Formulated by former Yale Research Scientist, Dr. Jim Stoppani.


The pre-workout has ended up being the weightlifting team’s favorite pre-workout of potentially all time and that’s coming from people who have used more than 50 pre-workouts. For the last few months, this is the one they grab most often and enjoy the most, both in taste and in effects.
I've used a few different names in my fitness journey, and JYM has given me the cleanest, most effective PRE I've experienced. I'll be hard pressed to switch to something else at this point. The flavors are awesome, which is a huge plus!
The Pre JYM is my favorite. I have tried a lot of other ones but these are by far the best ones. Great focus, helps get a good sweat going and works long after the workout is over.
