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.

Pushing back on BethLabQueen here. 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.

I would rather be corrected than agreed with, if it comes to it.

The figures, for anyone assembling their own picture. A quick sanity check on any figure quoted here: is it mean or median, is it intention-to-treat or completers, and what was the comparator. Three questions, and they resolve most disagreements in these threads.

There is a second half to this that has not been said yet. The gap between trial results and real-world results is consistent and it is not fraud. Trial participants get titration by protocol, scheduled contact, free drug and dietetic support; removing that infrastructure costs a few percentage points every time it has been measured. When your own curve sits below the published mean, that is the likeliest explanation before anything about you or your material.

Following on from tony_orlando — and this may be the naive question:

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

Reporting back.

Reporting back after another eight months at the same dose. Still losing slowly, no new side effects, and no reason I can find to climb further.
