CJC-1295 Calculator
Enter your CJC-1295 vial size, the water you add and your dose to get the units to draw on a U-100 syringe. The units chart and water table below cover 2, 5, 10 mg vials.
How many units is each CJC-1295 dose?
Units on a U-100 insulin syringe for common amounts, with 2 mL of bacteriostatic water in the vial. With a different water amount, use the calculator above.
| Dose (mcg) | 2 mg vial + 2 mL | 5 mg vial + 2 mL | 10 mg vial + 2 mL |
|---|---|---|---|
| 100 mcg | 10 units 0.1 mL | 4 units 0.04 mL | 2 units 0.02 mL |
| 300 mcg | 30 units 0.3 mL | 12 units 0.12 mL | 6 units 0.06 mL |
| 500 mcg | 50 units 0.5 mL | 20 units 0.2 mL | 10 units 0.1 mL |
| 1000 mcg | 100 units 1 mL | 40 units 0.4 mL | 20 units 0.2 mL |
| 2000 mcg | 200 units* 2 mL | 80 units 0.8 mL | 40 units 0.4 mL |
* More than one 1 mL syringe. Use more water or split the draw.
How much bac water for CJC-1295?
Water only changes how much liquid each dose takes up, not how much CJC-1295 is in it. To land a 100 mcg dose on a round number of units, add:
| Vial | So 100 mcg = 10 units | So 100 mcg = 20 units |
|---|---|---|
| 2 mg | 2 mL | 4 mL |
| 5 mg | 5 mL | 10 mL |
| 10 mg | 10 mL | 20 mL |
How do you reconstitute CJC-1295?
- Concentration: 5 mg ÷ 2 mL = 2.5 mg/mL (25 mcg per unit).
- Volume to draw: 100 mcg ÷ 2.5 mg/mL = 0.04 mL.
- Syringe units: 0.04 mL × 100 = 4 units on a U-100 syringe.
Example numbers only. They come from the default vial, water and amount above, not a recommendation.
What else do people ask about CJC-1295?
How many units is 100 mcg of CJC-1295?
It depends on how much water is in the vial. With a 5 mg vial and 2 mL of water, 100 mcg is 4 units (0.04 mL) on a U-100 syringe. Change the vial or water amount above to see your number.
How much bacteriostatic water do I add to a CJC-1295 vial?
There's no single right amount. More water makes each unit weaker and the draw bigger, which is easier to measure. Less water makes the draw smaller. Many people pick an amount that puts their dose on a round number of units. The "Units → water to add" tab and the table above work this out.
How many doses are in a 5 mg CJC-1295 vial?
At 100 mcg per dose, a 5 mg vial holds 50 doses. The amount of water doesn't change this.
Does this page recommend a CJC-1295 dose?
No. This page only converts amounts you enter into syringe units. Ask a licensed clinician about whether and how to use CJC-1295.
