TL;DR: Spreadsheets and single-purpose “steroid cycle plotter/calculator” tools can draw a steroid graph—but they won’t keep your data organized, connect to lab trends, or protect your privacy. CycleVitals brings a steroid cycle planner, steroid half-life calculator, injection scheduler, interaction checks, and AI-assisted lab insights together in one secure web app - free to start.

Convert mg, mL, IU, and more with concentration-aware math. CycleVitals’ steroid calculator handles mg/mL, IU/mg, IU/mL—educational use only.

Select two or more compounds and get a risk score, why it’s risky (mechanisms), when it’s riskiest (half‑life overlap windows), and what to do about it (monitoring and safer alternatives). Built for adults who want to reduce harm, not roll the dice.
