GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring tripeptide-copper complex with the amino acid sequence Gly-His-Lys that demonstrates extraordinary regenerative, protective, and anti-aging properties across multiple tissue types and biological systems.
GHK-Cu has been shown to regulate over 4,000 genes — resetting expression patterns toward a healthier profile. It modulates metalloproteinases, stimulates collagen synthesis, and promotes antioxidant enzyme production. Research areas include extracellular matrix remodeling, wound healing, skin biology, and anti-inflammatory signaling.
Purity: Over 99%, HPLC-tested
Form: Lyophilized peptide (powder)
Sequence: Glycyl-L-Histidyl-L-Lysine + Cu²⁺
Packaging: Sealed glass vial, sterile handling recommended
Origin: Pharmaceutical-grade peptide synthesis
