GHK-Cu is unusual because it operates as a biological reset signal modulating thousands of genes simultaneously, activating the skin's own repair intelligence rather than forcing a single response

Key Research Benefits: Supports experimental studies on skin repair and collagen synthesis Promotes anti-aging research and tissue regeneration Useful for investigating wound healing and cellular repair mechanisms Lab-tested for high purity, stability, and reproducibility Chemical & Structural Information: Peptide type: GHK-Cu (Copper Tripeptide-1) Form: Lyophilized powder Purity: 99% HPLC verified Storage: -20C recommended for long-term stability Strictly for Research Use Only (RUO) GHK-Cu is intended exclusively for laboratory research and experimental studies

Cell viability for GHK-Cu was previously investigated by Hairui et al, showing no significance difference between the control and the GHK-Cu treated group at the same concentrations and time points, implying the non-cytotoxic nature of GHK-Cu towards HaCaT 11
