Transformation & Wellness – The Private Retreat

Registration now closed

This is a unique chance to alchemize your personal desires and individual goals. We believe that everybody who gravitates towards the type of experience that we offer at Synthesis is a seeker of greater self-knowing. You are reading this because you feel ready to take an important step, hoping to effect positive changes in your life by using remarkable substances like truffles containing psilocybin.

It is a privilege to provide you with a supportive setting in which you use the neurochemical keys that may help you unlock higher levels of well-being.

The private retreat is your opportunity to experience psychedelics in a setting designed for maximum comfort and safety.  Every aspect of what we offer at Synthesis is fully legal, and your trip takes place under the careful guidance of two dedicated facilitators just for you. These fundamental aspects of the retreat are in place to enable you to relax and immerse yourself totally as you explore untapped facets of your potential in a carefully crafted haven, tailored to your needs to maximize the transformational potential of your experience.

An immersive package

Following our trusted 3-day formula (the larger part of the day is dedicated to each stage of the process; preparation, experience, and integration), the private retreat package includes:

  • The truffles containing psilocybin ceremony, using fully natural truffles, held in private with a dedicated female/male facilitator duo
  • Additional individual preparation and integration coaching sessions before and after your retreat with your facilitator
  • 2 nights of accommodation in your personal deluxe apartment at the Lighthouse
  • Meals and beverages, prepared by our in-house chefs, tailored to your personal dietary requirements
  • Access to the wellness facilities (sauna, etc.) at the Lighthouse

Be our special guest, in great company

The private retreat format has one primary focus: You. We want you to feel at your most comfortable and relaxed, so you can immerse yourself in your personal transformative experience.

You will have your own space – not only physically, but in an emotional/psychological sense too. Your luxury apartment includes its own private living room, kitchen and bathroom.

Finding the others

We have 3 exclusive spots available for this retreat. While the ceremony and the coaching sessions will be carried out privately for each person, you will have the opportunity to connect with the other attendees during meals, as well as during group activities such as the flight instructions, somatic experiencing workshop, and integration circles.

In addition to your personal apartment space, the Lighthouse doubles as the perfect communal atmosphere for sharing this important time-period in your lives with one another. Those who wish to can unwind together in our shared open kitchen, the dining area, or large living room, and delight in the stunning rural setting over fireside chats.

If you would like to bring a loved one to join you for the retreat, we can accommodate this. Please reach out to us to discuss this.

The Ceremony

Bookended by preparation and integration, instrumental aspects of the overall experience which include private coaching sessions, the truffles ceremony itself is at the core of this transformative journey. Two dedicated facilitators will be with you for the entire session, providing any necessary guidance during your experience.

Our process for facilitating the truffle experience is designed to allay physical discomfort and minimize potential nausea. Taking into consideration your intention, sensitivity, and previous experience, we identify the best dosage for you, on an individual basis, to optimize your personal journey. Based on the latest scientific findings, and in accordance with best practices from the psychedelic research community, we ensure your experience will be as profound, safe, and effective as possible.

Venue and accommodation

The private retreat experience will be hosted in the beautiful Lighthouse, near Amsterdam. Please check out some photos below. For further details, please visit our venue page.

Your experience at Synthesis

The Private Retreat is for guests who want to explore the outer reaches of their consciousness in a personalized, private space, with individual supervision from a dyad of expert facilitators, replicating a setup for journeying which has proven effective in psychedelic psychotherapy. Our team will be there for you at every stage of your personal trajectory, offering longer one-on-one preparation and integration sessions than are offered to guests at our communal retreats.

This a legal opportunity to take psychedelics in a safe, individually tailored and expert-guided setting, designed to facilitate productive outcomes, including heightened creativity, clarity on the next steps in your personal journey, and your general development.

Controlled conditions

During the experience, we will control for the following six conditions that play an essential role in every psychedelic experience:

  1. Set. The mental attitude of a would-be psychedelic voyager.
  2. Setting. The surroundings in which a psychedelic substance is ingested.
  3. Guide. A person experienced with non-ordinary states of consciousness who helps to mitigate challenges and channel insights.
  4. Dose. The type and quantity of psychedelic agent; in this case, truffles containing psilocybin.
  5. Session. The entirety of a psychedelic trip, including all activities and rituals.
  6. Situation. The environment, people, and culture from which a person comes to a psychedelic session and to which they return afterwards.

When these vectors are not controlled, 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 how we craft the environment we create at Synthesis, modulating it as needed for each guest. Our recent research in collaboration with Imperial College London has demonstrated the value of having a psychedelic experience in an environment like the one we create at Synthesis, for catalyzing experiences that have a positive impact. We understand working with psychedelics can be intimidating at times, and the supportive setting we curate is designed to address any concerns that you may experience.

An important note: The Synthesis experience is not intended to be approached as a treatment for depression or other mental health conditions. Synthesis is open to everybody who meets our medical and legal criteria. However, psychedelics are powerful agents which should always be used responsibly. A psychedelic setting and experience which is suitable for one individual may not be appropriate for another. For these reasons, a health screening and application process is mandatory for everybody who wishes to join us at the retreat.
