GHK-Cu – Research-Grade Copper Peptide | 100 mg | Liquilabs Certified

GHK-Cu (Glycine-Histidine-Lysine-Copper) is one of the most extensively researched copper-binding tripeptides in modern biomedical science. For researchers sourcing GHK-Cu in the Netherlands, batch RGXGHKCU100-2602-01 delivers 100 mg at >99.8% purity — with a perfect identity match score of 1.000 confirmed by Liquilabs.

What is GHK-Cu?

GHK-Cu is a naturally occurring copper complex composed of the tripeptide GHK bound to a copper(II) ion. First identified in human plasma, it has since become one of the most cited peptides in cellular biology, skin science, and wound healing research. Its interaction with a remarkably broad array of biological pathways has generated hundreds of peer-reviewed studies.

Research applications include:

• Wound healing and skin repair cell model studies
• Fibroblast proliferation and collagen synthesis research
• Antioxidant enzyme upregulation (SOD, catalase) studies
• Gene expression modulation — over 4,000 genes influenced in research models
• Hair follicle biology and keratinocyte research
• Anti-inflammatory and tissue remodeling pathway studies
• Neuronal repair and neuroprotection research models
