Questions people ask about PS Labs
Is PS Labs legit?
PS Labs (pslabs.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 PS Labs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. PS Labs says its peptides are third-party tested, but its research library names no laboratory and publishes no report.
How do I check PS Labs's certificate myself?
Find the certificate on pslabs.uk and read four things: an independent laboratory is named; the client field names PS Labs, 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.
