PSA for titration users considering the 0.25mg starting dose: this dose is NOT intended for weight loss. It's a titration dose to let your body adjust. Don't be discouraged if you don't lose much in the first month.

The therapeutic dose for weight management starts at 1.7mg (semaglutide) or 5mg (tirzepatide). Be patient with the ramp-up.

One thing that is still open after TinaHashiRN’s answer:

Why the interval is four weeks rather than two, and whether a slower ladder gets to the same place?

Dose escalation anxiety for titration: I was terrified to move from 0.5mg to 1.0mg based on horror stories in this forum. But my actual experience? Slightly more appetite suppression, zero additional side effects.

Remember that the people posting about terrible side effects are a biased sample. Most people titrate up without drama — they just don't post about it because it's uneventful.

Closing the loop on my own question.

Closing this out: I held the step for six weeks rather than four and it settled without a dose change. The interval was the answer, not the dose.

That is right for the weekly injectables. For the daily agents the interval logic is different and the four-week convention does not transfer.
