Room temperature Mounjaro box

From what the instructions say, the one-time pens and containers stay okay away from cold storage as long as it doesn't exceed thirty degrees for twenty-one days altogether. The version with multiple uses lasts thirty days without refrigeration. Store them inside their packaging and out of sunlight, and throw them away after the period ends, no matter if you cool them again later. In my area summer heat often passes that mark, which is why I prefer a shaded drawer over the counter.

Realistically it stays safe and effective for much longer than the official numbers. I keep using mine until it's gone. I have an open vial of semaglutide that's been in my fridge for over a year and it still works without making me sick.

What about homemade pens? Suppose I make 5 of them and put them straight into the fridge. How long would they stay fine?

I've seen mentions of testing done on this, though I haven't found the actual public data. From what I gather the compound holds up very well. It even survives freezing, which says something about its stability.
