bionexis Peptides legit?
Bionexis Peptides (bionexispeptides.com) 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 Bionexis Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ HPLC/LC-MS claimed, no lab named. Bionexis Peptides advertises 'COA per batch' and '≥99% purity' but names no testing laboratory, so there's nothing to verify.
How do I check Bionexis Peptides's certificate myself?
Find the certificate on bionexispeptides.com and read four things: an independent laboratory is named; the client field names Bionexis Peptides, 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.
