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.
