hey scott...
well, all i can say is that i have only been taking xenadrine for one week and am only taking one pill a day in the morning....i am choosing to take it slow because the one pill lasts about 8 hours for me right now...i think next week i will start to take an additional one in the afternoon. this week i have lost about 5 pounds....i do go to the gym 4 days a week and do weight training for an hour...i don't like to take it before i work out because my heart rate goes way to high so i work out first and then take it after.
hope this helps a bit.....good luck!!
