GHK-Cu (Copper Peptide)
GHK-Cu (Copper Peptide)
GHK-Cu (Glycyl-L-Histidyl-L-Lysine), also known as the pretty peptide, is a high-affinity copper-binding tripeptide. It is a primary reagent in studies investigating cellular pathways associated with collagen, fibroblast activity, and genomic expression within the extracellular matrix.
For research purposes only
Not for human or veterinary use
Applied in research on collagen-related pathways, fibroblast behaviour, and gene expression
What is GHK-Cu?
What is GHK-Cu?
Test GHK‑Cu, also known as the pretty peptide, is a naturally occurring tripeptide made up of glycine, histidine and lysine, bound to a copper ion [1].
In the human body, this peptide is found in plasma, urine and saliva, but for research purposes, we supply a synthetic, high-purity version. Scientists use it to investigate how copper aids in enzyme function and genomic stability.
Supporting Research and Other Areas of Interest
Dermal Research
GHK-Cu is widely researched for its ability to signal the production of collagen and elastin in skin cells.
In controlled laboratory settings, researchers apply this peptide to skin cells in a dish. The goal is to observe how it influences the extracellular matrix, the structural network that supports the skin. Studies focus on its potential to upregulate Type I collagen and glycosaminoglycans, which are the building blocks responsible for tissue strength and hydration.
Vascular Research
Scientists use GHK-Cu to study angiogenesis, which is the process of forming new blood vessels.
This peptide is tested to see if it can recruit immune cells to a site of injury. The research looks at how GHK-Cu interacts with growth factors like VEGF (Vascular Endothelial Growth Factor) to potentially speed up the repair of damaged tissue and support the flow of nutrients to cells.
Hair Follicle Research
Research into hair biology often utilises GHK-Cu to examine the growth phase of hair follicles.
When studied, investigators look for changes in the size of the follicle and the activity of the dermal papilla cells. The primary interest here is understanding if the peptide can extend the active growth stage and reduce inflammation around the follicle root.
Usage
