Muscle Pharm fans have just been given a reason to shop at GNC. Not only is the new grape blast flavored Assault being stocked by the retail giant. They also have an exclusive 60 serving bottle in grape and fruit punch. The current sale on the regular sized pre-workout actually makes it the better deal for now. GNC do usually charge quite a bit more than the rest so if the $80 price tag is putting you off. Think of this as a collector’s item.
