I picked up a box of fizz fuel from the "super sale" bin at vitamin warehouse here in vegas, for $5. I have done this before and had no problem...however when i mix this particular pack in water it just doesnt fizz that much. or as much as normal.
anyone know if whatever makes effevescent creatine bubble can expire? it still tastes fine btw.
i also cant find any dates or anything on the box indicating that it would expire, just a lot #.
