For thousands of years, humans have used “magic” mushrooms to develop a deeper connection to self, community, and purpose.
When used with intention in a safe space, this remarkable plant can make a profound impact.
Our beautiful and peaceful location just outside of Amsterdam is the perfect setting for a comfortable, transformative mushroom experience.
It is our mission to synthesize cutting-edge research with ancient practices to help people achieve true freedom. With professional guidance and facilitation, you will be able to integrate your mushroom journey at Synthesis towards a more fulfilling, joyful life.
A new dawn awaits you at Synthesis.
“I feel that I made one of the best decisions of my life attending the Synthesis retreat. My life has improved on numerous fronts and I have adopted new practices (e.g., daily meditation and free-flow writing) to sustain my new outlook on life. And the relationships that I built with everyone else there are some of the strongest I have ever felt — an unexpected dividend of this experience.”

"I felt like I let out so much emotion and now I can take stress easier because I have more room for it. I also still feel the beautiful compassionate love that I experienced and spend more time thinking about how my interactions affect others. Before, I struggled to let go of alcohol and now it is effortless because I have no interest in it. I love that, because I feel healthier and much happier.”

“Just wanted to commend and thank you all for an amazing retreat. The care and attention to each and every person and every detail was very thorough. [Synthesis] is probably the best facilitation and framework for this type of experience I’ve encountered.”
