GHK-Cu Calculator
Enter your GHK-Cu vial size, the water you add and your dose to get the units to draw on a U-100 syringe. The units chart and water table below cover 50, 100 mg vials.
How many units is each GHK-Cu dose?
Units on a U-100 insulin syringe for common amounts, with 3 mL of bacteriostatic water in the vial. With a different water amount, use the calculator above.
| Dose (mg) | 50 mg vial + 3 mL | 100 mg vial + 3 mL |
|---|---|---|
| 0.5 mg | 3 units 0.03 mL | 1.5 units 0.015 mL |
| 1 mg | 6 units 0.06 mL | 3 units 0.03 mL |
| 2 mg | 12 units 0.12 mL | 6 units 0.06 mL |
| 3 mg | 18 units 0.18 mL | 9 units 0.09 mL |
How much bac water for GHK-Cu?
Water only changes how much liquid each dose takes up, not how much GHK-Cu is in it. To land a 1 mg dose on a round number of units, add:
| Vial | So 1 mg = 10 units | So 1 mg = 20 units |
|---|---|---|
| 50 mg | 5 mL | 10 mL |
| 100 mg | 10 mL | 20 mL |
How do you reconstitute GHK-Cu?
- Concentration: 50 mg ÷ 3 mL = 16.667 mg/mL (166.67 mcg per unit).
- Volume to draw: 1 mg ÷ 16.667 mg/mL = 0.06 mL.
- Syringe units: 0.06 mL × 100 = 6 units on a U-100 syringe.
Example numbers only. They come from the default vial, water and amount above, not a recommendation.
What else do people ask about GHK-Cu?
How many units is 1 mg of GHK-Cu?
It depends on how much water is in the vial. With a 50 mg vial and 3 mL of water, 1 mg is 6 units (0.06 mL) on a U-100 syringe. Change the vial or water amount above to see your number.
How much bacteriostatic water do I add to a GHK-Cu vial?
There's no single right amount. More water makes each unit weaker and the draw bigger, which is easier to measure. Less water makes the draw smaller. Many people pick an amount that puts their dose on a round number of units. The "Units → water to add" tab and the table above work this out.
How many doses are in a 50 mg GHK-Cu vial?
At 1 mg per dose, a 50 mg vial holds 50 doses. The amount of water doesn't change this.
Does this page recommend a GHK-Cu dose?
No. This page only converts amounts you enter into syringe units. Ask a licensed clinician about whether and how to use GHK-Cu.
