GHK-Cu (copper peptide GHK) is a naturally occurring tripeptide-copper complex first isolated from human plasma in the 1970s. Its presence in the body declines with age, which has made it a subject of interest in cellular and tissue biology research — particularly in studies exploring how copper-peptide signaling influences repair and remodeling processes at the cellular level.

Research has investigated GHK-Cu across a wide range of tissue models. Studies have explored its role in fibroblast activity, collagen and elastin synthesis signaling, and matrix metalloproteinase regulation — all relevant to how connective tissue is maintained and remodeled. It's considered one of the more biologically active copper-binding peptides identified in human biology.

In addition to tissue remodeling research, GHK-Cu has been studied in models examining anti-inflammatory signaling, nerve outgrowth, and DNA repair pathway modulation. Its versatile research profile across skin, wound, and nerve tissue models has contributed to a substantial body of published literature on copper peptides in regenerative biology.
