Cagrilintide Dosing Calculator & Reconstitution Guide
A long-acting amylin analog researched for weight management.
Cagrilintide is a research peptide. A long-acting amylin analog researched for weight management. To dose it, reconstitute the vial (for example 5 mg in 2 mL of bacteriostatic water for 2.5 mg/mL), then divide your target dose by that concentration to find the units to draw.

What is Cagrilintide?
Cagrilintide is a long-acting amylin analog studied for appetite regulation and weight loss, often paired with a GLP-1 receptor agonist such as semaglutide. It is dosed once weekly and titrated upward, expressed in milligrams. Also known as cagri.
How many units is each Cagrilintide dose?
| Dose | Volume to draw | Units (U-100) |
|---|---|---|
| 0.3 mg | 0.12 mL | 12 units |
| 0.6 mg | 0.24 mL | 24 units |
| 1.2 mg | 0.48 mL | 48 units |
| 2.4 mg | 0.96 mL | 96 units |
Based on a 5 mg vial reconstituted with 2 mL of bacteriostatic water (2.5 mg/mL) and a U-100 insulin syringe. The dose amounts shown are commonly reported by the community and in anecdotal research, not recommendations or medical advice; only the reconstitution math (volume and units) is calculated for you.
How to calculate a Cagrilintide dose
- 1
Choose your vial and water
Select your Cagrilintide vial size (for example 5 mg) and the volume of bacteriostatic water you will add (for example 2 mL).
- 2
Find the concentration
Divide vial milligrams by water volume. 5 mg in 2 mL gives 2.5 mg/mL.
- 3
Calculate the draw
Divide your target dose by the concentration to get the volume in mL, then multiply by 100 to get units on a U-100 insulin syringe.
- 4
Verify on the syringe
Use the Keel calculator to see the exact draw rendered on a to-scale syringe, with a warning if the dose exceeds the syringe capacity.
Cagrilintide dosing FAQ
How do I reconstitute Cagrilintide?
A common approach is to add 2 mL of bacteriostatic water to a 5 mg vial, which gives 2.5 mg/mL. Add the water slowly down the vial wall, swirl gently rather than shaking, and let the powder dissolve fully before drawing.
How many units is 0.3 mg of Cagrilintide?
At 2.5 mg/mL, 0.3 mg equals 0.12 mL, which is 12 units on a U-100 insulin syringe.
What Cagrilintide doses do people report?
Community and anecdotal reports commonly cite 0.3 to 2.4 mg. These are figures people report, not a recommendation from Keel. Cagrilintide is a long-acting amylin analog studied for appetite regulation and weight loss, often paired with a GLP-1 receptor agonist such as semaglutide. It is dosed once weekly and titrated upward, expressed in milligrams.
Which insulin syringe should I use for Cagrilintide?
A U-100 insulin syringe is standard. A 0.3 mL (30-unit) syringe gives the most precise measurement for small draws, while a 0.5 mL or 1 mL syringe is better when the draw exceeds 30 units. Keel warns you when a dose is larger than the syringe you select.
How should I store Cagrilintide after reconstitution?
Reconstituted peptides are generally kept refrigerated and protected from light, with the unmixed powder stored cooler still. Follow the guidance from your supplier or a licensed healthcare professional for the specific compound.
What if my Cagrilintide dose is larger than the syringe holds?
Either use a larger insulin syringe or reconstitute with more bacteriostatic water to lower the concentration, which increases the volume per dose so it fits. Keel flags an over-draw and you can adjust the inputs until the draw fits.
Is Cagrilintide dosing the same for everyone?
No. The right draw depends on your vial size, how much bacteriostatic water you add, and your target dose. Always recalculate when any of those change, and consult a licensed healthcare professional.
