IMMERSION

At Synthesis, safety is our number one priority. Although the psychedelic retreat experience can be beneficial for many, for some it’s not appropriate to consume psilocybin. These include people who have medical contraindications relating to their physical and mental health. Our health screening process aims to mitigate the risk for participants, and we have a dedicated team that assesses each health screening using informed guidelines.  

The following are considered contraindications that would deem someone ineligible to participate in the program. These include, but are not limited to:

• Suicidal thoughts or attempted suicide
• Schizophrenia
• Psychosis (including mania)
• A personality disorder, including borderline personality disorder
• Psychiatric hospitalization
• Any dissociative disorder, including dissociative identity disorder
• Self-harm or self-destructive behavior. Examples include: cutting, bruising, burning or similar self-inflicted wounding, self sabotage, excessive drug and/or alcohol use for multiple days with little to no sleep, regular high-risk sexual behavior, etc.)

Our Facilitation Team includes a Lead Facilitator as well as Retreat Facilitators, all of whom have been carefully trained and supervised by our Lead Facilitator to support you during your journey. Our retreats have approximately one (1) support staff for every two to three (2-3) participants.

In Costa Rica, Synthesis use psilocybin mushrooms. In the Netherlands, Synthesis uses a tea made from truffles, an earlier stage of mushroom development that still contain psilocybin and has psychedelic effects if ingested.

Deciding on dosage is a collaborative and consent-based process. You will discuss dosage in a one-to-one facilitation session on-site at your retreat.

In Costa Rica, generally speaking, the first dose is approximately 1g or 1.5g of psilocybin mushrooms. The second dose can be up to a maximum of 3g of  psilocybin mushrooms.

In the Netherlands, generally speaking, the first dose is 15g of truffles containing psilocybin. The second dose can be up to a maximum of 30g of truffles containing psilocybin.

Our retreats take place at two locations: Costa Rica and The Netherlands. Scroll up to the Venue section.

New Eden: The accommodations are located in one building throughout the grounds and include a mix of single and double rooms. All accommodations are simple and clean, with private toilets.

Holos: The accommodations are luxurious glamping tents that are located throughout the grounds and include a mix of single and double rooms. All accommodations are simple and clean. Bathrooms and showers are mixed-sex, gender-neutral spaces. There is one private bathroom and shower for your convenience.

Room assignments are made at the discretion of a retreat team member, and we cannot guarantee participants single rooms. We will do our best to accommodate family members who wish to stay in double-occupancy rooms whenever possible.

Single participants will be allocated rooms with single beds, separated by gender. If you’re a woman attending alone, you would be sharing with another woman. Couples attending together will share a double room.

The food at our venues is vegetarian, organic, seasonal, and local. Coffee, teas, fresh fruit, and nut snacks are available between meals. The kitchen will cater for any individual dietary requirements and/or lifestyle preferences. We will collect dietary information from participants prior to your retreat.

Participants are responsible for arranging transportation to and from the venue. Synthesis recommends the Staxi taxi service which can be reserved and booked in advance. Additional transportation recommendations can be provided upon request.
