I like how Dr. Andreas Kalcker made videos easy to understand to anyone as this is out of my field. I've learned and confirmed knowlege obtained from Telegram groups regarding Chlorine Dioxide. The zoom meeting was especially helpful for clearing up some confusions I had. I only wish there are even more video courses. Thank Dr. Andreas Kalcker and all of the people making this happen.
