What reviewers didn't like

Has artificial colors, flavors, and sweeteners
May induce jitters if you aren’t used to drinking much caffeine
Has a lot of caffeine even for a pre workout, so it’s good for people who can really pump out sets in long workouts. Also should be taken earlier in the day for this reason.
- Heavy
Takes a few days for the body to adjust to this product
It was also a shame that it doesn’t use Taurine, which is a popular ingredient in commercially-available energy drinks.
