Cagrilintide Reconstitution Calculator
Enter your vial size, BAC water volume, and target dose in mg. The calculator returns exact insulin units, mg/mL concentration, doses per vial, and a draw-to-here syringe diagram. It does not recommend a dose or schedule.
Peptide Reconstitution Calculator
Calculate your exact dose
Enter your vial details to calculate how many units to draw for your dose.
Common doses: Semaglutide (0.25-2.4mg), Tirzepatide (2.5-15mg)
This calculator is for informational purposes only, so always double-check your result with a healthcare provider. We assume no liability for dosing errors.
How to use it
How to use this calculator
- 01
Enter vial size
5mg or 10mg are the common gray-market cagrilintide vial sizes
- 02
Enter BAC water volume
1 to 3mL is typical; more water spreads a small dose across more syringe units
- 03
Enter your target dose in mg
The calculator converts to insulin units - it does not recommend a dose
- 04
Pick your syringe
U-100 insulin syringe in 0.3, 0.5, or 1.0mL - the visualizer shows the exact fill line
Dose Calculation: The Math
The formula is the same for any reconstituted peptide:
Worked example. A 10mg vial reconstituted with 2mL of BAC water has a concentration of 10 ÷ 2 = 5 mg/mL. To draw 1mg: (1 ÷ 5) × 100 = 20 units on a U-100 insulin syringe.
Example Amounts for Converting to Units
The rows below are example amounts for converting to units, not a dosing schedule or recommendation. Cagrilintide monotherapy dosing is not standardized outside of clinical trials. Verify any dose with your provider.
5mg Vial + 1mL BAC Water (5.0 mg/mL)
| Amount | Units to Draw | Draws Per Vial |
|---|---|---|
| 0.5 mg | 10 units | 10 |
| 1.0 mg | 20 units | 5 |
| 1.5 mg | 30 units | 3 |
| 2.0 mg | 40 units | 2 |
| 2.4 mg | 48 units | 2 |
10mg Vial + 2mL BAC Water (5.0 mg/mL)
| Amount | Units to Draw | Draws Per Vial |
|---|---|---|
| 0.5 mg | 10 units | 20 |
| 1.0 mg | 20 units | 10 |
| 1.5 mg | 30 units | 6 |
| 2.0 mg | 40 units | 5 |
| 2.4 mg | 48 units | 4 |
Storage After Reconstitution
Reconstituted cagrilintide is generally treated with the same 28 to 30 day refrigerated window used for other reconstituted peptides - 36 to 46°F (2 to 8°C), upright, out of light, never frozen. Discard if the solution becomes cloudy, develops particles, or changes color. Choose a vial size you can finish inside that window at your current draw frequency.
Mixing Steps
- Swab the tops of both the cagrilintide vial and the BAC water vial with alcohol. Let them dry, about 15 to 30 seconds.
- Draw your chosen volume of BAC water (typically 1 to 3mL) into an insulin syringe.
- Insert the needle into the cagrilintide vial at an angle and let the water run slowly down the inside glass wall. Do not aim directly at the powder.
- Gently swirl or roll the vial between your palms until fully dissolved. Do not shake.
- Check the solution. It should be completely clear with no particles or cloudiness before you draw.
