Orforglipron is the more interesting oral story because it is not a peptide at all.

I do not accept that the fasting window is a minor inconvenience. Adherence data on daily orals with timing requirements is consistently worse than weekly injections, and a drug you take imperfectly is a lower dose than the one on the box.

One concrete data point for the thread. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.

There is a second half to this that has not been said yet. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

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

How much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly?

Reporting back.

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.
