IGF-1 LR3: 1 mg vial with 1 mL water
Quick answer
Adding 1 mL of bacteriostatic water to a 1 mg IGF-1 LR3 vial gives 1 mg/mL (1000 mcg/mL), so each unit on a U-100 insulin syringe holds 10 mcg. A 20 mcg dose is 2 units (0.02 mL), and the vial holds about 50 doses of that size.
Concentration
- Vial: 1 mg IGF-1 LR3
- Bacteriostatic water: 1 mL
- Concentration: 1 mg/mL (1000 mcg/mL)
- 1 unit on a U-100 syringe = 10 mcg
IGF-1 LR3 dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 20 mcg (protocol dose) | 2 units | 0.02 mL | 50 |
| 40 mcg (protocol dose) | 4 units | 0.04 mL | 25 |
| 50 mcg (protocol dose) | 5 units | 0.05 mL | 20 |
| 100 mcg | 10 units | 0.1 mL | 10 |
| 200 mcg | 20 units | 0.2 mL | 5 |
| 250 mcg | 25 units | 0.25 mL | 4 |
| 300 mcg | 30 units | 0.3 mL | 3 |
| 500 mcg | 50 units | 0.5 mL | 2 |
Units on a U-100 insulin syringe (100 units = 1 mL).
Common questions
How many units is 20 mcg of IGF-1 LR3 from a 1 mg vial with 1 mL water?
20 mcg is 2 units (0.02 mL) on a U-100 insulin syringe. With 1 mL of water in a 1 mg vial, each unit holds 10 mcg. For comparison: 40 mcg = 4 units, 50 mcg = 5 units, 100 mcg = 10 units.
What is the concentration of a 1 mg IGF-1 LR3 vial mixed with 1 mL of water?
1 mg divided by 1 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 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. 1 mL works too as long as you calculate units for this concentration (1 mg/mL) and label the vial.
