I actually started monday, with 4 pills a day. Started a new job the past month and it seems to be consuming my life so ive been hitting the gym twice a week full body workout style. Today was day 4 and i dosed 3 pills pre workout, and 1 post. Then one later. Havnt noticed anything yet so im assuming it will take a little bit to get started. I have 2 bottles so ill be runnin 2 months total.
