I have never been advised so comprehensively by a doctor, both medically and as a person, as by Christina Zech and her Coretify team. I really understood why I needed to change something in my life. From then on, it was easy for me to implement the changes. And the result is great: I stopped taking L-thyroxine after 3 months of Immunmaster and my latest labo values are still almost in the normal range. I had hoped for that, but not really expected it. Now I am looking forward to even more successes.
