Thought the first Jack3d was Okay, Didn't like how it didn't have any pump ingredients which this one does.. From first glimpse at this label I thought it would be a bit average but on trial I actually thought it was quite grunty and made me feel pretty good and noticed it made me start sweating within five minutes so i'd say it's also quite thermogenic.. However the main thing I'm after at the moment in a pre-workout is a good clean strong stimulant which lasts me through my workout without a crash and I think Jack3d is pretty dam good.
