WWB semaglutide stability test — what worked for you?

That holds for the injectable. The oral formulation has different absorption behaviour and the dose numbers are not interchangeable, which is worth saying out loud because people quote them as if they were.

Worth separating that from storage and cold chain, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

The mechanism that matters here is not stomach emptying, it is central.

This answered a question I did not know how to ask. Sending this to two other people who asked me the same thing last week.

Pushing back on NurseLeah_Nash here. The trial means are being read too generously in this thread. STEP populations were selected, supported, and titrated by protocol, and the real-world curves are consistently a few points worse. That difference is not noise, it is what happens when you remove the study infrastructure.

The figures, for anyone assembling their own picture. Practical: unopened, refrigerated at 2 to 8°C; in use, refrigerated and used within the preservative-limited window; never frozen; and a visual check every time — a haze that does not settle is a reason to stop, not to wonder.

That is the short version; the long version is somebody else's post.
