A copper-binding tripeptide that's been studied for decades in skin biology and tissue-repair research.

GHK-Cu is a tiny three-amino-acid peptide (just glycine-histidine-lysine) bound to a copper ion. It's one of the most extensively studied tripeptides in the lab. The peptide naturally grabs copper, and most of the published research is on what that copper-loaded form does in cell-culture and animal-model skin and tissue research.
How it's been studied: Microarray and gene-expression studies have shown GHK-Cu can shift the activity of hundreds of genes related to wound repair and tissue remodeling in cultured cells. Research has examined effects on fibroblast growth, collagen and elastin production, and copper-dependent antioxidant enzymes.
Where you'll see it in research:
Handling notes: The copper-bound form is bright blue in solution. Avoid mixing with strong reducing agents that could pull the copper off.
Every batch is third-party tested for purity, identity, and contaminants. Download the COA for the lot you receive.
