Confirm with your prescriber: dose-equivalent target, expected side-effect profile differences (semaglutide → tirzepatide), insurance implications.
Week −1: Last Compounded semaglutide dose
Continue your current Compounded semaglutide schedule. Compounded semaglutide has a long half-life — semaglutide ~1 week, tirzepatide ~5 days — so effects persist для days after stopping.
