Gonadorelin: 2 mg vial with 3 mL water
Quick answer
Adding 3 mL of bacteriostatic water to a 2 mg Gonadorelin vial gives 0.67 mg/mL (666.7 mcg/mL), so each unit on a U-100 insulin syringe holds 6.7 mcg. A 50 mcg dose is 7.5 units (0.075 mL), and the vial holds about 40 doses of that size.
Concentration
- Vial: 2 mg Gonadorelin
- Bacteriostatic water: 3 mL
- Concentration: 0.67 mg/mL (666.7 mcg/mL)
- 1 unit on a U-100 syringe = 6.7 mcg
Gonadorelin dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 50 mcg (protocol dose) | 7.5 units | 0.075 mL | 40 |
| 100 mcg (protocol dose) | 15 units | 0.15 mL | 20 |
| 200 mcg | 30 units | 0.3 mL | 10 |
| 250 mcg | 37.5 units | 0.375 mL | 8 |
| 300 mcg | 45 units | 0.45 mL | 6 |
| 500 mcg | 75 units | 0.75 mL | 4 |
Units on a U-100 insulin syringe (100 units = 1 mL).
Common questions
How many units is 50 mcg of Gonadorelin from a 2 mg vial with 3 mL water?
50 mcg is 7.5 units (0.075 mL) on a U-100 insulin syringe. With 3 mL of water in a 2 mg vial, each unit holds 6.7 mcg. For comparison: 100 mcg = 15 units, 200 mcg = 30 units, 250 mcg = 37.5 units.
What is the concentration of a 2 mg Gonadorelin vial mixed with 3 mL of water?
2 mg divided by 3 mL is 0.67 mg/mL, or 666.7 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 6.7 mcg per unit.
How many 50 mcg doses are in a 2 mg vial?
About 40. 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 2 mg Gonadorelin vial?
The Crestigen Gonadorelin protocol uses 2 mL. 3 mL works too as long as you calculate units for this concentration (0.67 mg/mL) and label the vial.
