This place sells the HCG diet. I did their 60 day program and if followed exactly it does work. I lost 41 pounds in 6 weeks. The down side is the cost, it was 400 bucks. They give you the HCG spray, an appetite suppressant, and B-12 drops.You go in every two weeks and weigh in and ask their advice for what you got going on. If you do this diet be very careful when you get off, it is very easy to gain weight back. Make sure you exercise and just don't go back to your old ways. It can be done cheaper see my other review on GNC read more
