GHK-Cu concentration chart
Concentration for common vial sizes at 1, 2, 3 and 5 mL of water, with the amount held in every 10 units of a U-100 syringe.
| Vial | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 50 mg | 50 mg/mL · 5 mg per 10 units | 25 mg/mL · 2.5 mg per 10 units | 16.67 mg/mL · 1.667 mg per 10 units | 10 mg/mL · 1 mg per 10 units |
| 100 mg | 100 mg/mL · 10 mg per 10 units | 50 mg/mL · 5 mg per 10 units | 33.33 mg/mL · 3.333 mg per 10 units | 20 mg/mL · 2 mg per 10 units |
Units per 1 mg of GHK-Cu
How many units on a U-100 syringe hold 1 mg, for each vial size and water volume. 1 mg is a round reference amount for scaling, not a dose: multiply or divide to match the dose on your prescription, or use the calculator.
| Vial | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 50 mg | 2 units | 4 units | 6 units | 10 units |
| 100 mg | 1 unit · too small to read reliably | 2 units | 3 units | 5 units |
Questions
How do I calculate GHK-Cu units on a syringe?
Divide the mg in the vial by the mL of water added to get mg/mL. Divide your prescribed dose by that figure for mL, then multiply by 100 for units on a U-100 syringe. For example, a 100 mg vial with 2 mL of water is 50 mg/mL, so every 10 units holds 5 mg.
How many units is 1 mg of GHK-Cu?
It depends on the vial size and the water added. With a 100 mg vial, 1 mg is 1 unit after 1 mL of water, 2 units after 2 mL of water, 3 units after 3 mL of water. The lookup table above covers the other vial sizes.
Is GHK-Cu measured in mg or mcg?
GHK-Cu vials are labelled in mg. If your prescription is written in mcg, divide by 1,000 to get mg, or switch the dose field to mcg. In a 100 mg vial mixed with 2 mL, one unit on the syringe holds 0.5 mg (500 mcg).
How much bacteriostatic water do I add to GHK-Cu?
Follow the amount on your pharmacy label. The volume of water does not change how much GHK-Cu is in the vial; it only changes how many units a given dose takes up. Enter whatever amount was actually added.
What GHK-Cu dose should I enter?
The dose written on your prescription. This page converts a dose into syringe units and does not recommend one.
