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 sits in the newer, more hybrid end of the psychedelic training field: part retreat operator, part practitioner education provider, with a strong emphasis on safety, screening, and experiential learning. It is best suited to people who want a research-informed, values-led introduction to ethical psychedelic facilitation, especially those drawn to psilocybin truffle work and small-group, reflective training rather than a conventional clinical diploma. Its lineage is notable for its long-running collaboration with Imperial College London and for building training from direct retreat experience, though it is still a private provider rather than a university.
Best for clinicians, wellness practitioners, spiritual caregivers, and serious aspiring facilitators who want a structured, interdisciplinary route into psychedelic practice. It also suits people seeking hands-on practicum and Colorado-facing facilitator preparation, provided they are comfortable with an intensive, non-university pathway.
Synthesis requires applicants to be 18 or older and to complete a safety and suitability screening. No prior psychedelic experience is required for the Immersion retreat, but the training and practicum are only open to qualified or admitted Core Training participants and graduates, and the practicum has its own admissions process.
The Psychedelic Practitioner Core Training is approved by Colorado's Department of Regulatory Agencies as a state-licensed training centre for psychedelic facilitators, and Synthesis says it meets and exceeds Colorado's 150-hour didactic training requirement. The programme leads to a certificate of completion, and the practicum leads to a Practicum Completion Certificate; the site does not present the training as a university degree or a CME/CE programme.
Core Training tuition is $11,497, with early-enrolment discounts and a 12-month payment plan available. The practicum is separate and costs between $2,500 and $2,900 depending on discounts and bundles; the Immersion Experience is also separate from Core Training tuition. Synthesis charges a $500 screening fee for retreat applicants, deducted from the retreat fee if they book.
Graduates walk away with a broad, interdisciplinary grounding in ethical psychedelic facilitation, from screening and preparation through holding space and integration. The pathway can also include practicum hours, professional continuity workshops, and Colorado-focused training components for those pursuing facilitator licensure.
