Freezing is the one to avoid, and freeze-thaw more so.

Storage question about storage and cold: my pen was left out of the fridge for 8 hours. Is it still good?

Per the manufacturer, both Ozempic and Wegovy pens can be stored at room temp (up to 86°F) for up to 28 days after first use. So yes, it should be fine as long as it wasn't exposed to extreme heat.

A narrower follow-up, since the general answer is now clear:

What would you measure differently if you were starting again?

There is a second half to this that has not been said yet. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.

OP back with an update, since a thread like this is useless without one.

Follow-up — I binned the frozen one. Aggregation does not undo itself and I was not going to inject a maybe.

Correct as far as it goes. The part it does not cover is what to do when the honest answer is "not enough data", which is more often than anyone likes.
