Steady state is faster than people expect: half-life about five days, so you are at plateau in roughly three to four weeks rather than five.

I read this differently from anders_CPH, on substance rather than tone. 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.

Adding the numbers, since they settle part of this. 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.

There is a second half to this that has not been said yet. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.

A narrower follow-up, since the general answer is now clear:

How much of the tirzepatide advantage is the GIP component and how much is simply that the dose ladder goes higher in receptor-occupancy terms?

OP back with an update, since a thread like this is useless without one.

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.
