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 LarryQC_SD, 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.

The figures, for anyone assembling their own picture. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

Correct me if the detail matters more than I have assumed.

There is a second half to this that has not been said yet. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

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?

Reporting back.

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.
