Key features:

• Naturally occurring copper peptide complex found in human plasma, saliva, and urin
• Lyophilised for stability, easy reconstitution
• Suitable for subcutaneous administration in approved research protocols
• Stored refrigerated at 2–8°C after delivery

Suggested reconstitution (research use only)

Reconstitute 50 mg with 5 mL bacteriostatic water to yield 10,000 mcg/mL. Insulin syringe reference (U-100):

•1 IU = 100 mcg
•500 mcg = 5 IU (0.05 mL)
•1,000 mcg = 10 IU (0.1 mL)
•2,000 mcg = 20 IU (0.2 mL)

Typical research scheduling:

Daily or twice-daily subcutaneous administration is commonly studied. Many protocols explore 1,000–2,000 mcg daily for 4–8 weeks. Some researchers also explore topical application in relevant study contexts. Geno X does not recommend or prescribe dosing.

Storage and handling

Keep refrigerated at 2–8°C. Protect from light. Do not freeze. Vials are shipped appropriately and are stable for transit; refrigerate on arrival.

Compliance note

Research compound. Not for human consumption, therapeutic use, or diagnostic procedures. Not TGA-approved.

FAQ

How is it supplied? Lyophilised powder in a 50 mg vial.

Is this for human use? No. Research use only. Not a therapeutic good. No medical advice is provided.

How is it handled in a lab setting? Reconstitute with bacteriostatic water to your required concentration. Store at 2–8°C, protect from light, do not freeze. Follow your institution’s protocols.

What schedule is commonly studied? Many protocols explore daily or twice-daily subcutaneous administration. Some researchers investigate topical delivery methods in relevant study contexts. Geno X does not recommend or prescribe dosing.

What is GHK-Cu? A naturally occurring copper-binding tripeptide (Glycyl-L-Histidyl-L-Lysine) found in human plasma, studied for effects on wound healing, collagen synthesis, antioxidant activity, skin remodelling, and anti-inflammatory markers (investigational).

Any known tolerability profile in studies? GHK-Cu is generally well-tolerated in preclinical and early research settings. Observations include mild injection-site reactions in some subjects. Topical application studies report minimal adverse effects. Provided for research context only.
