Calculators
Every tool runs in your browser, shows its formula, and pre-renders a default table so it answers even without JavaScript. Modeled estimates for research and education; not dosing advice.
See levels over time
Model how weekly doses overlap and build, with published ladders preloaded.
-
Dose-level plotter
weekly mg + t½ gives mg-eq curve
One-compartment Bateman model with published ladder presets, weekly peaks and troughs, and CSV export.
Convert mg, mL and units
Vial arithmetic for U-100 syringes, from any vial strength and water volume.
-
mg to units
mg ÷ mg/mL × 100 gives units
A dose in mg as U-100 units, with the concentration, mL and doses per vial.
-
Reconstitution
vial mg ÷ water mL gives mg/mL
Concentration from vial mg and water mL, units on a U-100 syringe, and the water for a target mark.
- Pen-to-vial converter
pen mg + vial mg/mL gives units
Labeled pen doses for four brands, as units from any vial strength.
Plan a schedule
Week-by-week dates for published trial and label ladders.
-
Titration schedule
ladder + start date gives dated weeks
Published trial and label ladders as a dated, week-by-week table.
Supply and storage
Cost from your own prices, and discard-by dates from label in-use periods.
-
Cost
mg/week × weeks + price gives vials, cost
Total mg for a schedule or published ladder, whole and fractional vials, and cost per mg from your price.
-
Storage dates
start date + days gives discard-by
Discard-by date and days left from label in-use periods, or from a period you enter.
