GHK-Cu Spray

Research-Documented Benefits

• Collagen & Elastin Synthesis — GHK-Cu stimulates production of collagen types I and III, elastin, and proteoglycans, supporting structural integrity of connective tissue.
• Wound Healing — Demonstrated accelerated wound contraction and re-epithelialization in animal models, with improved tensile strength of healed tissue.
• Gene Expression Modulation — Genome-wide studies show GHK-Cu resets expression of approximately 4,000 human genes toward a healthier pattern, affecting DNA repair, antioxidant, and anti-inflammatory pathways.
• Anti-Inflammatory Action — Reduces pro-inflammatory cytokine levels (IL-6, TNF-alpha) while promoting anti-inflammatory mediators in tissue models.
• Stem Cell Attraction — Research indicates GHK-Cu attracts immune and stem cells to wound sites, enhancing the body's regenerative capacity.

Mechanism of Action

GHK-Cu is a naturally occurring tripeptide (Gly-His-Lys) with high affinity for copper(II) ions. It is found in human plasma, saliva, and urine, with circulating levels declining from ~200 ng/mL at age 20 to ~80 ng/mL by age 60.

Primary Pathways

• Copper Delivery — GHK-Cu delivers bioavailable copper to cells, activating copper-dependent enzymes including lysyl oxidase (collagen/elastin cross-linking), tyrosinase, and superoxide dismutase.
• Gene Expression Reset — Genome-wide analysis shows GHK-Cu modulates expression of approximately 4,000 human genes, shifting patterns toward tissue repair, anti-inflammatory, and anti-oxidant states.
• MMP Modulation — Regulates matrix metalloproteinase activity, promoting controlled extracellular matrix remodeling while preventing excessive tissue degradation.
• TGF-beta Signaling — Activates transforming growth factor beta pathways, stimulating fibroblast proliferation, collagen synthesis, and wound contraction.

GHK-Cu functions as a systemic signaling molecule whose concentrations naturally regulate the balance between tissue damage and repair throughout the lifespan.

Research Protocol Guidelines

All protocols described are for in vitro and in vivo research purposes only. Not for human use.

Reconstitution

Reconstitute lyophilized GHK-Cu with bacteriostatic water or sterile saline. For a 50 mg vial, adding 2 mL yields 25 mg/mL. The reconstituted solution will exhibit a characteristic blue color from the copper complex.

Research Dosing (Preclinical Literature)

• Topical applications: 0.01-1% GHK-Cu in cream or gel vehicles for wound healing and dermal studies
• Subcutaneous: 1-10 mg injected locally at wound sites or systemically in rodent models
• In vitro: 1-100 nM in cell culture for fibroblast, keratinocyte, and gene expression studies
• Iontophoresis: 0.5-2% solutions for transdermal delivery research

Storage

Store lyophilized form at -20°C protected from light. Reconstituted at 2-8°C, use within 14 days. The copper complex is susceptible to oxidation; minimize air exposure in vials.

Safety & Handling Information

For research use only. Not intended for human or veterinary diagnostic or therapeutic use.

Storage Requirements

• Lyophilized: -20°C, desiccated, protected from light and air
• Reconstituted: 2-8°C, use within 14 days
• Minimize oxidation of the copper complex

Preclinical Safety Profile

GHK-Cu is a naturally occurring human peptide with a well-documented safety profile. Topical application studies show no irritation, sensitization, or phototoxicity. Systemic administration in rodent models shows no organ toxicity at standard research concentrations.

Known Considerations

• Copper overload is possible with excessive dosing; monitor copper levels in chronic administration studies
• Gene expression modulation affects ~4,000 genes—consider potential interactions with concurrent gene therapy or expression studies
• Blue-green discoloration of injection sites may occur due to the copper complex

Handling

Standard laboratory PPE. Copper peptide solutions may stain skin and clothing. Dispose of copper-containing waste according to institutional heavy metal waste protocols.
