Cagrilintide peptide calculator
Pre-filled Cagrilintide dosage and reconstitution math: a 5 mg vial, 2 ml of bacteriostatic water, and the resulting U-100 insulin-syringe units. Adjust the inputs below or open the full calculator.
How to reconstitute Cagrilintide
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the Cagrilintide vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Store the reconstituted vial refrigerated (2–8 °C / 36–46 °F) and use within roughly 28 days.
- Draw each dose to the unit mark shown above for your target 450 mcg dose.
About Cagrilintide
Cagrilintide is a long-acting amylin analog developed for once-weekly subcutaneous dosing. It is being studied primarily in combination with semaglutide (CagriSema) for obesity and type 2 diabetes.
Half-life: Approximately 6 days (once-weekly dosing)
Typical dose range: Trial titration: 0.16 → 0.30 → 0.60 → 1.2 → 2.4 mg weekly
Class: Long-acting amylin analog
Cagrilintide calculator FAQ
Is this a Cagrilintide peptide calculator or a reconstitution calculator?
Both. This Cagrilintide calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 5 mg Cagrilintide vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 5 mg Cagrilintide vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 450 mcg Cagrilintide dose?
With the default 5 mg vial and 2 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 450 mcg dose. Change the dose if your protocol uses a different amount.
Does this Cagrilintide dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether Cagrilintide is appropriate are clinical decisions that should be made with a licensed healthcare professional.
