GHK-Cu is a naturally occurring copper peptide found in human plasma. Its concentration declines with age. It functions as a signaling molecule that can stimulate collagen production, promote dermal fibroblast activity, and modulate inflammatory responses. The copper ion is essential for its biological activity.
