In addition to having a 5-out-of-5 formulation, this is also one of the best-tasting pre-workouts we’ve tested and contains a moderate dose of caffeine that shouldn’t cause excessive jitters.

I’m not sure you’ll find a better pre-workout in terms of “bang for your buck”, especially when considering the ingredients.

But I absolutely love this supplement. I know it's super fun. Going to the store, know you're going to go do a a great bodybuilding full body workout, a chest, tricep, shoulder day, and you stop off at the nutrition store, grab a brand new preworkout, and go ahead and try it out.

Overall, BULK by Transparent labs is some of the best pre workout money can buy. I just need to find the best flavor they have and it will be a 10/10. Like I said though, flavor isn't what Im chasing. However, it is nice to have!
