⚠️ Disclaimer

GHK-Cu is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.

GHK-Cu is typically reconstituted with bacteriostatic water (BAC water). The standard dosage of 1-3 mg (injectable), topical formulations vary is administered once daily via subcutaneous injection or topical application. Use our peptide calculator for exact mixing ratios.

How Do You Reconstitute GHK-Cu?

GHK-Cu is supplied as a lyophilized (freeze-dried) powder that must be reconstituted before use. Proper reconstitution is critical for accurate dosing and maintaining stability.

This guide covers the step-by-step process for mixing GHK-Cu with bacteriostatic water to achieve your target concentration.

What Supplies Do You Need?

To reconstitute GHK-Cu, you need: the GHK-Cu vial (lyophilized powder), bacteriostatic water (BAC water with 0.9% benzyl alcohol), insulin syringes (typically 1mL/100-unit), alcohol swabs, and a clean workspace.

Important: Always use bacteriostatic water — not sterile water or saline. BAC water's benzyl alcohol prevents bacterial contamination, extending the usable life of reconstituted GHK-Cu to 4-6 weeks.

Step-by-Step GHK-Cu Reconstitution

Step 1: Clean the vial tops of both the GHK-Cu and BAC water with alcohol swabs.

Step 2: Draw the calculated amount of BAC water into an insulin syringe. Use our peptide calculator to determine the exact amount.

Step 3: Insert the needle into the GHK-Cu vial at an angle, and let the water run down the side of the glass — never spray directly onto the powder as this can damage the peptide bonds.

Step 4: Gently swirl (do not shake) the vial until the powder is fully dissolved. The solution should be clear.

Step 5: Label the vial with the date and concentration. Store at 2-8°C.

How Do You Dose Reconstituted GHK-Cu?

After reconstitution, the standard GHK-Cu dose is 1-3 mg (injectable), topical formulations vary administered once daily via subcutaneous injection or topical application. The number of units on your insulin syringe depends on how much BAC water you added.

Our calculator will tell you exactly how many units to draw for your dose based on your specific reconstitution ratio.

How Do You Store Reconstituted GHK-Cu?

Store reconstituted GHK-Cu at 2-8°C (standard refrigerator temperature). Use within 4-6 weeks. Keep away from light and temperature fluctuations.

Unreconstituted GHK-Cu powder can be stored at -20°C for 12+ months. Once you reconstitute it, the clock starts.

Bottom Line

Reconstituting GHK-Cu is straightforward — add BAC water, swirl gently, refrigerate. The key is using the right amount of water for accurate dosing. Use our peptide calculator every time.

Frequently Asked Questions

What is GHK-Cu?

GHK-Cu (GHK-Cu (Copper Peptide)) is a Tripeptide-copper complex. Naturally occurring peptide found in human plasma, saliva, and urine; levels decline significantly with age from 200 ng/mL at age 20 to 80 ng/mL by age 60. It is researched for skin rejuvenation, wound healing, anti-aging, hair growth, collagen production, anti-inflammatory effects.

What is the recommended GHK-Cu dosage?

Common dosages: 1-3 mg (injectable), topical formulations vary administered once daily via subcutaneous injection or topical application. Cycle length: 4-12 weeks. Half-life: approximately 2-4 hours. Use our peptide calculator for exact reconstitution math.

What are the side effects of GHK-Cu?

Well-tolerated in research and cosmetic use. Mild injection site reactions possible. Topical use may cause temporary skin redness in sensitive individuals. No systemic toxicity reported.

Is GHK-Cu safe?

GHK-Cu has shown a favorable safety profile in research. Not regulated as a drug. Available as a research chemical and widely used in cosmetic formulations. One of the most accessible peptides legally. All research should follow appropriate safety protocols.
