GHK-Cu is a naturally occurring copper peptide studied for its roles in tissue remodeling, antioxidant defense, and skin repair. This protocol outlines its use with a 50 mg vial, reconstituted to a specific concentration for subcutaneous administration, with varying dosage regimens for research purposes.
- 50 mg vial reconstituted with 3.0 mL for a 16.67 mg/mL concentration.
- Dosages range from 1.0 mg to 2.0 mg per injection.
- Administered subcutaneously 3 to 5 days per week.
- 1.0 mg equals 6 units, 1.5 mg equals 9 units, and 2.0 mg equals 12 units on a U-100 syringe.

How it works
GHK-Cu is a naturally occurring peptide that binds copper and plays a role in extracellular matrix signaling and remodeling. It has been researched for its involvement in collagen-related pathways, antioxidant defense, and tissue repair. Studies have explored its effects in human topical applications for skin and wound care, and an animal model provided insight into local administration. The observed effects are linked to the specific route, formulation, concentration, and design of each study, with current research highlighting its potential in regenerative processes.
Reported effects
- Supports research on collagen-related signaling and tissue repair.
- Examined in human topical and wound-care studies for skin outcomes.
- Linked to extracellular matrix remodeling and antioxidant defense.
Reported side effects
Storage
Lyophilised (unmixed)
Store according to vial and batch documentation, protecting from moisture, light, and temperature extremes.
After reconstitution
Stability is dependent on concentration, pH, diluent, sterility, container, preservatives, and temperature. Minimize light and moisture exposure. Record preparation date, concentration, and disposal date.
Supplies
| Peptide vials | 1-3 vials of 50 mg GHK-Cu, depending on protocol length (8-16 weeks). |
|---|---|
| Insulin Syringes (U-100, 29-31 gauge) | 24-80 syringes, depending on protocol length and frequency. |
| Sterile or Bacteriostatic Water (10 mL bottles) | 3-9 mL needed, depending on the number of vials. |
| Alcohol Swabs | 48-160 swabs for preparing vial stoppers and injection sites. |
Important notes
- Always use sterile equipment for each preparation and administration.
- Follow aseptic technique, ensuring the skin antiseptic dries before injection.
- Rotate injection sites systematically and dispose of sharps safely.
- Document the date, amount, preparation identifier, and injection site for consistent research.
Frequently asked questions
What is the recommended reconstitution for a 50 mg GHK-Cu vial?
For a 50 mg GHK-Cu vial, it is recommended to reconstitute with 3.0 mL of sterile or bacteriostatic water, resulting in a concentration of 16.67 mg/mL.
How do I measure the correct dose of GHK-Cu using a U-100 syringe?
When reconstituted to 16.67 mg/mL, 1.0 mg of GHK-Cu equals 6 units, 1.5 mg equals 9 units, and 2.0 mg equals 12 units on a U-100 insulin syringe.
Can I use GHK-Cu every day?
The standard protocol suggests administration 5 days per week, with an alternative protocol using it 3 times per week. Daily use without breaks is not specified in the protocol.
What are the key differences between the standard and alternative dosing protocols?
The standard protocol for GHK-Cu involves increasing doses from 1.0 mg to 2.0 mg over 12+ weeks, administered 5 days per week. The alternative protocol maintains a consistent dose of 2.0 mg, administered 3 times per week over the same period.
