Frequently Asked Questions

How does the dosing schedule calculator work?

It converts your chosen frequency into an average number of days between doses, then multiplies that by your total dose count to estimate how long the vial will last and when upcoming doses would fall.

Why is 'every other day' or '3x per week' shown as a decimal interval?

Frequencies that don't divide evenly into 7 days produce an average interval, such as 2.33 days for 3x per week, so the projected calendar dates are estimates rather than a fixed weekly pattern.

Is this a treatment plan?

No. This is an educational math and calendar tool only. Always consult a qualified healthcare professional before starting or changing any protocol.
