My husband has done so much research it would blow your mind (!!!) on workouts, supplements, protein, and pre-workouts. This past Tuesday his order came in and we played Mad Scientist and mixed up our own pre-workout supplement. This stuff is amazing!!! I will have to look at his print out and see what all is in it but if you need something that is going to give you energy, give you focus, and help you beast out a workout, this is it!! I look forward to it!! Pre-workouts can be whatever you want them to be but wow, this is probably the best that I have had. I know, I know, you’re thinking “well, yeah, your husband made it of course you’d love it” but I don’t even mean it like that, it really is the best pre-workout that I have had to date!!
