We all do! That's why A.C.T. was designed by laboratory chemists to work at the cellular level, which means it works fast! The special blend of amino acids, B-vitamins and Creatine is formulated to last long, too! The effects of A.C.T. typically last three to five hours.  And it's gentle when it wears off, with no excessive fatigue or crashing! Just mix with water or fruit juice, and enjoy. Share A.C.T. drinks with friends, and earn B-I-G rewards!
