GHK-Cu – 100mg

GHK-Cu (Lyophilized) is a tripeptide with a strong affinity for copper ions, studied for its role in collagen-synthesis and wound-healing signaling pathways, along with anti-inflammatory and antioxidant properties. Supplied for laboratory research use only. Not intended for human consumption or topical use.

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) supplied by Peppy Peptides at 99% purity for laboratory research use only. It is one of the most extensively documented copper-peptide complexes in the research literature, valued by investigators for its high-affinity copper-ion coordination chemistry.

What is GHK-Cu?

GHK-Cu is a small tripeptide composed of glycine, histidine, and lysine that forms a stable complex with Cu(II) ions. Structurally, its histidine residue coordinates copper with high affinity, a property that underlies its extensive use as a model compound in copper-biology research. In laboratory settings, GHK-Cu is studied for its interaction with extracellular-matrix signaling pathways, including collagen and glycosaminoglycan synthesis pathways, as well as antioxidant enzyme-signaling cascades associated with copper-dependent enzymatic activity.

Research Applications

In research contexts, GHK-Cu is referenced in laboratory models examining copper-ion transport, extracellular-matrix signaling, and oxidative-stress-response pathways. Investigators studying connective-tissue biology have used GHK-Cu as a reference compound for exploring how copper-peptide complexes interact with matrix metalloproteinase and cytokine-signaling networks in cell-culture and animal-model systems. It is also examined in the context of antioxidant enzyme signaling, including superoxide dismutase pathway activity, within inflammatory-signaling research models. These applications are strictly within controlled laboratory and in-vitro/in-vivo research settings; findings from this literature are not indicative of any approved application in humans or animals.
