What we found
Aminopeptides advertises 'Every batch undergoes rigorous, independent third-party testing to guarantee identity, purity, and stability'. It names no testing laboratory and publishes no certificate to look at, so that claim cannot be traced back to anyone. Until a lab is named and a report published, the quality claim is unverifiable.

Questions people ask about Aminopeptides
Is Aminopeptides legit?
Aminopeptides (aminopeptides.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 Aminopeptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. The 'View COA' buttons are dead placeholders or the COA page is empty, they advertise certificates that don't actually exist.
How do I check Aminopeptides's certificate myself?
Find the certificate on aminopeptides.co.uk and read four things: an independent laboratory is named; the client field names Aminopeptides, 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.
