I personally use the AdvoCare products. They are safe and provide an exceptional advantage both with intense training and on game days. The Active products will not give you what you do not have in competition, but they will extend your performance level sustainment beyond what you would normally experience for fatigue. Active products also enhance your energy level to reach and sustain your highest potential during performance. No more failing to reach your maximum. The products power you through your normal fatigue factor and beyond.
Products that I find particularly beneficial are:
Pre-workout: Catalyst, O2-Gold, Muscle Fuel, Spark, and Slam.
Post workout: Rehydrate, Workout Recovery, and Nighttime Recovery.
