Review on 💪 Bull Blood Ultimate Pre Workout: Maximize Energy, Focus & Blood Flow with Nitric Oxide, Creatine, and Lion's Mane - Unisex Power Preworkout Supplement - Enhance Muscle Size Naturally - 30 Servings by Doris Tran

I used to use a lot of pre-workout powders. I have to say that while BB is a decent product, I noticed something after a few weeks of use. Taking it gives you a quick burst of energy that builds for about 1-2 hours, then a HEAVY crash occurs. And I mean hard enough that you want to go to sleep. In my opinion, other pre-workouts have somehow avoided these problems, but unfortunately not this one. Avoid this if you don't want to follow the pre-workout with other caffeine sources.
