Mod GRF 1-29: 2 mg vial with 1 mL water
Quick answer
Adding 1 mL of bacteriostatic water to a 2 mg Mod GRF 1-29 vial gives 2 mg/mL (2000 mcg/mL), so each unit on a U-100 insulin syringe holds 20 mcg. A 100 mcg dose is 5 units (0.05 mL), and the vial holds about 20 doses of that size.
Concentration
- Vial: 2 mg Mod GRF 1-29
- Bacteriostatic water: 1 mL
- Concentration: 2 mg/mL (2000 mcg/mL)
- 1 unit on a U-100 syringe = 20 mcg

Common questions
How many units is 100 mcg of Mod GRF 1-29 from a 2 mg vial with 1 mL water?
100 mcg is 5 units (0.05 mL) on a U-100 insulin syringe. With 1 mL of water in a 2 mg vial, each unit holds 20 mcg. For comparison: 50 mcg = 2.5 units, 200 mcg = 10 units, 250 mcg = 12.5 units.
What is the concentration of a 2 mg Mod GRF 1-29 vial mixed with 1 mL of water?
2 mg divided by 1 mL is 2 mg/mL, or 2000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 20 mcg per unit.
How many 100 mcg doses are in a 2 mg vial?
About 20. 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 Mod GRF 1-29 vial?
The Crestigen Mod GRF 1-29 protocol uses 2 mL. 1 mL works too as long as you calculate units for this concentration (2 mg/mL) and label the vial.
