What is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring copper peptide found in human plasma, saliva, and urine. It is one of the most extensively researched peptides in skincare and anti-aging medicine. GHK-Cu levels decline significantly with age — from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60 — correlating with the visible signs of skin aging.
How It's Made
GHK-Cu is a naturally occurring tripeptide that forms a complex with copper ions (Cu2+). For commercial use, it is synthesized via solid-phase peptide synthesis and then complexed with copper. It is available in topical formulations (serums, creams) and as an injectable.
