Fastin
"I took this and it's the best thing I have ever tried. The first couple of days I went by the directions then I doubled the dose. And I lost 20 pounds in 2 weeks.  It did make me feel very jittery and my heart rate was going 90 to nothing but I was determined to lose weight.! And a little information DO NOT I repeat ( DO NOT ) take Fastin before you get in a tanning bed. Tan first then take it. It made me very very strange in a bad way.  I'm no doctor but when I increased my dose I had the shaking and the increased heart rate. But It never harmed me."
