What is GHK-Cu?
GHK-Cu is a naturally occurring copper peptide made from the tripeptide glycyl-L-histidyl-L-lysine bound with copper. It is most commonly discussed in research for its links with wound healing, tissue remodelling, collagen support, skin regeneration and anti-inflammatory pathways.
In research discussions, GHK-Cu is often associated with skin health, connective tissue repair, collagen synthesis, antioxidant defence, wound healing pathways and broader gene-regulation effects.
GHK-Cu Reconstitution Example
The example below is based on a common 50mg GHK-Cu vial mixed with 3.0mL bacteriostatic water.
Reconstitution Maths
50mg ÷ 3.0mL = 16.67mg/mL
16.67mg/mL = 16,670mcg/mL
1 unit on a U-100 syringe = 0.01mL
16,670mcg/mL × 0.01mL = approximately 167mcg per unit
Standard Research Protocol Example
This example uses a 50mg vial reconstituted with 3.0mL bacteriostatic water, giving a concentration of 16.67mg/mL.
Alternative 3 Times Per Week Example
Another research-style schedule commonly discussed is 2.0mg per administration, 3 times per week, using the same 50mg vial mixed with 3.0mL bacteriostatic water.
Frequency and Timing Notes
GHK-Cu is commonly discussed as a subcutaneous compound in research-style protocols. Two common schedules are 5 days per week with gradual titration, or 3 times per week at a consistent amount.
Timing is usually less specific than peptides linked with sleep or circadian rhythm. The main practical point is consistency, using the same general time of day and rotating injection sites.
Reconstitution Steps
- Confirm the vial size before calculating concentration.
- Draw 3.0mL bacteriostatic water using sterile technique.
- Inject the bacteriostatic water slowly down the inside wall of the vial.
- Avoid blasting the powder directly and avoid creating foam.
- Gently swirl or roll the vial until the powder is fully dissolved.
- Do not shake aggressively.
- Label the vial with the reconstitution date.
- Store the reconstituted vial in the refrigerator at 2-8°C, protected from light.

How GHK-Cu Works
GHK-Cu complexes with copper ions and is discussed for its role in multiple tissue repair and regeneration pathways. Research commonly focuses on its relationship with collagen expression, wound healing, tissue remodelling and antioxidant defence.
It is also discussed for gene-regulatory activity, including pathways linked with inflammation, growth factors, antioxidant enzymes and connective tissue repair. This is one reason GHK-Cu appears frequently in skin health, wound healing and regenerative research.
While GHK-Cu is naturally occurring and widely discussed, it should still be treated as a research compound in this context. There are no official broad human dosing guidelines for general use.
Potential Benefits Discussed in Research
- Wound healing research
- Skin regeneration pathways
- Collagen synthesis and remodelling
- Connective tissue support research
- Antioxidant defence pathways
- Anti-inflammatory signalling research
- Growth factor regulation discussions
- Nervous system and cognitive pathway research
- General tissue repair and regeneration discussions
Reported Side Effects and Limitations
GHK-Cu is often described as well tolerated in research and clinical-practice discussions, but side effects and individual responses can still vary.
- Mild injection-site redness
- Temporary itching or irritation
- Local swelling or sensitivity
- Possible discomfort if injected too quickly
- Unknown long-term outcomes outside studied settings
- No official universal dosing guidelines for general human use
Storage Instructions
- Lyophilised powder: store frozen at around -20°C for longer-term storage, protected from heat, moisture and light.
- After reconstitution: refrigerate at 2-8°C.
- Use window: commonly discussed as within 30 days after reconstitution.
- Avoid: heat, sunlight, contamination and repeated freeze-thaw cycles.
- Aliquoting note: for longer storage, some research handling guidance discusses dividing solution into sterile vials to avoid repeated thawing.
- Practical note: allow cold vials to reach room temperature before opening to reduce condensation exposure.
Injection Technique Notes
This section is general educational information only. It is not personal injection instruction.
- Use a new sterile insulin syringe for each administration.
- Clean the vial stopper and skin with alcohol and allow both to dry.
- Common subcutaneous sites discussed include abdomen, thighs and upper arms.
- Rotate injection sites to reduce irritation and local tissue issues.
- Pinch a skinfold and insert into subcutaneous tissue at an appropriate angle.
- Do not aspirate for subcutaneous injections.
- Inject slowly and steadily.
- Withdraw the needle at the same angle used for insertion.
- Do not rub the site afterwards.
- Dispose of used sharps safely in a sharps container.
Lifestyle Factors That May Matter
- Protein intake: adequate protein supports normal tissue repair and collagen processes.
- Micronutrients: vitamin C, zinc and copper status are commonly discussed in connective tissue health.
- Hydration: supports general tissue and skin health.
- Sleep quality: recovery and repair processes are closely linked with sleep.
- Stress management: chronic stress may interfere with recovery and inflammation balance.
- Skincare and wound-care context: topical routines or wound-care plans may be relevant depending on the research goal.
- Tracking: documenting amount, date and site rotation can make observations easier to review.
