Questions people ask about UK Peptide Supply
Is UK Peptide Supply legit?
UK Peptide Supply (ukpeptidesupply.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 UK Peptide Supply publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ 'Third-party tested' but no lab, no COAs visible. UK Peptide Supply markets fast UK fulfilment and MT2 but names no laboratory.
How do I check UK Peptide Supply's certificate myself?
Find the certificate on ukpeptidesupply.com and read four things: an independent laboratory is named; the client field names UK Peptide Supply, 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.
