Steroid Cycle Plotter & Visualizer

This tool maps your cycle inputs onto a single chart using a one-compartment model with exponential elimination and dose superposition (each injection adds a decaying contribution). The Y-axis is a relative level, in arbitrary units — not mg/day, not ng/mL, and not a clinical prediction.

Enter dose per shot, injection interval, elimination half-life in days, and optionally a short "T-max ramp" to approximate absorption from depot injections. Summing several compounds shows the arithmetic total of those relative curves; it does not compare potency or real plasma levels across drugs.

Adjust compounds and cycle length below — the chart updates immediately. Real intramuscular pharmacokinetics are often multi-phase; treat this as an educational visualization and tune half-life and ramp from literature for your compound.

Estimated relative level vs time

One-compartment decay model (superposition). Units are relative — not blood concentration.

Note: All calculations are estimations based on mathematical half-life modeling. Individual physiology varies and results may not reflect real biological response.
