Each row is one dose, the volume to draw and where that sits on a U-100 insulin syringe. The last three columns show which syringe sizes can hold it in one draw.
| Dose | Volume | Syringe units | 0.3 mL syringe | 0.5 mL syringe | 1 mL syringe |
|---|---|---|---|---|---|
| 100 mcg | 0.10 mL | 10 units | Yes | Yes | Yes |

How to mix a 2 mg Gonadorelin vial
- Wash your hands. Wipe the stopper of the Gonadorelin vial and the water vial with an alcohol swab.
- Draw 2 mL of bacteriostatic water into a syringe.
- Push the needle through the stopper of the peptide vial and let the water run slowly down the glass, not straight onto the powder.
- Swirl the vial gently until the powder is gone. Do not shake it.
- Write the date and 1 mg/mL on the vial, then put it in the fridge.
If you add a different amount of water
More water makes each dose a bigger, easier draw. Less water makes it smaller. The milligrams in the vial do not change.
| Water added | Concentration | 100 mcg | 200 mcg |
|---|---|---|---|
| 1 mL | 2 mg/mL | 5 units | 10 units |
| 2 mL | 1 mg/mL | 10 units | 20 units |
| 3 mL | 0.6667 mg/mL | 15 units | 30 units |
The marked row is the amount used in the chart above. Red cells are draws under 5 units, which are hard to read, or over 100 units, which one 1 mL syringe cannot hold.
How many doses are in the vial
| Dose | Whole doses in a 2 mg vial |
|---|---|
| 100 mcg | 20 doses |
| 200 mcg | 10 doses |
How long the vial lasts depends on how often it is used. The reported frequency for Gonadorelin is: 2 to 3 times weekly.
