How long can we store P2NP?

[nofuckups]

Let's say I refrigerate 99% pure p2np in an airtight container. How long can I expect it to last without degradation?

It came in a sealed Al bag and I haven't opened it yet. What's your practical experience with storing p2np at normal refrigerator temp?

It can be stored in the freezer for years, nothing will happen to it.

You can do recrystallization to refresh the substance after long storage
