What is GHK-Cu?
GHK is the sequence of three amino acids (glycine-histidine-lysine) with high affinity for copper; when it binds this ion it forms the GHK-Cu complex. That ability to carry and release copper is central to many of the processes studied with it.
Research context
In vitro and preclinical research on GHK-Cu has focused on extracellular matrix remodeling, wound healing and cosmetic applications related to the skin.
These studies are investigational in nature and do not constitute claims of efficacy in humans. GHK-Cu is offered for research use only.
