Is Powerpeptides legit? An independent review
Powerpeptides advertises 'All compounds undergo independent third-party lab testing before release'. 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.

Is Powerpeptides legit? The questions people ask
Is Powerpeptides legit?
Powerpeptides (powerpeptides.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 Powerpeptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. They claim 'third-party / lab tested' but never name the lab and publish no verifiable certificate, an unnamed, unpublished test is just a marketing claim.
How do I check Powerpeptides's certificate myself?
Find the certificate on powerpeptides.co.uk and read four things: an independent laboratory is named; the client field names Powerpeptides, 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.
