Contributing to Science

Synthesis is committed to science-based data and contributing to research. To date we’ve collaborated with The Psychedelic Research Group of Imperial College London in a pilot study where it was revealed that the largest contributors to a transformational psychedelic journey are sense of safety, quality of intention, the absence of escapist behaviors and distractions, and the feeling of community - all important aspects that we safeguard. By participating in a Synthesis program, you get the opportunity to contribute to pioneering science.

Personalized Care

Throughout the psychedelic supported retreat, we cater to your individual needs by offering specialized workshops and one-on-one consultations with our professional facilitators to ensure you are adequately prepared and equipped to process your experience.

Preparation & Integration

Our programs include pre-retreat preparation and post-retreat integration. Preparation is key for maximizing the potential of a beneficial psychedelic experience and integration is important for prolonging the benefits. We are dedicated to ensuring that our participants understand the unique ways that truffles containing psilocybin can aid in growth and expansion.
