It really didn't work for me at all. I felt absolutely no change after two full bottles. When I went to claim my 100% money back guarantee, they said they had a lot of re-stocking fees, etc. I spent $294, and they refunded me $44. STAY AWAY FROM THIS PRODUCT! Just because they have Oprah shilling for them, doesn't mean its a good product. I got sucked in (and sucker punched).
