What is GHK-Cu 200mg (Copper Peptide) (Topical)

GHK-Cu 200mg (Copper Peptide) (Topical) is a naturally occurring matrikine peptide complex consisting of the tripeptide Glycyl-Histidyl-Lysine (GHK) complexed with divalent copper (Cu²⁺). First isolated from human plasma albumin in 1973, GHK-Cu is one of the most extensively studied peptides in dermal matrix biology.

The GHK tripeptide sequence is found in collagen and is released during tissue injury and remodeling. When complexed with copper, the peptide takes on its bioactive conformation, enabling it to interact with specific cell surface receptors and transcription factors. Unlike unconjugated GHK, the copper-bound form (GHK-Cu) exhibits significantly enhanced biological activity, particularly in studies involving fibroblast proliferation, collagen synthesis, and tissue remodeling.

Researchers purchase GHK-Cu 200mg (Copper Peptide) (Topical) for studies involving dermal matrix remodeling, wound healing mechanisms, fibroblast activation, and extracellular matrix homeostasis. The copper ion is essential for the peptide’s biological activity, particularly for lysyl oxidase (LOX) activation, which cross-links collagen fibrils. This compound is strictly supplied as a lyophilized powder for reconstitution and is for research purposes only.

Product Specifications Table

How It Works

GHK-Cu (Glycyl-Histidyl-Lysine-Copper) is a naturally occurring matrikine peptide that functions through multiple coordinated mechanisms involving copper-dependent signaling, gene expression modulation, and enzyme activation. The mechanism of action involves five key stages:

1. Copper Coordination and Stability:

The GHK tripeptide binds Cu²⁺ through three coordination sites:

• The N-terminal amino group (Gly)

• The imidazole nitrogen of histidine (His)

• The deprotonated amide nitrogen between Gly and His

This square-planar coordination complex creates a stable bioactive conformation. The copper ion is essential for biological activity – GHK without copper (apo-GHK) has significantly reduced activity. The peptide acts as a natural copper delivery system, protecting the metal ion from redox cycling that would otherwise generate ROS.

2. Cell Surface Receptor Binding and Internalization:

GHK-Cu binds to specific cell surface receptors with moderate affinity (Kd ~1-10 µM). The peptide complex is then internalized via endocytosis, delivering copper to intracellular compartments. Receptors implicated in GHK-Cu signaling include:

• Integrins (α5β1, αvβ3) – involved in ECM signaling

• 140 kDa GHK-binding protein (identified in fibroblast membranes)

• Endocytosis pathways (clathrin-mediated and caveolar)

3. Intracellular Copper Delivery and Lysyl Oxidase Activation:

Once internalized, GHK-Cu provides bioavailable copper for cuproenzymes, particularly:

• Lysyl oxidase (LOX): A copper-dependent enzyme that cross-links collagen and elastin fibers. LOX catalyzes the oxidative deamination of lysine residues, forming aldehydes that spontaneously react to form covalent cross-links. This is essential for tensile strength of connective tissue.

• Superoxide dismutase (SOD1): Copper-zinc SOD protects cells from oxidative stress.

• Cytochrome c oxidase (COX): Involved in mitochondrial respiration.

4. Transcription Factor Modulation (Gene Expression):

GHK-Cu directly affects transcription factor binding to DNA, particularly:

• NF-κB (Nuclear Factor kappa-light-chain-enhancer of activated B cells): GHK-Cu inhibits NF-κB nuclear translocation, reducing pro-inflammatory cytokine expression (TNF-α, IL-1β, IL-6, IL-8).

• AP-1 (Activator Protein 1): Modulates collagenase (MMP-1) expression.

• Sp1 (Specificity Protein 1): Upregulates collagen and other ECM genes.

• p53: May influence cell cycle regulation.

Gene expression studies show GHK-Cu affects over 4,000 genes (upregulates ~2,300, downregulates ~1,700), including:

5. Downstream Biological Effects:

The net effect of GHK-Cu in research models includes:

Research Advantages:

GHK-Cu is unique among matrikine peptides because it incorporates a biologically active metal ion. The copper is essential for lysyl oxidase activation, which is the only enzyme capable of cross-linking collagen and elastin. Without copper, newly synthesized collagen fibers lack tensile strength. This makes GHK-Cu particularly valuable for studies involving:

• Mechanical properties of healing tissue

• Extracellular matrix stabilization

• Copper-dependent enzyme mechanisms

Researchers order GHK-Cu online USA to leverage these multi-target mechanisms for extracellular matrix and wound healing research.

📦 Storage Instructions

Proper storage of GHK-Cu 200mg (Copper Peptide) (Topical) ensures maximum stability for your research:

1. Store at -20°C for long-term stability:

Unopened vials remain stable for 24 months in a non-frost-free laboratory freezer. Do NOT store in a self-defrosting (auto-defrost) freezer as temperature fluctuations during defrost cycles cause peptide aggregation. The copper complex remains stable under these conditions.

2. Refrigerate after reconstitution (2–8°C):

Once dissolved in bacteriostatic water, sterile PBS, or cell culture media, store at 2-8°C (standard laboratory refrigerator). Use within 14 days for bacteriostatic water formulations or 21 days if preservative-containing vehicles are used. Do NOT freeze reconstituted solutions as ice crystals can disrupt the copper-peptide complex.

Important note on solution color: Reconstituted GHK-Cu solutions should appear blue to blue-violet. The intensity of the blue color correlates with copper concentration. Colorless or green solutions indicate copper dissociation or contamination – do not use.

3. Avoid repeated freeze-thaw cycles:

The copper complex is susceptible to disruption upon freeze-thaw. Aliquot reconstituted peptide into single-use portions (e.g., 50-100 µL in sterile PCR tubes) before freezing if long-term storage after reconstitution is necessary. Each aliquot should undergo no more than ONE freeze-thaw cycle.

4. Protect from light and moisture:

Store original lyophilized vials in the provided amber container or foil-wrapped box. GHK-Cu is photosensitive – prolonged light exposure causes copper photoreduction and peptide degradation. Use amber glass vials for working solutions.

5. Maintain sterile conditions:

Always use a sterile syringe, 0.22 µm filter, and laminar flow hood when piercing the septum. Contamination leads to endotoxin buildup (>10 EU/mg) which activates TLR4 pathways and confounds fibroblast signaling studies.

6. Desiccate lyophilized powder:

Store unopened vials with the provided desiccant pack. Open vials only in low-humidity environments (<30% RH) to prevent moisture absorption, which causes peptide aggregation and copper displacement.

Stability timeline:

• Lyophilized at -20°C: 24 months (≥98% purity)

• Lyophilized at 2-8°C: 6 months (≥95% purity)

• Lyophilized at room temperature: 14 days (≥90% purity)

• Reconstituted at 2-8°C: 14-21 days (≥90% purity, blue color should persist)

• Reconstituted at room temperature: 24-48 hours

For fibroblast culture studies: Prepare fresh working solutions from lyophilized aliquots every 7-10 days for optimal biological activity. Discard any solution that loses its blue color.

Failure to follow these guidelines may result in copper dissociation (colorless solution) or peptide degradation, skewing your ECM and wound healing data.

🧪 How It Is Used

Reconstitution Protocol for In Vitro Studies

1. Centrifuge the sealed vial:

• Centrifuge at 3,000 RPM for 2 minutes to pull lyophilized blue powder to the bottom. This prevents loss when opening.

2. Prepare sterile vehicle:

• For cell culture (fibroblast studies): Use sterile, endotoxin-free PBS or serum-free DMEM.

• For ex-vivo wound healing research: Reconstitute in bacteriostatic water then dilute in hydrogel or cream base.

• For stock solutions: Use sterile water (10-20 mg/mL) – solution should appear deep blue.

3. Add vehicle to achieve desired stock concentration:

• Standard stock for cell culture: 10 mg/mL (add 20 mL vehicle to 200mg vial)

• Working solution: Dilute stock 1:100 to 1:1000 in culture media (final 10-100 µg/mL or 25-250 µM)

4. Swirl gently:
Do NOT vortex or shake vigorously as this causes foaming and may disrupt the copper complex.

5. Allow 3-5 minutes for complete dissolution:
Solution should be clear blue to blue-violet. Colorless or green solution indicates copper dissociation – do not use.

How is GHK-Cu stored for long-term stability?

Long-term storage (lyophilized powder): Store at -20°C (±5°C) in a non-frost-free laboratory freezer. Do NOT use a self-defrosting (auto-defrost) freezer as temperature fluctuations cause peptide aggregation. Unopened vials are stable for 24 months. The lyophilized powder should appear blue to blue-violet.

After reconstitution: Store at 2-8°C (refrigerate). Use within 14 days if reconstituted in bacteriostatic water or sterile PBS. Use within 21 days if reconstituted with preservative-containing vehicles. Do NOT freeze reconstituted solutions – ice crystals can disrupt the copper-peptide complex.

Important visual check: Reconstituted GHK-Cu should be blue to blue-violet. Colorless or green solutions indicate copper dissociation – discard and do not use.

Handling tips: Allow frozen vials to come to room temperature (15 minutes) before opening. Aliquot reconstituted solutions for single-use portions to avoid repeated freeze-thaw cycles.

How is GHK-Cu used in research?

Reconstitution protocol:

1. Centrifuge sealed vial at 3,000 RPM for 2 minutes (blue powder at bottom)

2. Under laminar flow hood, sterilize septum with 70% isopropyl alcohol

3. Add 20 mL sterile PBS or bacteriostatic water for 10 mg/mL stock

4. Swirl gently – do NOT vortex

5. Allow 3-5 minutes for complete dissolution (blue solution)

In vitro applications (fibroblast culture):

• Cell types: Primary human dermal fibroblasts (HDFa), HFF-1

• Concentration: 0.1-100 µM (optimal 1-10 µM for collagen studies)

• Treatment duration: 24-72 hours for gene expression; 7-21 days for collagen accumulation

• Positive control: TGF-β1 (1-10 ng/mL) for collagen synthesis comparison

• Negative control: GHK without copper (apo-GHK) to assess copper dependence

Ex-vivo wound healing:

• Skin explants with full-thickness excisional wounds

• Concentration: 1-50 µM topical application

• Duration: 3-14 days

• Readouts: Wound closure rate (planimetry), re-epithelialization

Strictly for research purposes only.

Can GHK-Cu be stacked with other peptides?

Yes. Common research combinations include:

• GHK-Cu + BPC-157: Angiogenesis + matrix deposition + cross-linking studies

• GHK-Cu + Thymosin Beta-4 (TB-500): Inflammation reduction + ECM synthesis

• GHK-Cu + Rigin (Palmitoyl Tetrapeptide-7): Anabolic + anti-catabolic matrix studies

• GHK-Cu + AHK (Tripeptide-3): Collagen synthesis + cross-linking synergy

• GHK-Cu + Matrixyl (Palmitoyl Pentapeptide-4): Comparative matrikine studies

• GHK-Cu + CuCl₂ (copper control): Copper delivery mechanism studies

• GHK-Cu + GHK (without copper): Copper-dependent mechanism studies

Typical ratio: 1:1 to 2:1 (GHK-Cu:partner). Bulk stacking discounts available (15% off for 3+ peptides, 25% off for 5+ peptides).
