GHK-Cu: 50 mg vial with 2 mL water
Quick answer
Adding 2 mL of bacteriostatic water to a 50 mg GHK-Cu vial gives 25 mg/mL (25000 mcg/mL), so each unit on a U-100 insulin syringe holds 250 mcg. A 250 mcg dose is 1 units (0.01 mL), and the vial holds about 200 doses of that size.
Concentration
- Vial: 50 mg GHK-Cu
- Bacteriostatic water: 2 mL
- Concentration: 25 mg/mL (25000 mcg/mL)
- 1 unit on a U-100 syringe = 250 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 |
| 250 mcg | 1 units | 0.01 mL | 200 |
| 300 mcg | 1.2 units | 0.012 mL | 166 |
| 500 mcg | 2 units | 0.02 mL | 100 |
| 750 mcg | 3 units | 0.03 mL | 66 |
| 1 mg | 4 units | 0.04 mL | 50 |

Common questions
How many units is 250 mcg of GHK-Cu from a 50 mg vial with 2 mL water?
250 mcg is 1 units (0.01 mL) on a U-100 insulin syringe. With 2 mL of water in a 50 mg vial, each unit holds 250 mcg. For comparison: 300 mcg = 1.2 units, 500 mcg = 2 units, 750 mcg = 3 units.
What is the concentration of a 50 mg GHK-Cu vial mixed with 2 mL of water?
50 mg divided by 2 mL is 25 mg/mL, or 25000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 250 mcg per unit.
How many 250 mcg doses are in a 50 mg vial?
About 200. 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. 2 mL works too as long as you calculate units for this concentration (25 mg/mL) and label the vial.
