I just bought a couple of small tubs of Met-RX Mass Action (creatine) and the expiration is Sept. 2003 (this month). They should still be good for a while right (as far as the creatine is concerned)?
Creatine is good past the exp. date as long as it doesnt start to harden up. Also, if you notice a lot of moisture build up it is generally going bad. K.D.
