GLP-1 weight loss calculator

You are trying to work out how much to draw or when to step up.

Standard titration schedules for the main GLP-1 medications are shown below, taken from each product's prescribing information. Use the converter to translate a dose in milligrams into syringe units at a given concentration.

Vial concentration (mg/mL)

12.5units on a U-100 syringe

= 0.125 mL · 2.5 mg at 20 mg/mL

Check the concentration printed on the vial you are actually holding. The same dose in milligrams is a completely different mark on the syringe at a different concentration. If the number here does not match what your prescriber told you, trust your prescriber.

Dose escalation exists to reduce gastrointestinal side effects, not to reach a target faster. The schedules above are the labelled defaults — prescribers routinely hold patients at a step longer, and some people stay on a lower maintenance dose indefinitely. Any change to your own schedule is a decision for the person who wrote your prescription.
