Which conditions guide us to meaning in a psychedelic journey?

We know that a high-dose psyched*delic experience goes far beyond just the substance. It’s the synergy of conditions that allows insight to emerge, integrate, and endure.

These conditions act as a living orchestra, where every element works in harmony to maximize the potential of psyche*delics to catalyze meaningful and lasting change.

At Synthesis, every facet of our Immersion retreat is carefully designed to help participants
open to profound insights, emotional release, and lasting personal growth.
Immersion is a 7-week arc of inner work that includes:
✨ 3 weeks of guided preparation
✨ A 5-day retreat with 2 truffle ceremonies
✨ 3 weeks of integration and support
To find out more about our philosophy behind Immersion, book your free discovery call today.
📅 Our next Immersion retreats are scheduled for April 26–30 and August 2–6, 2026.
