I'm using Jack3d right now and it is nasty. tatses like crushed tylenols, its alright with gatoraid, but makes you feel like you drank a pot of coffee so go easy at first if try it. I'm going back to Muscle Pharm which tastes good and doesnt make you feel jittery. The only reason I tried Jack3d is because the store was out of MP and the lady said it tastes good

. Now I need to find a new store.
