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.
What I am trying to establish is how much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly.
Numbers rather than impressions, if you have them.
Answering the narrow version, because the broad one does not have a single answer. 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.
Correct me if the detail matters more than I have assumed.

No disagreement with LipidDoc_ATL. One condition attached. Worth adding that the tablet is taken daily, so a missed dose costs far less than a missed weekly injection. That is a genuine advantage nobody lists.

Can confirm the pattern MounjBrad describes. 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.
Adding the clinical framing, because it changes how the question reads. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.
