Review on Pro-Series Muscle Builder - High-Quality Energy Supplement for Muscle Building and Mass Gain - Enhance Muscle Growth, Optimize Post-Workout Recovery, and Increase Pre-Workout Strength - 60 Servings, Grape Flavor by Christina Smith

I buy supplements not for claims of performance but for the price of ingredients that I know work. I took a chance because Revain had a great deal and I was very surprised when I first used it as a mix during a workout and just didn't get the usual fatigue after a few hard sets. It was like a fast-acting creatine blend that allowed me to add a few reps and a few more sets to each workout. I have a few other pre/post workout blends that I really like and will continue to use, but this stuff is definitely a good choice. The taste is definitely weird, and there's a roughness to the mix itself. Not enough to bother me, but very noticeable.
