| Test | Result on the certificate | What it measures | This lot |
|---|---|---|---|
| HPLC purity | Not reported | HPLC separates the sample into its components; purity is the share of the detected signal that sits in the main peak. On its own it doesn't show which molecule that peak is. That's what the identity test is for. | Not reported on this certificate |
| Identity (LC-MS) | Mass identified as GHK-Cu · compound named: GHK-Cu · mass identification table: GHK-Cu: 99.719% | Mass spectrometry measures the molecular mass of what's in the vial and compares it with the declared compound. "Confirmed" means the lab found the expected compound. | Reported as matching the declared compound |
| Appearance | Blue Crystal | What the lab recorded before testing: the colour and physical form of the material. | Recorded |
