Bio Spira storage

I've heard mixed opinions on this topic. It's says right on the bottle that no refrigeration necessary. It will be 5 weeks until my tank arrives which will use two bottles. I have two more for later on.

Fridge or not?

I noticed petsmart doesn't put it in the fridge for whatever that is worth.

I'm a little skeptical on the bacteria in a bottle. I hear good thing about biospria though.
