About the GHK-Cu Reconstitution Calculator
GHK-Cu (copper tripeptide-1) is typically supplied as a 50 mg or 100 mg lyophilized vial and reconstituted with bacteriostatic water for research use. Because doses are commonly in the 1–3 mg range, you want a concentration that lets a dose draw as a manageable number of insulin units.
Enter your vial strength, water volume, and dose. The calculator returns the mg/mL concentration, the mL to draw, and the U-100 insulin units. A 50 mg vial reconstituted with 5 mL of bacteriostatic water yields 10 mg/mL, making a 1 mg dose exactly 0.1 mL (10 units).

How to prepare GHK-Cu
- Draw the intended volume of bacteriostatic water into a sterile syringe.
- Slowly inject the water down the inside wall of the GHK-Cu vial — never directly onto the lyophilized powder.
- Gently swirl (do not shake) until the powder is fully dissolved and the solution is clear.
- Store the reconstituted vial refrigerated at 2–8°C and use within the peptide's stability window.
- Use the concentration and dose volume calculated above to draw each research dose into an insulin syringe.
Frequently asked questions
How do I reconstitute GHK-Cu?
Add bacteriostatic water to the GHK-Cu vial using the volume the calculator recommends for your desired concentration. Slowly inject the water down the side of the vial, swirl gently, and store the vial refrigerated.
What bacteriostatic water volume should I use for GHK-Cu?
Common choices are 1 mL, 2 mL, or 3 mL of bacteriostatic water. The right volume depends on your vial strength and target dose — use the calculator above to get a concentration that lets you draw your dose in whole insulin units.
What is a typical research dose range for GHK-Cu?
Reported research dose ranges for GHK-Cu are 1–3 mg per research dose. Always verify against current literature — this tool is for research reference only, not medical advice.
How long is GHK-Cu stable after reconstitution?
Once reconstituted with bacteriostatic water and stored refrigerated (2–8°C), most peptides remain stable for roughly 28–30 days. Check the specific stability data for GHK-Cu for your batch.
Can I use this GHK-Cu calculator with any insulin syringe?
Yes. The calculator supports U-100 syringes in 30, 50, and 100-unit capacities and shows both the mL dose volume and the equivalent insulin units for whichever syringe you choose.
