Cerebrolysin: 60 mg vial with 3 mL water
Quick answer
Adding 3 mL of bacteriostatic water to a 60 mg Cerebrolysin vial gives 20 mg/mL (20000 mcg/mL), so each unit on a U-100 insulin syringe holds 200 mcg. A 20 mg dose is 100 units (1 mL), and the vial holds about 3 doses of that size.
Concentration
- Vial: 60 mg Cerebrolysin
- Bacteriostatic water: 3 mL (the volume in the Crestigen protocol)
- Concentration: 20 mg/mL (20000 mcg/mL)
- 1 unit on a U-100 syringe = 200 mcg
Cerebrolysin dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 200 mcg | 1 units | 0.01 mL | 300 |
| 250 mcg | 1.3 units | 0.013 mL | 240 |
| 300 mcg | 1.5 units | 0.015 mL | 200 |
| 500 mcg | 2.5 units | 0.025 mL | 120 |
| 20 mg (protocol dose) | 100 units | 1 mL | 3 |
| 24 mg (protocol dose) | more than 1 mL (1.2 mL), too much for one U-100 syringe | 1.2 mL | 2 |
| 28 mg (protocol dose) | more than 1 mL (1.4 mL), too much for one U-100 syringe | 1.4 mL | 2 |
| 32 mg (protocol dose) | more than 1 mL (1.6 mL), too much for one U-100 syringe | 1.6 mL | 1 |

Common questions
How many units is 20 mg of Cerebrolysin from a 60 mg vial with 3 mL water?
20 mg is 100 units (1 mL) on a U-100 insulin syringe. With 3 mL of water in a 60 mg vial, each unit holds 200 mcg. For comparison: 250 mcg = 1.3 units, 300 mcg = 1.5 units, 500 mcg = 2.5 units.
What is the concentration of a 60 mg Cerebrolysin vial mixed with 3 mL of water?
60 mg divided by 3 mL is 20 mg/mL, or 20000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 200 mcg per unit.
How many 20 mg doses are in a 60 mg vial?
About 3. 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 60 mg Cerebrolysin vial?
3 mL is the volume used in the Crestigen Cerebrolysin protocol. More water makes each dose a larger, easier-to-measure number of units; less water keeps injections smaller.
