Synthesis is a legal, safe, and modern psychedelic retreat center for professionals who want to experience creative breakthroughs, personal growth, and spiritual development.

We offer exclusive 3-day & 5-day retreats in Amsterdam for individuals who want to utilize moderate-to-high doses of truffles containing to catalyze creative breakthroughs, deepen self-understanding, and feel ready to make their next big ‘leap’ in life.

This is a legal opportunity to take psychedelics in a safe, intentional and expertly-guided setting, geared to facilitating positive outcomes like heightened creativity, clarity on next steps in your life, and general personal development.

To create your experience, we will carefully modulate the following six conditions, each of which plays an essential role in every psychedelic journey:

Set. The mental attitude of a would-be psychedelic voyager

Setting. The surroundings in which a psychedelic substance is ingested

Guide. A person experienced with non-ordinary states of consciousness who helps to mitigate challenges and channel insights. (Read more about our team of coaches.)

Substance. The type and quantity of psychedelic agent; in this case, from truffles containing psilocybin

Session. The entirety of a psychedelic trip, including all activities and rituals

Situation. the environment, people, and culture from which a person comes to a session and returns to afterwards

When these elements are not carefully considered, and psychedelics are not used in a safe, supportive, and structured setting, many of their potential benefits may not be experienced. That’s why we pay such close attention to crafting the environment that we create for your experience. We understand that working with psychedelics can be intimidating; the nurturing environment we create will help to allay any concerns that may come up for you.

With due respect to the powerful nature of psychedelic experiences, and the strong impact that the presence of the others sharing the space can have on your trip, we limit each workshop to 12-16 carefully selected participants. Before joining us at Synthesis for your retreat experience, please complete the Book-a-Call process, including our health screening form, which will be assessed by our health screening team in advance of acceptance into our programs to ensure it is safe for you to come on a retreat with us.
