Synthesis Institute
The relaunched pioneer of Dutch truffle retreats

About
Synthesis was one of the first names in legal psychedelic retreats; the original Dutch entity went bankrupt in March 2023, and the Immersion retreat program was relaunched in 2024 under new ownership with several original team members back. Five-day retreats at New Eden in Hemrik combine psychedelic education, workshops, breathwork, guided truffle ceremonies, and integration work, with 2026 cohorts bookable. Worth knowing the history; worth knowing it's running again.
