Bob Beck seems so sincere and accurate but people using his protocol for hiv don't seem to be getting the results he claimed. Yes, ozone made from pure Oxygen is many times more potent than ozone made from ambient air. Ozone will kill microbes outright and not just stun them. Considering hiv resides mainly in the gut drinking heavily ozonated water may have good effect. Ozonated water that starts with Pure Oxygen to make the ozone is going to be many times stronger. There is a big difference when you use pure oxygen as you have stated. I wish I could test this theory further, but need to take the meds due to the very low T-cell count of 80. This could be the key to making the Beck protocol work for hiv. Additionally I would recommend the ankle-to-ankle method for zapping and use the zapper overnight. I would like to see this work consistently everytime against hiv for all users.
