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.
What would genuinely help is knowing whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong.
Practical detail welcome, however dull — the duller the better.
Short answer first, then the reasoning. 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.

No disagreement with Dr.RenalNash. 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.

Can confirm the pattern patPC_UT describes. Oral semaglutide is absorbed in the stomach with the help of SNAC, which locally raises pH and protects the peptide long enough to cross. That mechanism is fragile: bioavailability is roughly 1% and highly sensitive to gastric contents, so a mouthful of coffee genuinely changes the exposure. This is why the label wants 30 minutes and no more than half a glass of plain water.
If somebody has the primary source to hand I would rather cite it than paraphrase it.
