Transition timeline
Plan на 2-week prep + 12-week evaluation window. Most weight-loss outcomes can be re-assessed at the 12-week mark на the new medication.

Week −1: Last Compounded semaglutide dose

Week 0: First Ozempic dose
Start Ozempic at your equivalent dose (see table below). Combined effect may be elevated в the first week as Compounded semaglutide clears.
Weeks 1-4: Stabilization
Side-effect profile shifts. Adjust to new effect onset timing. Track weight + appetite.
Weeks 4-12: Re-evaluation

Beyond 12 weeks
If outcomes good, continue. If switch underperformed Compounded semaglutide, discuss reverting or trying a third option (often tirzepatide-based).
