    Research dossier

    GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine). Research published in the Journal of Biological Chemistry (1988;263(28):14023-14027) identified its copper-binding properties and biological significance. Studies in Wound Repair and Regeneration (2008;16(5):585-601) demonstrated effects on fibroblast gene expression profiles involving over 4,000 genes. Additional research in the International Journal of Molecular Sciences (2018;19(4):1148) examined antioxidant mechanisms and collagen synthesis pathways in dermal cell models.

    Frequently Asked Questions

    For Research Use Only
    Research Use Only: All information below describes in-vitro laboratory findings. GHK-Cu 100mg is not an FDA-approved drug and is not intended for human consumption, therapeutic, or diagnostic use.

    GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) bound 1:1 to a copper(II) ion. Published research has focused on skin fibroblast behavior, extracellular-matrix remodeling, and copper-mediated redox signaling in dermal and wound-healing models.

    The blue tint comes from the copper(II) ion coordinated to the tripeptide — that color is characteristic of Cu²⁺ complexes and is one visual indicator that the copper binding is intact.

    Supplied lyophilized in a sealed vial. Store the unopened vial refrigerated at 2–8°C, protect from light, and reconstitute with bacteriostatic water immediately before use in a laboratory protocol.

    GHK-Cu 100mg (SKU CU100) is independently HPLC and mass-spectrometry tested to 99.2%. A third-party tested Certificate of Analysis is published publicly on this product page — no request required.

    The third-party tested COA for GHK-Cu 100mg is published on this product page. Email email support with your order number if you need the full PDF.
