Half-life & saturation plotter
Set a compound’s dose, how often you take it, the cycle length, and its half-life to see the blood level build toward its steady-state plateau, then clear after the cycle ends. Add more compounds to compare several on one chart.
This is not syringe units. The dose below is the actual amount of compound, in micrograms (mcg) or milligrams (mg). If you only know your dose as units on the syringe, use the reconstitution calculator to convert units to mcg or mg first.
