GHK-Cu 1% Serum is a topical research formulation delivering Copper Tripeptide-1 (GHK-Cu) at a 1% active concentration in a precision-designed hydration base. GHK-Cu is a naturally occurring copper-binding tripeptide — Glycyl-L-Histidyl-L-Lysine — with one of the most extensively documented research profiles in cutaneous biology. First identified in human plasma in the 1970s, it has since been studied across wound healing, collagen synthesis, skin remodelling, and antioxidant gene expression.

Unlike the lyophilised injectable vial format, this serum is formulated specifically for transdermal and topical delivery route research. The 1% concentration represents the threshold most commonly referenced in published cutaneous peptide research, suspended in a scientifically composed base of humectants, hydrators, and stabilisers designed to maintain peptide integrity and facilitate skin contact.

Researchers studying buy GHK-Cu serum Europe, topical copper peptide delivery, or cutaneous regeneration will find this formulation suitable for in vitro skin model research, transdermal absorption studies, and comparative delivery format investigations.

GHK-Cu’s biological activity is driven by its copper-chelating tripeptide structure, which interacts with multiple cellular systems relevant to skin biology and wound repair:

Every ingredient in the GHK-Cu 1% Serum is selected for its role in maintaining peptide stability, skin compatibility, and research-grade formulation integrity.

The multi-humectant base (Propanediol + Glycerin + Sorbitol + Sodium PCA) is designed to maintain surface hydration during transdermal research protocols, while Hydroxyethylcellulose provides the gel-serum viscosity profile without synthetic polymers. Panthenol and Beta-Glucan are included as skin-conditioning agents to support barrier integrity during extended application research.
