Introduction

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide that has attracted significant attention in biochemical and dermatological research. Originally identified in human plasma, this peptide is widely studied for its interaction with copper ions and its role in cellular signaling pathways.

In laboratory environments, GHK-Cu is investigated for its involvement in tissue remodeling, cellular communication, and protein synthesis regulation. Due to its broad biological activity, it is commonly explored in research areas such as regenerative biology, skin physiology, and molecular signaling.

It is important to note that GHK-Cu is supplied strictly as a research-use-only compound. It is not approved for human consumption, medical treatment, or cosmetic application outside controlled scientific settings.
