Key Ingredients
Tripeptide-copper complex studied for its ability to modulate over 4,000 human genes. Research demonstrates stimulation of collagen, elastin, and glycosaminoglycan synthesis in dermal tissue.
Discover the researchDescription
GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper complex of the tripeptide Gly-His-Lys bound to a copper(II) ion (Cu2+). Found in human plasma, saliva, and urine, GHK-Cu has been extensively studied for its role in skin remodeling, collagen synthesis, and wound healing.
Research Background
GHK-Cu has a broad evidence base in preclinical research. Studies have demonstrated its ability to stimulate collagen and glycosaminoglycan synthesis, attract immune cells to sites of injury, and modulate gene expression related to tissue remodeling. The nasal spray format enables intranasal delivery research. For research use only.
