Yes — a Certificate of Analysis is published for GHK-Cu. A Certificate of Analysis reports what one laboratory measured in one submitted sample on the test date shown on the report.

Laboratory

Janoshik Analytical

Report number

196358

Test date

26 June 2026

Measured result

99.95% purity (as reported)

Sale lot

Sale lot not stated

The public record does not state which sale lot that sample came from, so a certificate shows the measured result for the sample analysed, not the composition of a particular vial or order. An earlier certificate stays on file after a newer one is published; it describes the sample analysed on its own test date.

Where a report states a purity, the method and any identity result are on the report itself. A purity figure on its own does not confirm identity, sterility, endotoxin content or any biological property. See how to read a Certificate of Analysis and what a COA cannot tell you.

Certificates on this page are issued by independent third-party laboratories (the report names which). Questions about a certificate? Email hello@new-u.io with your order reference. For laboratory research use only ; not for human consumption.
