Introduction Introduction GHK-Cu ( glycyl-L-histidyl-L-lysine : copper ) is a naturally occurring tripeptide-copper complex commonly known as the copper peptide. First identified in the 1970s, GHK-Cu is present in human plasma, saliva, and urine and has become a major research focus for its potential roles in skin repair, hair growth, wound healing, and tissue regeneration. Preclinical and cosmetic-science studies suggest that GHK-Cu supports collagen synthesis, angiogenesis, and anti-inflammatory and antioxidant responsesmaking it one of the most widely studied peptides in regenerative biology.
