Can E go off?

Im buying some E in a week's time, and I'm not using it until new year's eve. I was wondered if a pill can lose it's potency if not stored properly for several weeks in extreme heat. It's Summer in Australia right now.
If anyone can tell me about how long E will last in storage and the best ways to store E I'll be very thankful.
Cheers

 

You have nothing to worry about..... e wont go off for ages. i heard a couple of years.

 

Smashing!

 

just dont leave it in direct sun or something u know

 

Yeah just store it properly, at room temperature and away from sunlight. Just treat it like you would any other pills.

 

i heard it can last as long as five years...
