storing protein powder long-term

[ridethesnake]

So I'm one of those wierdo survival minded people.

I'm building up a food store. I'd really like to include protein powder and I figure since there are some really educated folks around here that maybe someone would know a little sum'n sum'n.

Does anyone know how long it stays good for?
Are certain proteins longer lasting?
How would you recommend storing it?

Thanks a lot.

there is usually an expiration date on the tub/package.
