Half-Life Plotter

This tool plots what a half-life actually means: a single dose decaying, and a repeated-dose schedule accumulating toward steady state. Change the half-life and interval and watch the curve — this is the math behind "why weekly" and "why titrate."

Dose (arbitrary units)

Dose interval (hours)

What this tool is for
