GLP-1 Injection
Dose Calculator

About This Tool

This is a free, independent calculator built to help people on GLP-1 medications — like compounded tirzepatide and semaglutide — convert their prescribed dose into the correct number of syringe units to draw.

GLP-1 medications are increasingly prescribed for type 2 diabetes and weight management. Compounded versions from specialty pharmacies are drawn from multi-dose vials, which requires manual calculation. We built this tool to make that easier and reduce the chance of dosing errors.

This site is not affiliated with any pharmaceutical company, pharmacy, or healthcare provider. It is an independent educational resource.

Accuracy

The calculator uses the standard formula: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL), then multiplies by your syringe's units per mL. Results should always be verified against your prescription label and confirmed with your provider.
