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.
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 question I want answered is how much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly.
I have searched first, so if this is covered somewhere point me at it and I will read it.

Dr.NateNeph has the substance of this right. The condition it depends on is worth stating. 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 mike_nyc 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.
Happy to go further on any of that.
