GLP-1 Titration Calculator

Pick a GLP-1 compound and your vial setup, and this tool converts the published week-by-week escalation steps into the exact draw for each phase — volume and U-100 syringe units. It is a measurement reference, not a prescription.

PepDose Research·Reviewed Jul 2026

Quick summary

Converts published Semaglutide, Tirzepatide, and Retatrutide escalation steps into syringe units for your vial.
Set your vial mg and bacteriostatic water; every step recalculates instantly. On a U-100 syringe, 1 mL = 100 units.
Reference and conversion only — not a dosing recommendation and not medical advice.

How to use it

Choose your compound, then set the vial size and bacteriostatic water you used. The concentration (vial ÷ water) determines the units for every escalation step. Change the water volume to move the whole schedule onto cleaner unit marks.

Reference only. The step amounts reflect commonly published escalation timelines and are shown for unit conversion, not as a recommendation. Nothing here is medical advice.

GLP-1 titration FAQ

What does this GLP-1 titration calculator do?

It takes a published escalation schedule for Semaglutide, Tirzepatide, or Retatrutide and converts each step into the exact draw — volume and U-100 syringe units — for your specific vial size and water volume. It is a unit-conversion tool, not a prescription.

Where do the schedule steps come from?

The step amounts reflect commonly published clinical-trial and label escalation timelines for each compound. They are shown for reference and conversion only, not as a recommendation for any individual.

Is this medical advice?

No. This is a research-planning and measurement tool. It does not recommend that you take anything, and it does not replace guidance from a qualified professional. Compounds referenced are sold strictly as research chemicals.

How do I keep every step on clean units?

Your water volume sets the concentration, which sets the units for every step. If the steps land on awkward fractions, adjust the water volume — the reconstitution calculator's reverse mode can help.
