Research & Education
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Plasma levels of GHK-Cu decline significantly with age (from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60), and this decline correlates with reduced regenerative capacity. GHK-Cu is one of the most extensively studied peptides for skin rejuvenation, wound healing, and anti-aging applications. It has the remarkable ability to reset gene expression patterns in aged tissue toward a healthier, younger profile. Beyond cosmetic applications, GHK-Cu promotes tissue remodeling, reduces inflammation, and supports overall connective tissue health.
