Course Provider
Synthesis is a legal psilocybin retreat company based in the Netherlands, offering 'Immersion' — a comprehensive 7-week program including a 5-day in-person psilocybin truffle ceremony retreat held at the New Eden venue 90 minutes from Amsterdam. Founded in 2018 and having supported over 1,100 individuals, Synthesis integrates modern science with contemplative wisdom traditions and has collaborated with the Psychedelic Research Group at Imperial College London.
Synthesis looks like a polished, commercially scaled psilocybin retreat and practitioner-training outfit rather than a purely therapeutic clinic. Its strongest lineage is probably the blend of retreat craft, self-exploration and research-facing legitimacy, especially the long collaboration with Imperial College London and its Colorado-facing facilitator training pathway. It is likely best for people who want an experiential, legally structured, high-touch introduction to psychedelic facilitation or a supervised retreat in a controlled setting, rather than for those seeking a narrow clinical or university-style course.
Best suited to curious adults, aspiring facilitators and practitioner-minded people who want a highly experiential programme rooted in legal psilocybin truffle retreats. It seems less suited to people looking for a formal clinical qualification or a low-cost introductory course.
For the Psychedelic Practitioner Core Training, no health screening is required for acceptance, but a separate Health Screening Questionnaire is required before the Immersion Retreat. No prior psychedelic experience is required for the Immersion Experience, though eligible attendees must pass health screening to consume psilocybin truffles. Some practicum sites may have their own experience requirements.
Synthesis states that its Psychedelic Practitioner Core Training has been approved by Colorado’s Department of Regulatory Agencies as a state-licensed training centre for psychedelic facilitators, and that the training meets and exceeds Colorado’s 150 hours of didactic training requirement. It also says graduates still need the Practicum, Consultation and Colorado Module for licensure. I found no clear claim of CME or CE credit in the sources reviewed.
The Psychedelic Practitioner Core Training tuition is $11,497. The Immersion Experience starts at $4,900, varies by discounts, room choice and venue costs, and does not include travel or transport. A $500 screening fee is charged upfront for retreat applicants and is deducted from the retreat fee at booking; Practicum tuition ranges from $2,500 to $2,900, with possible bundle discounts.
Graduates say they gain a broad, interdisciplinary grounding in safe and ethical psychedelic facilitation from screening through integration, plus peer networks and practicum access. The training is positioned as a route into supervised roles in clinical trials or other psychedelic organisations, and, for the Colorado pathway, a component of preparation for facilitator licensure. The Practicum adds supervised field experience and a Practicum Completion Certificate.
