GHK-Cu: 50 mg vial with 1 mL water
Quick answer
Adding 1 mL of bacteriostatic water to a 50 mg GHK-Cu vial gives 50 mg/mL (50000 mcg/mL), so each unit on a U-100 insulin syringe holds 500 mcg. A 500 mcg dose is 1 units (0.01 mL), and the vial holds about 100 doses of that size.
Concentration
- Vial: 50 mg GHK-Cu
- Bacteriostatic water: 1 mL
- Concentration: 50 mg/mL (50000 mcg/mL)
- 1 unit on a U-100 syringe = 500 mcg
GHK-Cu dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 1 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 50000 |
| 1.5 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 33333 |
| 2 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 25000 |
| 500 mcg | 1 units | 0.01 mL | 100 |
| 750 mcg | 1.5 units | 0.015 mL | 66 |
| 1 mg | 2 units | 0.02 mL | 50 |
| 1.5 mg | 3 units | 0.03 mL | 33 |
| 2 mg | 4 units | 0.04 mL | 25 |

Common questions
How many units is 500 mcg of GHK-Cu from a 50 mg vial with 1 mL water?
500 mcg is 1 units (0.01 mL) on a U-100 insulin syringe. With 1 mL of water in a 50 mg vial, each unit holds 500 mcg. For comparison: 750 mcg = 1.5 units, 1 mg = 2 units, 1.5 mg = 3 units.
What is the concentration of a 50 mg GHK-Cu vial mixed with 1 mL of water?
50 mg divided by 1 mL is 50 mg/mL, or 50000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 500 mcg per unit.
How many 500 mcg doses are in a 50 mg vial?
About 100. The water volume changes how many units each dose takes, not how many doses the vial holds.
How much water should I add to a 50 mg GHK-Cu vial?
The Crestigen GHK-Cu protocol uses 3 mL. 1 mL works too as long as you calculate units for this concentration (50 mg/mL) and label the vial.
