SURMOUNT-1 landed around 20.9% mean weight loss at 15mg over 72 weeks, against roughly 15% for semaglutide 2.4mg in STEP 1.

This is where I part company with the consensus forming above. The "tirzepatide is simply better" summary irritates me. It is better on mean weight loss, and the cardiovascular outcome evidence is far thinner than semaglutide's. If the reason for treating is cardiovascular risk rather than weight, the evidence base points the other way.

The figures, for anyone assembling their own picture. One habit that pays for itself: post the method alongside the number. A figure without its method cannot be checked, and an unchecked figure is how this community accumulates folklore.

Coming at Dr.NateNeph’s question from a different direction. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

One thing that is still open after Dr.EndoIndy’s answer:

Whether anyone has held 10mg long term rather than climbing, and what happened over the following year?

Closing the loop on my own question.

I stayed at 10mg. Another six months, another 7kg, no new side effects, and my reading of the dose-response says the last two steps were never going to be worth what they cost me.
