Plan cycles with a stronger harm-reduction lens.

The steroid planner focuses on simulation, dose timing, and recovery considerations to support more informed harm-reduction decisions.

  • Model dosing schedules and cycle structure more deliberately.
  • Review planning variables before making protocol changes.
  • Use a harm-reduction framework instead of ad hoc trial and error.
