What Is GHK-Cu?
GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Plasma concentrations of free GHK decline significantly with age, a finding that has driven substantial research interest in its role in tissue maintenance and regeneration. The tripeptide binds copper(II) with high affinity via coordinated interactions at the imidazole nitrogen of histidine and the N-terminal amines of glycine and lysine.
Preclinical research has studied GHK-Cu across wound healing models, collagen I and III synthesis, elastin production, matrix metalloproteinase (MMP) regulation, angiogenesis, anti-inflammatory pathways (NF-ฮบB inhibition), and antioxidant superoxide dismutase (SOD) activity. Its copper-transport function is also studied in relation to copper-dependent enzyme activity. GHK-Cu is frequently used in comparative tissue repair research alongside BPC-157.
For tissue repair research via VEGF/eNOS pathways, see BPC-157 and TB-500. For research use only.
