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.
Reconstitution reference
U100 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) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
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
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
