Use this cagrilintide dosage calculator to convert vial strength, BAC water volume, and target dose into the exact amount to draw in mL and syringe units. Cagrilintide is a long-acting amylin analogue often discussed alongside GLP-1 compounds; this page covers the math, not dosing decisions.
- Common vial examples
- 5 / 10 mg
- Example dose
- 1.2 mg
- Common syringe
- U-100 insulin

Storage before and after reconstitution: Lyophilised 2–8°C; reconstituted vial refrigerated and protected from light.
Quick answers: Cagrilintide doses in units
With a 5 mg vial mixed with 2 mL of bacteriostatic water (2.5 mg/mL), on a U-100 insulin syringe:
- How many units is 1.2 mg of cagrilintide?
- 48 units (0.48 mL)
- How many units is 2.4 mg of cagrilintide?
- 96 units (0.96 mL)
- How many units is 4.5 mg of cagrilintide?
- 180 units (1.8 mL), more than one 1 mL syringe

Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 1.2 mg dose is 0.48 mL, which equals 48 units on a U-100 syringe.

U-100 units to draw for each common Cagrilintide dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 1.2 mg | 2.4 mg | 4.5 mg |
|---|---|---|---|---|
| 5 mg | 2.5 mg/mL | 48 u(0.48 mL) | 96 u(0.96 mL) | 180 u(1.8 mL) |
| 10 mg | 5 mg/mL | 24 u(0.24 mL) | 48 u(0.48 mL) | 90 u(0.9 mL) |

How the cagrilintide calculation works
Cagrilintide is labelled in milligrams while weekly doses are usually discussed in milligrams or micrograms. The calculator converts the vial total to mcg, divides by your BAC water volume for concentration, then divides your target dose by that concentration.
- 5 mg vial = 5,000 mcg total
- 5,000 mcg / 2 mL = 2,500 mcg per mL
- 1,200 mcg target = 0.48 mL draw
Cagrilintide 5 mg vial with 2 mL example
A 5 mg cagrilintide vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.
A 1.2 mg (1,200 mcg) dose is 0.48 mL, which equals 48 units on a U-100 syringe. A 2.4 mg dose doubles to 0.96 mL, or 96 units.
- 5 mg / 2 mL = 2.5 mg/mL
- 1,200 mcg / 2,500 mcg per mL = 0.48 mL = 48 units
- 2,400 mcg / 2,500 mcg per mL = 0.96 mL = 96 units

How much BAC water for a 10 mg cagrilintide vial
A 10 mg vial in 2 mL gives 5 mg/mL, so a 1.2 mg dose is 0.24 mL (24 units), 2.4 mg is 0.48 mL (48 units) and 4.5 mg is 0.9 mL (90 units) — every step of a typical titration fits a 1 mL syringe.
In 3 mL the vial is about 3.33 mg/mL: 1.2 mg becomes 36 units and 2.4 mg 72 units, but 4.5 mg (135 units) no longer fits a 1 mL syringe. A 10 mg vial holds about eight 1.2 mg doses or four 2.4 mg doses.
- 10 mg / 2 mL = 5 mg/mL → 1.2 mg = 24 units, 2.4 mg = 48 units, 4.5 mg = 90 units
- 10 mg / 3 mL = 3.33 mg/mL → 1.2 mg = 36 units, 2.4 mg = 72 units
- About eight 1.2 mg doses or four 2.4 mg doses per vial

Titrating cagrilintide
Cagrilintide is studied across a wide weekly range, so doses step up over time. Pick a BAC water volume that keeps both early and later doses on readable unit marks, and re-run the calculator each time you change the target.
- More BAC water = lower concentration = more units per dose
- Re-check the units each time you step the dose up
- Keep larger doses within your syringe's capacity
