For compounded semaglutide and tirzepatide. Tap your prescribed mg dose and read the units to draw.
For compounded semaglutide and tirzepatide dosed in milligrams. Enter the vial total and your water, tap your prescribed dose, and read the units to draw on a U-100 syringe.
About the glp-1 dose calculator
Compounded semaglutide and tirzepatide are supplied as a powder dosed in milligrams, so you reconstitute the vial and then convert your prescribed mg dose into syringe units, the same arithmetic as any peptide, framed for GLP-1 titration.
Enter the vial total and the bacteriostatic water you added, then tap a preset dose. The presets cover the standard semaglutide ladder (0.25 to 2.4 mg) and the tirzepatide ladder (2.5 to 15 mg). The calculator returns the units to draw, the volume, and how many doses the vial holds.
If you are tracking a brand product, the Zepbound, semaglutide, and tirzepatide guides explain the titration schedule, and the Redose app logs each weekly shot and rotates your injection sites automatically.
FAQ
How do I calculate a semaglutide or tirzepatide dose in units?
Reconstitute the vial, divide the vial mg by the water mL to get concentration, then divide your prescribed mg dose by that concentration and multiply by 100 for U-100 units. This calculator does it from your dose presets.
What are the standard GLP-1 dose steps?
Semaglutide titrates 0.25, 0.5, 1.0, 1.7, then 2.4 mg weekly. Tirzepatide titrates 2.5, 5, 7.5, 10, 12.5, then 15 mg weekly. The presets in this calculator match those ladders.
Does this replace a prescription?
No. It only converts a dose your prescriber has set into syringe units. Always follow your clinician's titration plan and product labelling.
