Dr. Fassnacht studied blood tuning with Dr. Strunz personally and introduced blood tuning in Switzerland in 2016.
Since autumn 2022, Dr. Fassnacht has been working with Mr. Alexander Sahmel and supporting him at the Swiss Center for Health and Longevity, where he offers the best and most modern biohacking and longevity treatments.
Since November 2025 Dr. Fassnacht has closed his practice due to age-related reasons. He is only available for consultations and examinations.
