Experience Psychedelic Transformation

Experience Psychedelic Transformation

With The Pioneers Of Transformative Wellness

A new dawn awaits

We want you to know you are not alone.

It takes courage to take steps towards healing and we want to acknowledge your decision to take control of your future.

The world is experiencing a shift right now and proactive individuals, just like yourself, tired of feeling trapped by their past, and are seeking out expanded states of consciousness as a therapeutic tool for healing and transformation. 

The psychedelic movement is well underway, gaining fast momentum as these natural compounds like psilocybin are proving to be powerful catalysts for healing and growth in people all over the world.

Chances are you’re here because you’re ready to make some real changes in your life and are curious what a guided psilocybin experience might be able to do for you. 

We find that most people who find their way to us have been on quite a journey already. 

They’ve been looking for answers to problems that society has sadly normalised and the pharmaceutical industry has been all-too-ready to prescribe a pill for:

  • Depressive symptoms
  • Addiction
  • Trauma
  • Insomnia 
  • Chronic fatigue 
  • Eating disorders
  • Excessive worrying and anxiety
  • Trouble concentrating
  • Loneliness and disconnection
  • Self-criticism
  • Rumination and negative thought patterns

Ineffective, and at best temporary solutions, have left with us depression and anxiety reaching epidemic levels and entire generations of unfulfilled humans simply going through the motions, hoping for something better.

And no doubt this is not your first stop on your healing journey. 

Many of our clients have explored meditation, yoga, breathwork and other contemplative and spiritual practices.

And while these kinds of practices deliver their own valuable teachings, our guess is that you’re here because you’re looking for a more direct route to an expanded state of consciousness.

An opportunity to “get outside of yourself” and see things from a new perspective, all in an effort to break free from old cycles, make peace with your past and create a brighter future. 

If you’re reading this, there’s a good chance that the reports of the long-lasting benefits of psilocybin have piqued your curiosity.

And for good reason, their impact is hard to ignore.

Apple Genius, Steve Jobs referred to it as one of the most profound experiences of his life.

 

 

Tim Ferris

Best-selling author, entrepreneur and investor, Tim Ferriss has said that all the billionaires he knows, with few exceptions, take this journey on a regular basis. He publicly attributes psychedelics as having a healing influence in his own journey with lifelong depression.

 

 

PlatoNot to mention, Ancient Greek Philosopher Plato formed his foundational beliefs utilizing the psychedelic experience and thus laid the groundwork for all of Western philosophical ideologies.

 

 

But perhaps most exciting is that throughout the world, research indicates that a guided psilocybin journey, can significantly change personality traits that typically remain stagnant in adults.   

Offering access to changes people otherwise write off as impossible.  

Likely because powerful plant medicine has previously been difficult to access and its benefits buried under outmoded ways of thinking. Experienced by only those with the radical boldness to defy convention (and in most cases, the law).   

We were blown away by how much the research shows it truly helps and benefits people, yet access is extremely limited.  

We believe that you deserve legal access to these safe and transformative psychedelic experiences.

So we decided to step in. 

Synthesis was founded to make profound psychedelic transformation available now

Like us, you are change-makers, and we’re tired of seeing you live lives dictated by your past and limited by old thought patterns and paradigms.   

That’s why we have built a fully legal, medically supervised psilocybin retreat center for professionals, like you, to experience personal growth, emotional breakthroughs and spiritual development through expanded states of consciousness.

We offer transformative retreats for forward-thinking individuals who are taking agency in their wellbeing and want to access the life-enriching benefits associated with a psychedelic experience.

Our focus on clinical research and partnerships with leading universities, scientists, and doctors in the psychedelic space ensures we understand how to harness the therapeutic power of these natural compounds and offer tailored-to-you transformative journeys to those seeking profound life-changes.

Now, you can join a retreat of carefully curated professional pioneers who are committed to the betterment of humans and passionate about understanding and expanding the mind.

More Than Just A Trip

Synthesis Retreat - Legal, Professionally Facilitated and Medically Supervised Psychedelic Experienc

 

Our retreats are centered around the ceremonial use of high-dose, legal psilocybin truffles to catalyze this transformation, but the retreat experience goes far beyond that.

We have curated an interdisciplinary team of facilitators, therapists, meditation and breathwork instructors, and designed an experience that blends the best of ancient wisdom, with cutting edge science.

You’ll be joining a community of 500+ pioneering professionals, who have trusted us to guide them through their self-exploration and ultimately, growth.

Our passion for stewarding the psychedelic renaissance has led us to create a retreat program that our participants are reporting as one of the most impactful experiences of their lives.

 


The experience has been nothing short of life changing. From the facilitators, to the people I shared the venue with, everyone was warm, caring, and accepting. The Synthesis team is doing amazing work, long may it continue. I can’t wait to attend again!

How Do We Design Your Experience?

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, or mindset, of the 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.
  • One-to-one. A private session between the guide and the psychedelic voyager
  • Substance. The type and quantity of psychedelic agent; in this case, psilocybin, from truffles
  • Session. The entirety of a psychedelic trip, including all activities and workshops
  • Situation. The environment, people, and culture from which a person comes to a session and returns to afterwards

 

Together, these key elements comprise your psychedelic experience. Each retreat experience is customized further by taking into consideration your intention, sensitivity, and previous experience so that we optimize the best program and dosage for you. Our truffles are administered in a way so as to reduce physical discomfort and nausea. All of our preparation and integration workshops utlize the latest findings and best practices from the psychedelic research community to ensure your experience is as profound and effective as possible.

In committing to this experience, you will be a pioneer in your own right, joining a specially curated list of attendees who are contributing to the next conscious evolution of humanity in a significant way.

 

Your Journey May Include:

  • Peak Experiences

  • Mystical states of consciousness

  • Overcoming destructive attachments

  • Deep and lasting sense of connection

  • Remembering meaningful memories

  • Challenging and confronting visions

 

  • Processing childhood experiences

  • Synesthesia - seeing sound

  • Experiences of intense love and bliss

  • Letting go of suppressed feelings

  • Intellectual epiphanies

  • Enhanced self-acceptance and compassion

  • Heightened states of creativity

 

*While each experience is unique, these are the most commonly reported benefits.

How Would You Rate Your Experience

“I really appreciated the way the Synthesis team was informative, educational and to the point and at the same time sacred and ceremonial. Last but not least I appreciated how they were kept totally secular, that is important to me. What struck me as surprising was that the actual psychedelic journey was a much lesser piece of the overall experience than I had expected. I did expect the surrounding activities to be nice and interesting, but not that they would be essential to the experience and the possibility to learn from it in the way that they turned out to be.”

Jonah, 40, Teacher, Sweden

“The Synthesis team is amazing, from the first email to the emotional goodbye hug they are top class every step of the way. Having been to many spiritual/development focused retreats (meditation, motivational speakers, etc) this was one of the most professionally run and knowledgeable I’ve ever been to. Also, as a complete novice to entheogens/psychedelics it was amazing to see how the retreat catered to those of all levels, helping a rookie like me feel very safe & secure while still keeping those with more experience really engaged! Lastly, they do a great job of curating groups of awesome people, while our group was very diverse there was no drama or issues. Amazing experience, people and team!”

Frequently Asked Questions


About Synthesis

What is Synthesis?

Synthesis is pioneering transformative wellness to help you achieve wisdom-lessing, improved connections, lasting betterment in your mood, outlook on life, relationships, and overall mental wellbeing through medically-overseen, guided psychedelic experiences. We use a combination of Psilocybin truffles, evidence-based wellness programs, and the support of an interdisciplinary team of experienced guides to optimize your healing journey.

Who is Synthesis for?

Synthesis is for people who are looking for the best in mental health and wellness practices. We work with professionals of all walks of life and ages, from those who are new to expanded states of consciousness, as well as the highly experienced.

How does it work?

You begin by scheduling discovery call with your Synthesis guide to see if a Psilocybin retreat is right for you. Before your call, we will ask you some personal and medical data. Then, we’ll book your dates, send you your preparation information, and introduce you to your group and lead facilitator for your retreat.

How much do your programs cost?

Our retreat types differ in time and value, and therefore in price. Please refer to the specific retreat descriptions above for more information and price.

Are there scholarships available?

We have scholarships available. Please ask for on Your Exploration Call what is possible for you.

I'm looking for psychedelic therapy. Can you help?

It’s important to know that we do not offer any therapy. While our protocols and trainings are based on the best therapeutic practices currently available in this field, scientific research is still working on what constitutes proper therapy. What we offer is a safe and compassionate space where you can explore your own consciousness with all the beauty and darkness, love and difficulties that reside within it. We adhere to the best professional standards, but do not give treatment nor actively work with depression or traumas at this time.

We're working hard to develop our capacities which will allow us to offer legal therapeutic treatment in the near future. We're happy to keep in touch over email as we fulfill this long-standing ambition.

On Psilocybin

Are psilocybin truffles really safe?

According to recent studies, psilocybin mushrooms (which have the same active ingredient as truffles) are the safest drug currently known - safer than tobacco, cannabis, and alcohol. These substances are non-addictive, non-toxic, and, when taken within a structured setting under the guidance of medical professionals, hold little to no risk.

What is Psilocybin?

Psilocybin, upon entering the body, is quickly metabolized into psilocin, which is responsible for the well-known psychedelic effects. Psilocin acts on serotonin at the 5-HT2A receptor, increasing the amount of serotonin available in the brain, and producing profound changes in perception, such as visual and auditory hallucinations, tactile perceptions (such as tingling or warmth), and synaesthesia (the merging of senses).

Users of psilocybin report entering a profound state of mind where the usual limits of consciousness are expanded. Realizations about the self and the universe may come to the forefront, and people will often describe feelings of unity, interconnectedness, and unconditional love. Studies have shown that psilocybin can induce a mystical experience and that this positively correlates with the benefits that users report following the trip.

What is the dosage used in the retreat?

We determine our dosage together with you during your 1-1 conversation. What we recommend varies, depending on your intentions, previous experience, your sensitivity to expanded states of consciousness, and your anxiety level on retreat. On average we use the clinical standard of 30mg/70kg of psilocybin and psilocin. When it is your first time, we recommend a slightly lower dose to get more comfortable with these states of consciousness. If you have more experience or a strong contemplative practice, we are open to provide much higher dosages.

What's the dose of psilocybin truffles I will be given?

We determine your dosage together with you during your 1:1 conversation. What we recommend varies, depending on your intentions, previous experience, your sensitivity to expanded states of consciousness, and your anxiety level on retreat.

On average we use the clinical and safe standard of 30mg/70mg of psilocybin and psilocin. When it is your first time we recommend a slightly lower dose to get more comfortable with these states of consciousness.

I'm on antidepressants. Does this disqualify me from attending a retreat?

The simple answer to this question is that we review applications on a case-by-case basis based on both psychological and medical history, as well as current medications, to look for any contraindications before we can formally accept or not accept an applicant.

Our medical team is sometimes able to tell you under which conditions it’s safe for you to come on retreat, for example if you are able to taper off under correct supervision and receive sufficient aftercare after your retreat.

Everyone who we can’t accept at this time gets put into a contact list where we will monitor and reconnect as we expand our capacity to take on more and more people through building up and improving upon our support capabilities - which include therapeutic support pre-retreat and post-retreat. 

The Synthesis Experience

HOW DO I BOOK DIRECTLY?

We would like to make sure you have all your questions answered and trust a Synthesis retreat is right for you. That is why the first step towards joining a retreat is to book an exploration call with us. During this call, we'll explore your intentions, your questions and any concerns you might have. We'll also share more about our programs and explore if we are a good fit.

However, if there is a reason you do wish to attend the call, or would like to make an urgent booking, here is what to do:

Click, BOOK A CALL and follow the process outlined. While you pick your date and time, complete a few questions to help us personalize your experience.

Next, complete the medical screening process, and if approved, you will receive an email from us confirning your call. To bypass the exploration call stage simply reply to that email (or email us directly at suppot@synthesisretreat.com) and indicate the reason for not attending the call and the dates and program you would like to attend. We will correspond through email with you.

WHAT IF I'M NOT MEDICALLY APPROVED?

In order for us to accurately assess your suitability and safety for a psilocybin journey, as well as to provide you with a personalized experience during your retreat, we would love to get to know you better first and see whether Synthesis is right for you.

If you screener identifies anything that requires a closer look by our medical team, we will wait until we get clearance from them. In the mean time, we will postpone your Exploration Call while we work with you on your case.

There are three possible outcomes of this review:

  1. Your Health Screener is approved and you are invited to reschedule your Exploration Call
  2. To get a better understanding of your condition, we may request some more information from you. This may be over email or in the form of a brief call.
  3. If we don't feel as though we can support you safely through your psilocybin experience, we may decline your application and therefore your Exploration Call (if this happens, we will send you an email with further details) Throughout this entire process, we handle your information with the utmost care and consideration for your confidentiality.

We appreciate this may feel like a roadblock and we want you to know that our medical team will work with you, with your best interests at heart, to determine the best course of action. Thank you for your patience and understanding. Your safety is our primary concern.

WHY THE RETREAT MODEL?

Studies have shown that the context of a group retreat and having experienced guides are essential ingredients to properly optimize for safety and getting the most out of a psychedelic experience. From years of retreat experience we know the value of this experience is rooted in the whole process, from being able to surrender fully because there is medical and professional support, to the meaningful relationships you will build with others.

HOW WILL THE PSYCHEDELIC SESSIONS BE SET UP?

We provide a comfortable indoor space with mattresses to lay down on, eye shades, and profound music. There are also creative spaces inside and outside to explore. In creating an optimal environment for your psychedelic experience, we combine ceremonial aspects rooted in age-old tradition with modern approaches that have proven, in scientific research, to be effective at facilitating a deep, meaningful experience.

IS THERE ANY PREPARATION AND INTEGRATION WORK INCLUDED WITH THE RETREATS?

Upon arrival, guests participate in both group and individual workshops to help prepare them for the psilocybin ceremony. On the day of the ceremony, guests participate in a breathwork session and are carefully supported by experienced practitioners, including an on-site medic as they experience psilocybin in a therapeutic context. After the ceremony, guests participate in group and individual workshops focused on integration before customers return home. Additional preparation and integration support is also offered digitally outside of in-person retreat dates.

WILL MY PERSONAL INFORMATION BE CONFIDENTIAL?

We keep all personal information confidential, none of it will be shared with third parties.

DO YOU OFFER 1-TO-1 GUIDED SESSIONS IF I PREFER TO DO THIS IN PRIVATE?

Yes, we do! Please see our private retreat offer for more details. We also offer 1-to-1 preparation and integration coaching as an option during our group retreats, for an additional fee.

CAN I DO MORE THAN ONE RETREAT?

Yes, you can. A second retreat can be a quite different experience, certainly not just a repetition. In case it‘s your second overall psychedelic experience, many people tend to be even better prepared and relaxed as there is a familiarity that allows them to let go or direct their experience even more. For experienced psychonauts on the other hand, each experience can have its own focus or topic, exploring different aspects.

CAN I STAY AN EXTRA NIGHT AT YOUR VENUE?

You are welcome to stay an extra night at the venue either pre-retreat, post-retreat or both. We charge an additional cost of $200 for each night.

Please note that because your extended stay is beyond our normal retreat schedule, you will be responsible for your own transportation and your own meals during this time. We will be very happy to assist or point you in the right direction for both. Your apartment’s kitchen is well equipped for cooking and there are many restaurants and grocery stores within a short walk of the venue.

Check in time early arrival: between 12pm and 19:00 / 7:00 PM* Check out time late departure: 10:00 AM

  • We kindly ask you to communicate your arrival time to our venue manager, so that she can get everything prepared for your arrival.

You are welcome to use the sauna and the facilities in your apartment, but the access to the rest of the building will be restricted. The retreat team is preparing for your retreat, and so the common areas like the church and ceremony space are off limits. We appreciate your understanding.

WHAT’S THE IDEAL FLIGHT SCHEDULE FOR MY ARRIVAL / DEPARTURE?

Arrival to Schiphol International Airport: Please keep in mind that you should land by 10.30 AM CEST (local time) at Amsterdam Airport on the first day of your retreat to make it through customs on time. The shuttle service to the venue leaves at 11.30 AM CEST.

We are aware that the time window for arrival might be limited. If you have trouble booking a flight that lands before 11.00AM on the first retreat day, please contact us so we can help you with the travel schedule.

Departure from Schiphol International Airport: We advise to book your returning flight after 19.00pm CEST on the day of departure, as the retreat will wrap up at 16.00pm CEST and drop off will be at Amsterdam Central Station or Schiphol International Airport at 16:30 - 17:00pm. This should give you sufficient time to make it through customs without any unnecessary stress.

WHAT’S YOUR TAKE ON COUPLES (OR FAMILY MEMBERS, FRIENDS) ATTENDING TOGETHER?

Coming together or not is a very personal decision. Many couples join us for a retreat together and have a wonderful time. Coming together can be a very bonding experience for both of you, a transformative experience to share and remember. Our Director of Operations actually came as a participant to one of our first ceremonies with her husband. She often reminisces with a smile that the experience brought them much closer together.

In some cases, it might make sense to come alone. If you have a personal issue you’d like to work on during the retreat, having your significant other around could be a distraction for you. For instance, you might end up worrying about them and be unable to focus on your own process. In this case coming separately might be better.

Have you already decided that you’ll come together? Excellent. This is how it works: Both of you need to sign up for an Exploration Call, which is followed by our Health Check. The Health Check is a mandatory step for each of you. You may schedule your call together or separately, that’s up to you, but please let your exploration guide know in advance if you come together on your call.
