I used it last year about this time and had to stop because of the bad detox symtoms , they wanted me to start out at 15 sprays per day and only started out at one spray just to see how I would do on it ,about three days into it stated to get the detox symtoms , this was before I had my amalgams removed , also it contains stuff that cutler warns against in his book , like chlorella and yes it is very expensive , I paid about 100 dollars a bottle which if used according to them will last about one month , and after I told them about my reaction and how low a dose I was using they said to stop using it , I asked what there refund policy was they said that most online retailers will not do any refunds on there product
