Plateau breaking story with a stall: I stalled at 198 lbs for 7 weeks.

That is correct as far as it goes, and here is where it stops going. Most reported plateaus are not plateaus. Weight is a noisy signal — daily variation of one to two kilograms from glycogen, sodium and gut contents — so a fortnight of flat readings is well inside the noise band. Before concluding anything, look at a rolling weekly average over at least four weeks and at a tape measure, because recomposition shows up in circumference before it shows up in weight. Then track intake honestly for a week: appetite suppression fades unevenly, and intake creeping back up is the single commonest cause.

Thirteen weeks at the same dose with no change on the scale, and I have gone from assuming it was the drug to assuming it was me and back several…

Adding a me-too, because a thread of one person's experience is not much use. The detail I would add is minor and it is already implied above.

Adding the clinical framing, because it changes how the question reads. Whatever the answer turns out to be, the method for getting there is the same: state the assumption, do the arithmetic in public, and invite the correction. That is slower than asserting, and it is the only version that survives being wrong.
