The mechanism is more central than most summaries suggest.

Pushing back on CarlaRPh_TPA here. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.

Adding the numbers, since they settle part of this. Numbers worth memorising for this class: Tmax one to three days for the weekly peptides, terminal half-life about a week for semaglutide and about five days for tirzepatide, steady state at four to five half-lives, subcutaneous bioavailability high enough that site choice is irrelevant.

Adding the part of the answer the thread has not reached. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

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

Which effects tachyphylax and which persist, because the answer explains why tolerability improves while the appetite effect keeps working?

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

Closing this out: the trough rather than the peak explains the pattern I was seeing on day six, which I had been blaming on the vial.
