This is just a FYI for anyone..... if you were looking for a supp that gives you incredible pumps, focus, and a burst of energy that helps drive you through your workouts......Get NO-EXPLODE! It is manufactured and dist. by BSN. Bulk has it for $40 and it contains about 40 workouts worth.......this S*^t had me jacked up....my arms were swollen after the first four sets and didn't calm down for about an hour after my workout.....my wife thought there was something wrong with me....she noticed as soon as she saw me.
