04Reading this certificate
This certificate covers one lot. It documents lot GHK100-0803 and no other. Before relying on it, check that the lot number printed on your vial label matches it character for character. A vial from a different lot has its own certificate.
What 99.86% means. Overall purity is measured by reverse-phase HPLC with detection at 214 nm. The figure is the share of the detected signal that belongs to the compound itself; the remainder is everything else the method detected in the sample.
Identity and content are separate checks. Identity was confirmed by LC-MS/MS, which compares the measured mass with the mass expected for the compound. Content is the quantity found in the vial, reported in milligrams, and is why a vial can read slightly above its label strength.
