The most extreme competitors believe in all or nothing, go big or go home. For extreme competitors, average is not enough. There will always be a boundary to break, a limit to push, a goal to demolish, and more to achieve.

After extensive research we developed C4 Extreme Energy™, a pre-workout supplement that matches the competitor's extreme passion, drive and commitment to succeed.

 Directions for C4 Extreme Energy

DO NOT EXCEED RECOMMENDED DAILY INTAKE. USE ONLY AS DIRECTED. Take one serving (1 scoop) of Cellucor C4 50X, mixed with 4-6 fl. oz of water 20-30 minutes before training. Once tolerance has been assessed and you are looking for an additional boost of energy, take one additional serving (1 scoop) with serving taken before training. DO NOT EXCEED 2 SCOOPS PER DAY. During your workout, it is recommended that you drink plenty of water or performance beverage such as Cellucor Alpha Amino to stay hydrated. Some individuals may experience a harmless tingling sensation, which is attributed to beta alanine.
