Description

GHK-Cu Peptide – High-Purity Copper Peptide Research Compound

Product Overview

GHK-Cu peptide is a synthetic copper-binding tripeptide complex composed of glycyl-L-histidyl-L-lysine bound to a copper ion. In scientific literature, GHK-Cu has been investigated in studies involving cell signaling, extracellular matrix remodeling, collagen-related pathways, wound-healing research, skin biology, hair-follicle research, and peptide-mediated regenerative signaling.

This product is supplied as a blue lyophilized powder intended strictly for laboratory and scientific research purposes only. Each batch is manufactured under controlled conditions and tested for identity and purity to support reliable research applications.

Purity and Quality Assurance

Each batch of GHK-Cu peptide undergoes analytical testing to verify:

• HPLC purity ≥98%
• Peptide identity by mass spectrometry
• Copper-complex verification
• Visual inspection for color and consistency
• Controlled lyophilization and moisture-reduction procedures

These quality-control measures help ensure consistent performance and reliable batch-to-batch reproducibility for research environments.

Appearance

• Color: Blue to blue-violet
• Form: Sterile-filtered lyophilized powder
• Odor: Odorless
• Solubility: Soluble in appropriate aqueous research solvents after reconstitution

The characteristic blue coloration is a normal property of the copper-peptide complex and is commonly used as a visual indicator of proper copper binding.

Storage Recommendations

Before Reconstitution

• Store at -20°C for long-term preservation
• Protect from light, heat, and moisture
• Keep the vial tightly sealed until use
• Avoid unnecessary temperature fluctuations

After Reconstitution

• Store refrigerated at 2-8°C
• Protect from prolonged light exposure
• Avoid repeated freeze-thaw cycles
• Follow your laboratory’s validated stability and handling procedures

Because copper-peptide complexes may be sensitive to oxidation under certain conditions, proper cold-chain handling is recommended.

General Reconstitution Information

For laboratory preparation:

1. Allow the vial to equilibrate to room temperature before opening.
2. Add an appropriate sterile research-grade diluent slowly along the inside wall of the vial.
3. Gently swirl until the powder is completely dissolved.
4. Do not shake vigorously or vortex aggressively, as excessive agitation may contribute to foaming and may affect peptide stability.

The choice of diluent and final concentration should be determined according to the researcher’s validated protocol and analytical requirements.

Frequently Asked Questions (FAQ)

What is GHK-Cu peptide?

GHK-Cu peptide is a synthetic copper-binding tripeptide complex consisting of glycyl-L-histidyl-L-lysine bound to a copper ion. It has been studied in experimental research involving cell signaling, extracellular matrix remodeling, collagen-related pathways, and skin and hair biology research.

Why is GHK-Cu blue?

The blue color is caused by the copper ion bound to the GHK peptide. This coloration is a normal characteristic of the copper-peptide complex and does not indicate contamination.

What does ≥98% by HPLC mean?

This means that at least 98% of the analyzed material corresponds to the target copper-peptide compound when tested using High-Performance Liquid Chromatography (HPLC), a standard analytical method used to assess peptide purity.

Why is GHK-Cu supplied as a lyophilized powder?

Lyophilization removes water from the peptide preparation, helping improve stability during storage and transportation and reducing degradation prior to reconstitution.

How should unopened vials be stored?

Unopened vials should be stored at -20°C, protected from light and moisture, for optimal long-term stability.

Can the peptide be refrigerated after reconstitution?

Yes. After reconstitution, it should generally be stored at 2-8°C and protected from excessive light exposure. Laboratories should follow their own validated stability and handling procedures.

What diluent should be used?

The appropriate sterile research-grade diluent depends on the specific experimental protocol. Researchers should select solvents and concentrations according to their validated laboratory methods.

Is this product sterile?

The peptide is produced using controlled manufacturing processes and sterile filtration prior to lyophilization; however, it is sold for research use only, and researchers are responsible for following appropriate sterility and handling procedures.

Is GHK-Cu peptide suitable for human use?

No. GHK-Cu peptide sold on this website is strictly for research purposes only and is not intended for human or veterinary use.

Do you provide lot or batch identification?

Yes. Each vial includes a lot number for inventory control, traceability, and laboratory record-keeping purposes.
