Your reconstitution is set — now track your cagrilintide protocol.
Regimen logs every cagrilintide injection — 1mg at a time, 10 doses per vial. It reminds you when to inject, tracks your reconstitution dates, and logs weight and side effects alongside your protocol.
- Injection reminders for each compound
- Track reconstitution dates and vial expiry
- Track weight, side effects, and protocol over time

Dose Calculation: The Math
The formula is the same for any reconstituted peptide:
Concentration = Total peptide (mg) ÷ BAC water added (mL)
Units = (Target dose in mg ÷ Concentration in mg/mL) × 100
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.
Frequently Asked Questions
What is cagrilintide?
Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. It is not a GLP-1. It is being studied in combination with semaglutide (CagriSema) in Phase 3 trials for weight management. Cagrilintide is investigational and not FDA approved.
How much BAC water do I mix with a 5mg cagrilintide vial?
A common choice is 1mL, which gives a 5 mg/mL concentration. That makes 1mg equal to 20 units and 2mg equal to 40 units on a U-100 insulin syringe. Some people use 2mL (2.5 mg/mL) if they want lower doses to sit higher on the barrel for easier reading.
How much BAC water for a 10mg cagrilintide vial?
2mL is standard, giving 5 mg/mL: 1mg equals 20 units and 2mg equals 40 units. 1mL gives 10 mg/mL: 1mg is 10 units and 2mg is 20 units. Match your BAC water volume to the dose you plan to draw so the mark is easy to read on your syringe.
What syringe should I use for cagrilintide?
A U-100 insulin syringe is standard. Pick the barrel size by dose volume: 0.3mL (30 units) for the smallest draws, 0.5mL (50 units) for typical draws, and 1.0mL (100 units) for larger ones. All U-100 syringes use the same 100 units = 1mL calibration.
How long is reconstituted cagrilintide stable?
As with other reconstituted peptides, the working guideline is 28 to 30 days refrigerated between 36 and 46°F (2 to 8°C). Keep the vial upright, away from light, and never freeze it. Discard if the solution becomes cloudy or discolored. Match vial size to how quickly you will finish it inside that window.
Is there an established cagrilintide monotherapy dosing schedule?
No — cagrilintide monotherapy dosing is not settled. The published Phase 3 program is CagriSema, a fixed combination with semaglutide, and single-agent cagrilintide dosing outside those trials is not standardized. This calculator does not recommend a dose or schedule. Work with a licensed clinician on any dose or titration decisions.
