Its probably fine. I had some old creatine that wasn't sealed, but it still appeared the same and was tasteless after 1-2 years. Provided it was stored in a cool, dry place I wouldn't worry too much.
i saw this fat bastard on tv recently. he has a girlfriend too. ironically, she seemed sorry for him and sympathetic as she bathed him, but then she goes and brings him back a 4000 calorie snack with a gallon of ice cream. go figure.
