GHK-Cu (Glycyl-L-Histidyl-L-Lysine – Copper Complex) is the most studied anti-aging copper peptide, naturally present in human plasma at ∼200ng/mL and released from ECM after injury. It is the only peptide with a distinct blue color due to Cu2+ chelation, making it instantly recognizable. Unlike BPC-157 (gut/tendon) and TB-500 (actin migration), GHK-Cu is specialized for skin regeneration, hair follicle stimulation, and extracellular matrix remodeling. It is the top trending compound for skin aging and wrinkle reduction, hair thinning and follicle miniaturization, scar remodeling and wound healing, and aesthetic clinic anti-aging protocols.
GHK-Cu repairs through four synergistic cellular mechanisms. 1. GHK-Cu Binding & Cellular Uptake: Binds cell surface receptors, delivers copper into fibroblast, natural tripeptide from ECM after injury. 2. Fibroblast Activation & ECM Synthesis: Activates fibroblast → ↑Collagen Synthesis Type I & III, ↑Elastin Synthesis (elastin & decorin), ↑Glycosaminoglycans (hyaluronic acid & proteoglycans) → improved skin structure, elasticity, tensile strength. 3. Anti-Inflammatory & Antioxidant Action: ↓TNF-α, TGF-β, IL-6, NF-κB signaling, suppresses chronic inflammation & cytokine release, ↑Antioxidant Defense SOD, Catalase, Glutathione peroxidase, neutralizes ROS/free radicals, protects against oxidative stress. 4. Skin Remodeling & Repair: ↑Angiogenesis VEGF & BDNF new blood vessel formation, ↑Remodeling balanced MMPs & TIMPs → healthy tissue remodeling, ↑Wound healing faster repair reduced scarring. Outcome: Skin regeneration, reduced fine lines, improved elasticity, firmer more youthful skin. Mechanism based on clinical research at picomolar-nanomolar concentrations.
Our GHK-Cu lineup is supplied as high-purity lyophilized powder (>99% HPLC) with distinctive blue hue after reconstitution. For standard research, GHK-Cu 50mg (most requested), GHK-Cu 100mg (high-dose), and GHK-Cu 200mg (value bulk) are available. For synergistic skin/hair protocols, GHK-Cu 50mg + TB-500 10mg Blend is popular for combined collagen and angiogenesis activation. GHK-Cu belongs to Repair & Anti-Aging Peptides category alongside BPC-157 and TB-500, but is the only copper-dependent peptide requiring blue solution handling. Stable 24 months at -20°C. For Research Use Only, not for human consumption.
