Beyond Raw Concept X | Clinically Dosed Pre-Workout Powder | Contains Caffeine, L-Citrulline, Creatine, and Beta-Alanine | Sweet & Tart | 20 Servings

Best pre workout hands down! I gave it 5 stars for performance, it maximized my focus & stamina like no other pre workout had before. I was able to complete highly difficult intense training sessions starting with a hour of incline on the treadmill totaling between 1200-1600 calories which varies depending on incline & speed followed by what seems like a never ending cycle of sets & reps (realistically around 2-3 hours) then another round of treadmill incline & even after that still had lots of energy. Concept X gives one of the best pumps as well. You do get the jitters bc of the amount of caffeine & I believe it's also time released so energy is as sustainable as can get. So like I said before it's 5 stars all day, but from my experience for the most part it doesn't mix too well I usually had to add more water than what it calls for I think it's 8-12oz but I fill the whole shaker & the flavor is mid to average at best so I usually use lemon or lime water to make it easier to ingest. But with that said I'd still choose concept x over any other pre workout bc it delivers the best performance every time guaranteed!
