Only tried it once so far and it had great focus and energy through my whole workout.
A very good pre! One you should use on your highstim days,deliver the goods! High energy nice euforia,no crazy heart rate,you feel that the company uses high grade ingridients.and respects yoy as an athlete that like to go wild on his gym session. Highly recomended.( I have more then 15 orher pre's on any given day and I dont recommend frequently).
