Dear Dr.Kalcker, I would like to take an opportunity to thank you for your shared knowledge and effort to help humanity. Such an incredible course! Over past 5 years I was reading and learning a lot about MMS but CDS seemed confusing till I took a course and made my first CDS! it's so much easier then I thought! Such a great presentation! Can't wait to learn more !

Tempted to do in German also 🙂 Super clear explanations, vital information in nice, appealing presentation. Thanks and BLESS YOU, Andreas and team

This masterclass was amazing! Event thought I have been attending master classes for a lot of natural health treatments and more over the years, I still learned very much. This is a must if you want to know how the body works and heals! It's not perfect, it often lack subtitles, and it's fast sometimes (I wish I could play 0,8x speed), since English is not my 1.th language, but it's still amazing!

Dr. Kalcker gives just enough technical information to make the concepts understandable, but not too much that would cause people to get lost. The course is both highly practical and inspiring. It is a great companion to his books. The blending of biophysics into the conversation about CD/CDS is very insightful and it makes it fun to explore new paradigms of health and healing.

Thank you Dr. Kalcker. I have been following your work for several years now, and I truly appreciate the dedication you bring to your field. I love your books and feel deeply grateful for this valuable educational material. Everything you presented is clear, structured, and easy to understand, which made the learning process both enjoyable and empowering.

Thanks to Dr. Kalcker and the entire team.

I am so appreciative of the wonderful teaching, excellent presentation and organization of the material and life changing information. I highly recommend this class to anyone interested in healing. Dr. Kalcker and his colleagues are change agents bringing invaluable teaching to the world. Thank you! Barbara Grinnell PhD

Molto interessante, utile e stimolante. Avrei gradito i sottotitoli, anche solo in inglese. Fornisce tutto il necessario per poter utilizzare il ClO2 in modo consapevole e corretto. Grazie

I have followed Andreas Kalcker since 2020, by reviewing many separate videos, trying to learn all I could about CDS. This course brought everything together in an easy to learn, comprehensive platform. I've helped a handful of people with CDS, since 2020, but now I will be able to help more and help them understand why CDS will work for them. The certification will provide me with credibility.
