GHK-Cu

Description

GHK-Cu (Glycine-Histidine-Lysine-Copper) is a naturally occurring tripeptide-copper complex found endogenously in human plasma, saliva, and urine. Supplied as a purified lyophilized powder in sealed vials of 50mg and 100mg, each lot is independently tested via HPLC/UPLC-MS for purity at 99%+ with accompanying bacterial endotoxin documentation. The lyophilized form is stable when stored in cool, dry conditions away from direct light; following reconstitution, refrigeration at 2–8 °C is recommended to maintain analytical quality.

GHK-Cu has been one of the most extensively characterized copper-binding peptides in the biomedical literature, with laboratory studies examining its capacity to stimulate collagen and glycosaminoglycan synthesis, activate matrix metalloproteinase remodeling enzymes, upregulate antioxidant and anti-inflammatory gene networks, and promote wound contraction and re-epithelialization in model systems. Its ability to modulate over 4,000 human genes, as documented in transcriptomic studies, has positioned it as a reference compound for researchers studying skin biology, cellular senescence, DNA repair mechanisms, and systemic aging-associated tissue decline.
