GHK-Cu

GHK-Cu is a naturally occurring copper-binding peptide found in human plasma, with concentrations that decline with age. It has attracted broad research interest due to its ability to influence a wide range of biological processes across multiple tissue types. Research has examined its role in collagen and elastin synthesis, wound healing, anti-inflammatory signaling, and gene regulation related to tissue remodeling. Its capacity to influence expression across multiple biological pathways has made it one of the more versatile peptides in current research, with literature spanning regenerative, dermatological, and cellular biology fields.
