GHK-Cu (Copper) (50mg) Research Peptide: A Bioactive Copper Tripeptide for Fibroblast, ECM & Tissue Repair Studies

If your research investigates extracellular matrix (ECM) biology, fibroblast signalling, wound healing, or the molecular mechanisms of tissue repair and regeneration, GHK‑Cu (Copper) (50mg) research peptide offers a naturally occurring and extensively studied synthetic tool. GHK-Cu (glycyl‑L‑histidyl‑L‑lysine‑copper complex), also known as copper tripeptide‑1, is a naturally occurring tripeptide first identified and developed by Loren Pickart in 1973. Found naturally in human plasma, saliva, and urine, this small molecule possesses a strong affinity for binding to copper(II) ions.

Discovered over 50 years ago, GHK-Cu acts as both a signal and a carrier peptide, supporting extracellular matrix remodelling and being released at sites of inflammation or tissue injury, where it promotes collagen, elastin, proteoglycan, and glycosaminoglycan synthesis while exerting potent anti‑inflammatory and antioxidant effects. This makes GHK-Cu (Copper) (50mg) research peptide a valuable tool for laboratories investigating fibroblast biology, collagen synthesis, ECM dynamics, wound healing, and the molecular biology of tissue regeneration.

At Wuhan Top Miracle Peptides, we supply high‑purity GHK‑Cu (Copper) (50mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into fibroblast biology, ECM dynamics, and tissue regeneration begin with uncompromising quality.

What Is GHK‑Cu and How Does It Work?

To fully appreciate the research potential of GHK‑Cu (Copper) (50mg) research peptide, it is essential to understand its biochemical identity, its role as an endogenous copper‑binding tripeptide, and the mechanisms by which it exerts its pleiotropic effects.

The Copper‑Binding Tripeptide

GHK‑Cu is a naturally occurring copper‑binding tripeptide with the amino acid sequence Gly‑His‑Lys, complexed with a copper(II) ion. Its molecular formula is C₁₆H₂₆CuN₆O₆ (for the acetate salt), with a molecular weight of approximately 461.96 g/mol. It has a CAS number of 89030‑95‑5. The peptide is the basic form in which copper is transported in tissues and permeates through cell membranes.

The molecule has a strong affinity for copper(II) ions, forming the chelated complex GHK‑Cu. Physiologically, plasma concentrations of GHK average about 200 ng/mL at age 20 but decline to approximately 80 ng/mL by age 60, a reduction that may reflect the body’s decreased regenerative capacity over time.

Mechanism of Action: Matrikine Signalling, Gene Modulation & Copper Transport for GHK-Cu (Copper) (50mg)

The biological activity of GHK‑Cu (Copper) (50mg) research peptide is mediated through several intersecting mechanisms:

• Matrikine Signalling and Gene Modulation: GHK-Cu’s primary mechanism of action is its profound influence on gene expression. Research has shown that GHK can modulate the activity of thousands of human genes, essentially resetting them to a younger, healthier state. It acts as a signal peptide, communicating with cells to promote repair and regeneration.

• Copper Transport and Carrier Function: GHK‑Cu serves as a carrier peptide, stabilising and transporting copper ions critical for wound healing, enzymatic activation, and tissue regeneration. It facilitates the delivery of copper to cells, where it is required for collagen and elastin formation.

• Fibroblast Activation and ECM Synthesis: GHK‑Cu stimulates fibroblast proliferation, collagen synthesis, angiogenesis, and ECM remodelling. It increases messenger RNA production for collagen, elastin, proteoglycans, and glycosaminoglycans in fibroblasts. It stimulates collagen synthesis in fibroblasts and increases the proliferative potential of keratinocytes by regulating extracellular matrix proteins such as α6 and β1 integrins.

• Anti‑Inflammatory and Antioxidant Effects: GHK‑Cu possesses potent anti‑inflammatory and antioxidant effects. Studies have shown that GHK‑Cu notably decreases the migration of neutrophils and macrophages, suppresses the expression of pro‑inflammatory cytokines (tnf‑a, il‑1β, il6) and increases the expression of the anti‑inflammatory cytokine il‑10. It also mitigates oxidative stress by reducing levels of nitric oxide (NO) and reactive oxygen species (ROS), and improves superoxide dismutase (SOD) activity. GHK‑Cu reduces ROS production, increases SOD activity, and decreases TNF‑α and IL‑6 production through the suppression of NF‑κB p65 and p38 MAPK signalling. It may exert its anti‑inflammatory effects via the JAK/STAT signalling pathway.

• Angiogenesis and Growth Factor Stimulation: GHK‑Cu promotes angiogenesis by increasing the expression of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF).

• Oxidative Stress Mitigation: GHK‑Cu reduces ROS and NO levels and improves SOD activity.

• NF‑κB and MAPK Signalling: GHK‑Cu suppresses NF‑κB p65 and p38 MAPK signalling.

• JAK/STAT Pathway: GHK‑Cu may exert its effects via the JAK/STAT signalling pathway.

4. Skin Rejuvenation and Anti‑Ageing Research

GHK‑Cu has been studied for its effects on skin biology and ageing:

• Skin Tightening and Elasticity: Controlled studies on aged skin demonstrated that GHK‑Cu tightens skin, improves elasticity and firmness, reduces fine lines, wrinkles, photodamage and hyperpigmentation.

• Hair Growth: GHK‑Cu is a powerful hair growth promoter with minimal side effects when compared with minoxidil and finasteride.

5. Gene Expression and Epigenetic Research

GHK‑Cu’s ability to modulate gene expression positions it as a valuable tool for studying transcriptional regulation:

• Gene Modulation: GHK can modulate the activity of thousands of human genes.

• SIRT1 Activation: GHK‑Cu decreases TGF‑β1 levels by increasing SIRT1 expression and activating SIRT1 deacetylation.

Chemical & Physical Specifications for GHK-Cu (Copper) (50mg)

Accurate characterisation of GHK‑Cu (Copper) (50mg) research peptide is essential for reproducible experimental design.

Note: The 50 mg mass refers to the weight of the peptide in its lyophilised form. GHK‑Cu is typically supplied as an acetate salt, which enhances aqueous solubility. The peptide is distinct from the unbound GHK tripeptide.

Reconstitution & Handling Protocol for GHK‑Cu (Copper) (50mg)

Proper reconstitution of GHK‑Cu (Copper) (50mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed GHK‑Cu vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the GHK‑Cu vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 50 mg per 5 mL of diluent, yielding a 10 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted GHK‑Cu into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.

• Once thawed, store at 0‑4°C and use within 1 month.

Concentration Reference Table for GHK-Cu (Copper) (50mg)
