clen shelf life.

Im curious to know what clen's shelf life is. I got some clen awhile back from LR.... after all the shit went down with them they sent me out some stuff because i had a backorder around that time, so i got a shit load for nothing. anyway. like i said i was curious if it's still good or if it would be bad by now (it doesn;t taste quite the same, but some cilias he sent out is still good lol). I've kept it in a cool place out of sunlight and extreme heat so maybe it's still good. i guess if it's shit now no loss since i got it for free. let me know fellas, i kinda wanna start up on it again before my next cycle...
thanks bros
