You are obsessed wtih GNC, as if there were no products out there better than theirs.
Just as I was supposedly obsessed with whey protein, even though listed at least three products that were either blended proteins or from a non-whey source altogether.
Plus, GNC doesn't make Size-On; Gaspari Nutrition does.
GNC is a great place to get supplements, particularly when they mark their items down for clearance. A prime example would be what I've just picked up yesterday, a 10-lb bucket of Muscle Juice 2544 for $18 and change.
If you can post some places that give better bargains, be my guest.
