GHK-CU — Research Protocol

Quickstart Highlights

Reconstitution Summary
GHK-Cu (Copper Tripeptide-1) is supplied as a sterile, lyophilized peptide intended for laboratory research. It is commonly reconstituted with bacteriostatic water prior to experimental use.

Typical Research Concentration
The final concentration depends on the amount of bacteriostatic water added during reconstitution.

Easy Measuring Note
After reconstitution, calculate the concentration based on the total volume of diluent used. Verify calculations before preparing research solutions.

Storage

• Store unreconstituted vials in a cool, dry place protected from light.
• Refrigerate after reconstitution (2–8°C / 36–46°F).
• Protect from direct light, as copper-peptide complexes are light-sensitive.
• Avoid repeated freeze-thaw cycles.
• Do not use if the solution becomes cloudy, discolored, or contains visible particles.

Dosing & Reconstitution Guide

Reconstitute: Prepare the 50 mg vial to a final volume of 3.0 mL for a concentration of 16.67 mg/mL.

Phase	Dose (per injection)	Units (per injection)
Weeks 1-4	1.0 mg	6 units
Weeks 5-8	1.5 mg	9 units
Weeks 9-12+	2.0 mg	12 units

 

Frequency: Once daily, 5 days per week, progressing from 1.0 mg to 1.5 mg and then 2.0 mg as shown above. At 16.67 mg/mL, those doses equal 6, 9, and 12 U-100 units. Use a U-100 syringe with markings that clearly display every value in the table.

Reconstitute: Prepare the 100 mg vial to a final volume of 3.0 mL for a concentration of 33.33 mg/mL.

Phase	Dose (per injection)	Units (per injection)
Weeks 1-4	1.0 mg	3 units
Weeks 5-8	1.5 mg	4.5 units
Weeks 9-12+	2.0 mg	6 units

 

Frequency: Once daily, 5 days per week, progressing from 1.0 mg to 1.5 mg and then 2.0 mg as shown above. At 33.33 mg/mL, those doses equal 3, 4.5, and 6 U-100 units. Use a U-100 syringe with markings that clearly display every value in the table.

Protocol Overview

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding tripeptide consisting of glycine, histidine, and lysine complexed with copper (Cu²⁺). It is supplied as a lyophilized powder and is reconstituted with a sterile diluent prior to laboratory use.

Researchers should follow aseptic handling procedures, accurately calculate solution concentrations, protect the peptide from prolonged light exposure, and properly store reconstituted material to maintain stability throughout the research period.

How It Works

GHK-Cu is an endogenous peptide naturally found in human plasma, saliva, and urine. Natural concentrations decline with age, making it a significant area of regenerative biology research.

Preclinical studies suggest GHK-Cu may influence numerous biological pathways involved in:

• Collagen and elastin synthesis
• Extracellular matrix remodeling
• Fibroblast activity
• Wound healing mechanisms
• Angiogenesis (formation of new blood vessels)
• Antioxidant defense
• Inflammatory signaling
• Hair follicle biology
• Gene expression associated with tissue repair

Although GHK-Cu has demonstrated promising biological activity in laboratory and preclinical studies, it has not been approved by the U.S. Food and Drug Administration for the diagnosis, treatment, cure, or prevention of any disease.

Potential Benefits & Side Effects

Published research has explored GHK-Cu in relation to:

• Skin regeneration
• Collagen production
• Wound healing
• Hair follicle biology
• Connective tissue remodeling
• Anti-inflammatory pathways
• Antioxidant mechanisms
• Scar remodeling
• Healthy aging research

These represent areas of scientific investigation and should not be interpreted as established therapeutic uses.

Safety Information

GHK-Cu is not FDA approved as a therapeutic drug in the United States. Human safety data for injectable use remain limited, and long-term safety has not been established.

Potential research considerations include:

• Unknown long-term safety profile
• Product contamination if aseptic technique is not followed
• Local irritation associated with research administration procedures
• Light sensitivity of copper-peptide complexes
• Risks associated with improper preparation or handling

Researchers should follow established laboratory safety procedures and comply with all applicable institutional and regulatory requirements.
