I am a big fan of the combination of Dynamine™, TeaCrine®, and Caffeine, and 8 PRE WORKOUT appears to have nailed the right combination and ratio of these ingredients. Maybe it’s the inclusion of AlphaSize®. Whatever the case, 8 PRE WORKOUT did precisely what a pre-workout is expected to do. However, I have one word of caution: if you are new to pre-workout formulas, you will want to start with one scoop to evaluate your tolerance. Otherwise, at two scoops, you might get overwhelmed. Determine how much you can handle and increase your dose in small ¼ serving increments.
