Does TrackPep give Tirzepatide dosing advice?

No, and it never will. TrackPep is a record-keeping and education tool: you enter what you were prescribed, and it keeps the log, the maths, and the reminders straight. Dosing decisions belong with your prescriber.

How do I track a tirzepatide dose escalation?

Log the new dose when it starts. Your history keeps the previous doses and their dates, so the escalation shows up as a timeline rather than a number you have to remember.

Tracking, done properly

Tirzepatide tracking, week by week

Tirzepatide protocols usually run for months and change dose several times along the way. TrackPep keeps the whole history in one record, with the vial maths built in.
