It's very plain and obvious that the arm-chair attacks are from people who just don't want you to help. Paid FDA or people who just love to argue. The point obvious is that good quality and effective and safe colloidals can be made by individuals. I smell that the strategy of the attackers may go far beyond real concerns. How much time do these attackers spend attacking the pharmaceutical industry? Answer = none. The purpose of their attacks is to confuse and scare away any readers and aggravate you. They are a scam.
