Mixing table for a 50 mg vial
What each mark on a U-100 insulin syringe holds. With 5 mL of water, for example, the vial holds 10 mg/mL, so every unit is 100 mcg and 10 units is 1 mg.
| Water | Strength | 1 unit | 10 units |
|---|---|---|---|
| 3 mL | 16.667 mg/mL | 166.67 mcg | 1.67 mg |
| 5 mL | 10 mg/mL | 100 mcg | 1 mg |
| 6 mL | 8.333 mg/mL | 83.33 mcg | 833.33 mcg |
| 10 mL | 5 mg/mL | 50 mcg | 500 mcg |
More water doesn't change the dose, only how much liquid holds it. It makes small doses easier to measure. On a U-100 syringe, 100 units = 1 mL.
How to mix a GHK-Cu vial
- Wash your hands. Wipe the tops of the peptide vial and the water vial with an alcohol swab and let them dry.
- Draw up the amount of bacteriostatic water you've chosen with a fresh syringe.
- Push the needle through the rubber top and let the water run slowly down the inside wall, not straight onto the powder.
- Swirl or roll the vial gently until the powder dissolves. Don't shake it.
- Label the vial with the date and strength, and keep it in the fridge.
- Use a new sterile syringe for every dose, and never share needles.
