Questions people ask about PEPS IOW
Is PEPS IOW legit?
PEPS IOW (peps-iow.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 PEPS IOW publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. PEPS IOW's tagline is 'third-party tested peptides', but no laboratory is named and no certificate is published anywhere on the site.
How do I check PEPS IOW's certificate myself?
Find the certificate on peps-iow.co.uk and read four things: an independent laboratory is named; the client field names PEPS IOW, 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.
