Decided to try adrenal formula from dr christopher. It suppose to give me more energy, but instead it made me sick. During the time I used this it gave me severe side effects including shaking, trembling etc. I tried to contact David Christopher asking for advice, but he never answered the phone, neither any emails. I know of other horror stories from people who tried his other products. How can he possibly claim to have the answer for this many diseases?? (including diabetes) Its is criminal in my opinion. The guy does have obviously one single objective, which is called 'profit'. So..another scam, horrible product, wish I would have never taken it.
