Don't buy it on Amazon!
Since I didn't open the package until I actually started using the supplement, I am way over the return period.  I can't return on amazon nor can I return through beach body.  This product gives me pins and needles sensation and my whole body is itchy right now at 3:30 pm. I took the recommended dosage at 6:00 am before my morning workout.  It really doesn't worth the energy boost that it gives for a half hour that I am suffering all day after.
