weight loss
"I'm 17 and a 4 sport athlete. I'm 6' and weighed 200 pounds but didn't look a pound over 160. I got prescribed for Phentermine when my weight started to yo-yo drastically, and got down to 170 in a month without becoming sickly skinny. 
Although this pill hypes me up and makes it harder to fall asleep at night, I combined OxyLite with it to burn even more calories. NOT a good idea.
Now, I have stopped taking Phentermine and my weight is up to 190, though I still exercise exactly the same amount."
