GLP-1 dosing calculator
You are trying to work out how much to draw or when to step up.
Reference and calculator, not medical advice. This page explains how something works; it does not tell you what to take. Last reviewed August 2026.
Converting a GLP-1 dose to syringe units is one calculation: divide the dose in milligrams by the vial concentration in mg/mL, then multiply by 100. The result only holds for the concentration printed on your own vial — the same milligram dose lands on a completely different mark at a different concentration.
mg → syringe units converter
U-100 syringe. Formula: (dose ÷ concentration) × 100.
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.
Every product above holds each step before the next increase, and that spacing is the whole design — it is what keeps gastrointestinal effects manageable while the dose climbs. Which product and which step suit you is a prescribing decision, not a comparison you can finish here.
Sources and last review
This page is general reference rather than a dosing table, so it quotes no figures from a label. Nothing here is reviewed by a clinician, and this site does not employ one — which is exactly why what I do publish stays traceable to its source.
- This page carries no product-specific dosing figures. The labels behind everything on this site are listed on the sources page, and the originals live on DailyMed.
