I moved from brand to compounded semaglutide at the same nominal dose and cannot decide whether what changed is the material, my titration, or my expectations.
So the question, as narrowly as I can put it: how much of the between-person variation is pharmacokinetic and how much is just adherence measured badly.
Not looking for reassurance. Looking for the part I have got wrong.
This one has a reasonably settled answer, so here it is. Albumin binding above 99% is the whole reason weekly dosing works, and it is also why the trough matters more than the peak. People who dose late are not losing a peak, they are letting the trough fall, and the appetite effect tracks the trough.
Happy to go further on any of that.

Agreeing with PharmacoVig_BOS, and the qualification matters more than the agreement. 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".

That holds for the injectable. The oral formulation has different absorption behaviour and the dose numbers are not interchangeable, which is worth saying out loud because people quote them as if they were.
From the other side of the consultation, briefly.
LeilaHI said:...but the FDA says semaglutide...
Interesting point. I want to add some regulatory nuance: the FDA labeling reflects the specific clinical trial data submitted for approval. Real-world clinical practice often extends beyond the FDA label based on emerging evidence and clinical judgment.
Example: semaglutide was first approved for diabetes (Ozempic), then obesity (Wegovy). The molecule didn't change — our understanding of its applications expanded. Similarly, semaglutide may evolve as more data accumulates.
