Quality assurance and testing records

Our published records include supplier-provided COAs alongside independently commissioned laboratory reports. These documents provide different evidence; a supplier COA does not establish that the same sample received the same panel as an independently commissioned report.

Read what each report covers

Check the product, lot identifier, sample description, test date, methods, results and limits shown in the linked document. Do not treat a missing result as a pass. Where an origin COA is unavailable, its record is marked n/a; that does not establish an origin or a testing result.

A published failed result

The published failed GHK-Cu report records cadmium at 1.312 ppm against a 0.5 ppm limit, despite a purity result of 99.65%. Purity alone does not establish compliance with a heavy-metal limit.

The owner states that this rejected GHK-Cu lot was discarded before sale. The laboratory report establishes the measured results; it does not independently prove disposal or the timing of any sale.
