storage and lifespan on these products

What up, Im Thai and I wanted to ask a couple of questions.

Firstly, If properly stored, What is the lifespan of these products?

Secondly, What does “properly stored” entail?

I live in an area that would facilitate good storage, but find myself traveling to Arizona and places where it is quite a bit hotter. SO that being said, will any of these products degrade in heat above lets say 100 degrees? Im looking at some A314, TUTH, AMMO, IS, IO, and SPACELAND. I would think not, but you never know.

Thanks,

THAI
