How should I budget for a Karl Fischer water content test across a twelve-month oral semaglutide course?

The particulars: a Karl Fischer water content test · oral semaglutide.

I want to decide this in advance so that I am not deciding it under pressure later.

Assume I will follow the plan I write down, so I would like it to be a good one.

What should I decide now, and what should I defer?
