GHK-CuCertificate of Analysis

High-Performance Liquid Chromatography (HPLC) is the standard analytical technique used to verify peptide purity. Peptide labs typically run reverse-phase HPLC with UV detection. The chromatogram displays retention time on the x-axis and UV absorbance on the y-axis. The area under each peak corresponds to compound quantity. Purity is calculated as the target peak area divided by total peak area, expressed as a percentage. A purity of 98% or above is the usual research-grade threshold.

Research peptides should be stored lyophilized (freeze-dried) at -20°C or below until ready for use. Avoid repeated freeze-thaw cycles. Upon reconstitution, store at 4°C and use within 30 days. Keep away from direct light and moisture. All handling should be performed under sterile research conditions by qualified personnel following applicable laboratory safety protocols.
