Buy GHK-Cu peptide — one of the most extensively researched regenerative copper tripeptide complexes available for laboratory investigation. GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide first isolated from human blood plasma in 1973. At PSPeptides, every vial is independently tested at 99%+ purity via HPLC and mass spectrometry, US manufactured, and ships with a batch-specific Certificate of Analysis.
GHK-Cu is a tripeptide-copper(II) complex with the molecular formula C₁₄H₂₃N₅O₄·Cu and molecular weight of 403.93 Da (CAS: 49557-75-7). It exists naturally in human plasma, saliva, and urine — with plasma concentrations averaging ~200 ng/mL at age 20 but declining to ~80 ng/mL by age 60. This age-related decline correlates with decreasing tissue regenerative capacity. To learn more about how GHK-Cu works at the molecular level, see our complete GHK-Cu research guide.
