Description

GHK-Cu is a naturally occurring copper-binding peptide composed of the amino acids glycine, histidine, and lysine. It is found in human plasma, saliva, and urine and plays a role in various biological signaling processes. Levels of GHK-Cu naturally decline with age, which has contributed to ongoing research interest in its biological functions.

In research settings, GHK-Cu has been studied for its involvement in cellular communication, tissue remodeling, and gene expression related to repair and regeneration pathways. Its ability to bind copper ions is central to its biological activity, as copper is an essential trace element involved in enzymatic and cellular processes.

GHK-Cu continues to be explored in research environments focused on skin biology, connective tissue signaling, and cellular maintenance, making it a widely referenced peptide in regenerative and longevity-related research.
