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

How long did you give it before you decided it was working?

I do not accept the framing. The question has been narrowed to the version that has a tidy answer, and the part that was dropped is the part the OP actually asked about.

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

No disagreement, though the timescale matters more than the mechanism here. Most of what looks like a difference in kind turns out to be a difference in how long somebody waited.

Worth separating that from retatrutide, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Bookmarking. The distinction being drawn above is the one nobody else makes. Taking it to my next appointment.

From the other side of the consultation, briefly. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.
