Laboratory notes
Identity confirmed as GHK-Cu by LC-MS. Chromatographic purity is the main-peak share of total integrated peak area by reversed-phase HPLC with UV detection. Two vials were measured: purity 99.40% and 99.42%, net peptide content 59.54 mg and 57.61 mg against a 50 mg label claim, a fill accuracy of up to 119.1%. Results relate only to the sample as received.
