IGF-1 LR3: 1 mg vial with 2 mL water
Quick answer
Adding 2 mL of bacteriostatic water to a 1 mg IGF-1 LR3 vial gives 0.5 mg/mL (500 mcg/mL), so each unit on a U-100 insulin syringe holds 5 mcg. A 20 mcg dose is 4 units (0.04 mL), and the vial holds about 50 doses of that size.
Concentration
- Vial: 1 mg IGF-1 LR3
- Bacteriostatic water: 2 mL
- Concentration: 0.5 mg/mL (500 mcg/mL)
- 1 unit on a U-100 syringe = 5 mcg
IGF-1 LR3 dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 20 mcg (protocol dose) | 4 units | 0.04 mL | 50 |
| 40 mcg (protocol dose) | 8 units | 0.08 mL | 25 |
| 50 mcg (protocol dose) | 10 units | 0.1 mL | 20 |
| 100 mcg | 20 units | 0.2 mL | 10 |
| 200 mcg | 40 units | 0.4 mL | 5 |
| 250 mcg | 50 units | 0.5 mL | 4 |
| 300 mcg | 60 units | 0.6 mL | 3 |
| 500 mcg | 100 units | 1 mL | 2 |

Common questions
How many units is 20 mcg of IGF-1 LR3 from a 1 mg vial with 2 mL water?
20 mcg is 4 units (0.04 mL) on a U-100 insulin syringe. With 2 mL of water in a 1 mg vial, each unit holds 5 mcg. For comparison: 40 mcg = 8 units, 50 mcg = 10 units, 100 mcg = 20 units.
What is the concentration of a 1 mg IGF-1 LR3 vial mixed with 2 mL of water?
1 mg divided by 2 mL is 0.5 mg/mL, or 500 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 5 mcg per unit.
How many 20 mcg doses are in a 1 mg vial?
About 50. 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 1 mg IGF-1 LR3 vial?
The Crestigen IGF-1 LR3 protocol uses 3 mL. 2 mL works too as long as you calculate units for this concentration (0.5 mg/mL) and label the vial.
