Almost 2 month old SN in backpack

[Iwouldratherdie]

I've kept my SN in the container I got it in then inside a glass cup in my backpack which i bring almost everywhere. Ive been in warm temperatures since its the summer. ive opened the plastic wrap But the cap is on. Is my SN still okay?

I'm inclined to say it should be O.K.
It really takes quite extreme heat to completely degrade SN,but that's not to say prolonged heat exposure can't cause it to degrade somewhat overtime.
The storage instructions are available for good reason.
If you're still in doubt,you could test it with an aquarium test kit,which you may be going to do anyway.
