The spec is three things
GHK-Cu is the copper complex of the tripeptide glycyl-histidyl-lysine (CAS 89030-95-5, ~401.9 g/mol). A trustworthy listing shows identity (it is the copper complex, not the bare peptide), purity (HPLC, with the chromatogram), and a batch number that matches the certificate and the vial.
Copper content is part of identity
Because GHK-Cu is a metal–peptide complex, the copper coordination is part of what makes it that compound. The certificate should confirm the complexed form and record the purity accordingly — a plain peptide purity figure without the copper complex framing is incomplete.
Check the batch by lot number
The strongest check is independent: enter the lot number from the vial and the record returns the certificate, purity and identity for that specific batch. A supplier that only forwards an image cannot demonstrate the document belongs to your vial.

Frequently asked questions
What is the CAS number for GHK-Cu?
The copper complex carries CAS 89030-95-5 with a molecular weight of approximately 401.9 g/mol.
Why is copper content part of identity?
GHK-Cu is a copper-coordinated complex, not the bare tripeptide — the coordination is what makes it GHK-Cu, so the certificate should reflect the complexed form.
