Steroid Plotter

Like the cycle plotter, this uses a one-compartment model with exponential elimination and dose superposition. The Y-axis is a relative level in arbitrary units — not ng/mL and not a clinical prediction.

Difference: each row has its own cycle length, so injections stop when that protocol ends while other compounds can continue — useful when stacking different on/off lengths. Ester or depot behavior is not auto-modeled; you enter half-life and an optional T-max ramp (0 = instant bolus after each dose event).

The total line is the sum of relative curves; it does not rank potency or true plasma exposure across drugs. Tune half-life and ramp from literature for each compound. Intramuscular PK is often multi-phase; treat this as an educational visualization.

Each compound has its own cycle length and injection schedule. The chart runs until the longest cycle ends plus five half-lives (washout).
