An Immersive Psychedelic Transformation Program | 7-Weeks Of Deep Exploration & Awakening

Expansion is for the pioneer

Profound psychedelic transformation does not happen by chance.

There is both a science and an art to creating the right conditions under which the true power of psychedelics can be harnessed. 

Data from our partnership with Imperial College in London, as well as experience from guiding journeys with over 500 participants, has shown us that the key to the most impactful retreat is correct and thorough preparation, and supportive integration.

Dedicated to designing cutting-edge and breakthrough retreats, we wanted to continue to build on our offering, and use the unique window of opportunity that psychedelics catalyze to realize lasting change and insight. 


Introducing: Expansion

The world’s first immersive psychedelic transformation program.

No ordinary retreat, this all-encompassing, 7-week program is designed for deep and lasting transformation. 

A 5-day stay at our world-class retreat center in The Netherlands, supported by 3 weeks of pre-retreat preparation and 3 weeks of post-retreat integration digital workshops — designed to help you envision, create and integrate the positive change you would like to see in your life.

This retreat is an exclusive, carefully curated experience with other professionals just like you. 

Our Journey Together

Expansion begins three weeks in advance of the actual retreat, with weekly preparation calls with your group and facilitators. During the 5-day retreat, we build a foundation in contemplative practice. Every day we begin and end with meditation. 

The first ceremony is a new experience we call “immersion”, which consists of a medium-high dose to fully arrive at the venue and explore your own consciousness with truffles containing psilocybin in the different spaces of our venue.

The second one is a high dose with a unique soundscape collaboratively designed with one of the world’s experts on consciousness, mysticism, and resonance.

When we listen to specifically designed sound, we can go into a transcendental state where we lose awareness of the self, or we become that which we’re observing, and we no longer are aware of the observer. We become the sound that we’re listening to.

To prepare you for this 7 hour sound journey, this retreat is supported by a multitude of additional practice to invite you in the optimal state of body-mind. Every day we begin and end with a meditation practice. Additionally, there are three breathwork sessions, as well as three 1:1 coaching sessions, and full access to our wellness area. 

After your retreat, you will reunite with your retreat co-travellers online where we will focus on the integration of these expanded states of consciousness. Together, we will engage in guided interactive practices and teachings, explore the groups questions and challenges as you move back into your social spaces, from the personal to the professional our integration workshops will deepen and expand the unique key insights of your psychedelic experience.


Why 7 Weeks?

7-weeks might sound like a big commitment, and in many ways it is - a commitment to yourself. 

However, we appreciate the busy nature of your life and this program is not intended to add to your already pressing schedule. If you are unable to make the calls, for any reason, we will send you the recordings and exercises so you can do them at a time that suits you.

One of the reasons Synthesis is so in demand by professionals is to reduce stress in their lives and help to set a more relaxed pace.

With this in mind, we have designed the pre-and post-retreat experience to easily fit into your life through weekly mastermind calls with your fellow travelers.

The 7-week program makes the most of this larger window of plasticity to grow your presence, self-acceptance, focus, and expand your range of states of consciousness in your daily life.


Expansion is designed for you if:

  • You are truly committed to creating lasting change in your life

  • You would like to learn how to integrate contemplative practices like meditation and breathwork into your daily life

  • You are interested in forging deep and meaningful connections with other like-minded individuals 

  • You are new to psychedelics (we specifically recommend this program for first-time travelers)

  • Have experience with psychedelics and are ready to access deeper insight and transformation through immersive work




Due to COVID-19 Restrictions, Our Retreat Center is Currently Closed

Due to the ever-changing COVID-19 global health impacts, travel restrictions and extended lockdown in the Netherlands, we’re still unable to reopen our wellness retreats.

Please note: As we’re able to resume retreat operations, you’ll be contacted when we’re able to begin the screening process that is required prior to offering you a retreat date. We will prioritize retreat bookings based on the completion of screenings and approvals.


Program Schedule

Preparation (week 1 - week 3)

Being prepared for your psychedelic experience begins weeks in advance. Drawing upon scientific and medical research, as well as the contemplative arts, our professional facilitators lead live weekly group workshops preparing participants . All of which we will return to on the retreat.

(Click below to read more about each week)

Week 1: Preparation through Practice

Whether expert or novice, we come together with a beginners mind. In week one we get to know our group and we begin with simple breathwork and noticing meditations as home practice. Connecting with the breath as the anchor point.

Week 2: Awareness through Active Listening & Noticing

Listening actively is an art all unto itself. In this workshop we will tap into a process of deeply-rooted listening to ourselves, others and life. Being the listener is one of the most simple, yet advanced practices on the path.

Week 3: Opening Up Around Resistance

Resistance can be a powerful force for transformation, if you can see it as such. Together we will explore resistance, acceptance and practices that support us to remain present and grounded, even if we lean into the sharp edges of reality.

The Retreat (Week 4)

The retreat itself is 5 days with 2 truffles containing psilocybin sessions. The first one is a medium-high dose to fully arrive in the retreat and explore your own consciousness, as well as the possibilities of the retreat. The second one is the high dose with a unique soundscape designed with one of the world’s experts on resonance, mysticism, and consciousness. This retreat is supported by a lot of additional practice to really put you in the right state of mind for this experience. Every day we begin and end with a meditation practice, as well as additional breathwork, and 3 x 1:1 coaching sessions, and use of our wellness area.

Integration (Week 5 - week 7)

Where preparation is essential for maximizing the potential of a psychedelic retreat, integration is important for prolonging the benefits. You will witness a new self, yet an old similar world. While a psychedelic retreat can offer a potentially otherwise unachievable window of opportunity in the short term, whether this translates into lasting habits depends on integration. How to move from the potential you’ve experienced, into the actuality of your day to day life?

Week 5: Somatic Integration

Coming home with a renewed sense of possibility and vision is both an exhilarating experience, as well as a potential difficult one. Renewed sensitivity while facing old triggers is the path to navigate. Based on the Accept, Connect, & Embody protocol developed by Imperial College London, we will provide support in accepting the challenges, however they may arise. Connect to what is empowering and nourishing, and to remain feeling everything as deeply as possible by attending to the body.

Week 6: Social Integration

In a world where language around these expanded states of consciousness is rare, and the experience themselves are frequently misunderstood and easily misjudged, the challenge is to speak your new authentic truth in the face of disagreement and unknowing. How do you remain integrated in the social sphere? We will talk about the discernment of sharing.

Week 7: Synthesis — the culmination of elements

This will mark the last week of Expansion, a week where we will bring it all together. Looking back, we make inventory of what has changed, and plant intentions to remain connected moving forward.

Naturally, demand for this new experience is high and our available dates tend to fill up fast.

We are proud to be stewards of the psychedelics renaissance, demonstrating our position at the forefront of this movement through our partnerships with institutes like Imperial College London, and world experts on resonance, mysticism, and consciousness to deliver a completely unique soundscape experience. 

We thank you for your trust in us and we look forward to sharing this experience with you.
