Review: On my first week with Dren I had some side-effects make me go to the bathroom after 30 min so I wait one - two hours to workout, and feel some jittery too, second week no side effects at all now I'm on my third week I sweat a lot during workout. I never use any stimulant before I don't drink coffee, no caffeine, I'm glad that the side effects stop after a week, I finished the box I'll burn without it to see the difference.
