Mitochondrial peptide studied in metabolic and cellular-energy research.

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-peptide complex. It is studied in collagen production, gene expression, skin remodeling, and antioxidant pathways.
GHK-Cu levels are reported to decline with age. In vitro and in vivo studies examine its effects on gene expression, tissue remodeling, and skin biology using both topical and subcutaneous models.
GHK-Cu appears in injectable, topical, and cell-culture research, and each setting uses different preparation methods. Follow the formulation and handling described in the source paper.
