GHK-Cu Explained: What Researchers Should Know About This Copper Peptide

GHK-Cu, short for glycyl-L-histidyl-L-lysine copper, is one of the most widely discussed peptides in regenerative and cosmetic research. Originally identified in human plasma, this naturally occurring copper-binding peptide has been the subject of scientific investigation for several decades.

Researchers have explored GHK-Cu in a variety of areas, including skin appearance, connective tissue biology, hair research, and cellular signaling. While research continues to evolve, GHK-Cu remains one of the most recognized peptides in the scientific community.

What Is GHK-Cu?

GHK-Cu is a naturally occurring tripeptide composed of three amino acids:

  • Glycine

  • Histidine

  • Lysine

When bound to copper ions, the compound forms GHK-Cu. Researchers believe this copper-binding capability may play a role in many of the biological processes studied in laboratory settings.

The peptide was first identified in human plasma but has also been detected in saliva and urine. Interest in GHK-Cu has grown due to its potential involvement in tissue maintenance and cellular communication.
