On 25mg oral, four months in, and my results are closer to the low-dose injectable arm than to the numbers being quoted for 50mg.
The practical numbers: about 1% oral bioavailability, 30 minutes fasted before food, no more than 120ml of plain water, and coffee counts as food for this purpose.
So the question, as narrowly as I can put it: whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong.
I have searched first, so if this is covered somewhere point me at it and I will read it.
Taking the question as asked, rather than the general version of it. Orforglipron is the more interesting oral story because it is not a peptide at all. Being a small molecule it does not need SNAC, does not need the fasting window, and has oral bioavailability in the tens of percent rather than about one.

No disagreement with NurseKim_ATL. One condition attached. The absorption variability is real, but it partly averages out over weeks — the steady-state trough is less erratic than any single day would suggest. Where it bites is in the first fortnight, when people conclude the tablet does nothing.

Same position here, arrived at the long way round. The OASIS programme put 50mg oral in the same territory as 2.4mg injectable — around 15% mean weight loss — but it needed a dose 20 times larger to get there because almost none of the tablet is absorbed. The dose numbers are not comparable across routes and quoting them side by side confuses people.
Clinical perspective, offered as context rather than as advice. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
