One concrete data point for the thread. For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.
Following on from NurseAsh_DET — and this may be the naive question:
Whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong?

Adding the part of the answer the thread has not reached. The dose-response is real but shallow at the top. Across STEP 1 and STEP 4 the gap between 1.7mg and 2.4mg is a couple of percentage points of body weight on average, and the average is carrying a wide spread — plenty of people at 1.7mg sit above the 2.4mg mean. If a dose is working and tolerable, "working" is the relevant variable, not "maximal".
Worth separating that from semaglutide, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Update — I went back to the injectable. Not because the tablet did not work, but because the fasting window and my mornings were never going to agree.

Agreeing with Dr.LeslieOBGYN, and the qualification matters more than the agreement. Worth adding that the tablet is taken daily, so a missed dose costs far less than a missed weekly injection. That is a genuine advantage nobody lists.
