GHK-Cu calculator
Enter your GHK-Cu vial size, added water, and dose to view the units needed on a U-100 insulin syringe.
Just for reference. The dose is set by your prescriber or the product label; here we only convert it to units.
- sizes of vials sold
- 50 mg, 100 mg
- status of approval
- It is not FDA-approved
- example mix: 50 mg with 5 mL
- 10 mg in each mL
The math behind GHK-Cu
To find the strength, divide what's in the vial by the water. If you add 5 mL of water to a 50 mg vial, each mL holds 10 mg. First divide your dose by that strength for mL; then multiply that number by 100 to get units on a U-100 syringe.
From that vial, 200 mcg comes to 0.02 mL, and that equals 2 units.
GHK-Cu unit values at a glance
| Your dose | 50 mg vial + 5 mL |
|---|---|
| 200 mcg | 2 units |
| 250 mcg | 2.5 units |
| 400 mcg | 4 units |
| 750 mcg | 7.5 units |
| 1 mg | 10 units |
| 2 mg | 20 units |
| 3 mg | 30 units |
| 4 mg | 40 units |
| 7.5 mg | 75 units |
Based on the specified vial and water, each cell marks the U-100 syringe line to draw to.
Is GHK-Cu FDA-approved?
It isn't FDA-approved for any use in people; it's sold as a research chemical. There's no FDA label for it, so no official dose exists. All we do is convert the dose you already have.
Questions people often ask
How much water goes into a 50 mg GHK-Cu vial?
You choose how much water to add; it only changes the strength of each mL. Using 5 mL gives 10 mg in every mL; with extra water each unit holds less, and small doses become easier to measure.
How many units equal 1 mg of GHK-Cu?
That depends on how strong your mix is. At 10 mg/mL, 1 mg equals 10 units. Type your own vial and water into the calculator and your number appears.
How long is mixed GHK-Cu good for?
Your product or prescription gives the storage line; follow it. CDC guidance says you should use bacteriostatic water itself within 28 days, counting from the first needle.
