Live math

Enter every value to see the calculation.

Calculation only. Prominent display values are rounded to at most 2 decimals for U-100 units and cost, and 3 decimals for mL; calculation-value lines retain up to 8 decimals. Math uses unrounded values throughout. PepRack does not recommend a dose, schedule, injection method, or treatment.

Calculator notes

What schedule does the chart show?

It shows eight instantaneous doses at the interval you enter and ends one interval after dose eight. Calendar time is omitted; only elapsed time is modeled.

Is this a blood-level prediction?

No. It is a simple mathematical decay model, not a pharmacokinetic or clinical prediction.

Where should the half-life come from?

Use a value from an authoritative source for the exact product or compound you are researching.
