Explosion is prob, stronger than Jacked 3d (IMO) or 1 MR... I have been doing my explosion mixed with BCAA n More as my pre workout/ during drink mix for workouts...The one thing I like about Explosion is that Sarah can use it without upsetting her stomach...The 1 MR, amped her up, but really upset her stomach...Using 1 scp. of Explosion, and she is ready to hit the treadmill running..LOL !!!
