Gonadorelin: 2 mg vial with 2 mL water

Quick answer

Adding 2 mL of bacteriostatic water to a 2 mg Gonadorelin vial gives 1 mg/mL (1000 mcg/mL), so each unit on a U-100 insulin syringe holds 10 mcg. A 50 mcg dose is 5 units (0.05 mL), and the vial holds about 40 doses of that size.

Concentration

• Vial: 2 mg Gonadorelin
• Bacteriostatic water: 2 mL (the volume in the Crestigen protocol)
• Concentration: 1 mg/mL (1000 mcg/mL)
• 1 unit on a U-100 syringe = 10 mcg

Common questions

How many units is 50 mcg of Gonadorelin from a 2 mg vial with 2 mL water?

50 mcg is 5 units (0.05 mL) on a U-100 insulin syringe. With 2 mL of water in a 2 mg vial, each unit holds 10 mcg. For comparison: 100 mcg = 10 units, 200 mcg = 20 units, 250 mcg = 25 units.

What is the concentration of a 2 mg Gonadorelin vial mixed with 2 mL of water?

2 mg divided by 2 mL is 1 mg/mL, or 1000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 10 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?

2 mL is the volume used in the Crestigen Gonadorelin protocol. More water makes each dose a larger, easier-to-measure number of units; less water keeps injections smaller.
