Well, I was given a bottle of Pro Xanthine 500xt to try by my other half Onlychevy6 (Jeff). I will be taking only 1 cap per day until I'm told to take another one. I'm hoping to get similar result as Jeff. I know it won't be from lack of exercise cause he will work me like a "dog" in the gym. As far as diet, I will not change that since I have been seeing results! Most of my training to date has been all natural. I have tried a different fat burner months ago but stopped taking it after a few days. This time I will stick to it and use the entire bottle. My current weight as of this morning 166 lbs and my goal weight is 140 lbs right now however, that can change since I am a woman and entitled to change my mind at any given time!!
