Questions people ask about GHK-Cu UK
Is GHK-Cu UK legit?
GHK-Cu UK (ghkcu.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 GHK-Cu UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ GHK-Cu specialist, 'third-party HPLC' but no lab named. ghkcu.uk sells only GHK-Cu copper peptide in the UK, claiming third-party HPLC testing and 'product authentication' but naming no laboratory.
How do I check GHK-Cu UK's certificate myself?
Find the certificate on ghkcu.uk and read four things: an independent laboratory is named; the client field names GHK-Cu UK, 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.
