I've had some creatine sitting around for about a year and it was previously opened. The expiration date is 4/04. How can I tell if it's still good? There isn't any clumping at all.

no clumping means it probably wasnt exposed to substantial moisture... it should be fine, try it out

As long as moisture does not get to it, your creatine should keep for a long time
