Triptherapie has been a leading provider of psychedelic sessions in the Netherlands since 2018 and has already guided more than 2,500 clients. The offering includes both individual psychedelic therapies (private sessions) as group ceremonies (two-day retreats) with legal psychedelics. A characteristic feature is the holistic approach: in addition to the sessions themselves, every client receives extensive pre- and post-care, including a personal intake, advice on preparation (diet, supplements, mindset), and integration afterwards. Below is an overview of all services, the locations where they are available, and which therapists work there, including details about the therapies, ceremonies, and specializations of the facilitators.
Triptherapie offers one-on-one sessions (also duo sessions for two people) under professional guidance. We work exclusively with legal variants of psychedelics: psilocybin truffles, psiloflora (passionflower truffles), and legal analogues of LSD and MDMA. Which substance is used depends on the client's needs and contraindications. Every therapy starts with a thorough intake and personal preparation. Based on the intake, the client receives tailored advice – for example, dietary and supplement recommendations to optimize neurochemistry – ensuring they are mentally and physically ready for the session. The session itself takes place in a controlled environment with an experienced tripsitter/therapist, followed by a debriefing and integration to permanently process the insights gained. Some forms of individual trip therapy include:
Psilocybin/Truffle Therapy: Private session with magic truffles (legal source of psilocybin). Psilocybin is known as a widely applicable therapeutic tool. Triptherapie converts this “jack-of-all-trades” for, among other things, depression, addictions, and social anxiety. With the right preparation, psilocybin can even be effective for trauma and PTSD. Depending on the need, the dose can vary from microdosing to a heroic dose for very deep experiences. Psilocybin is therefore suitable for both psychological recovery and exploring creativity and spirituality. (Synonyms: truffle therapy, truffle session*.)*
MDMA therapy: Individual session with a MDMA analogue (active legal variant of MDMA) which is primarily used in the processing of trauma and PTSD. MDMA causes few hallucinations, but strong feelings of euphoria, safety, and empathy. This creates an ideal therapeutic window: the client can talk about painful memories without fear or blockages while feeling emotionally stable and connected. In this way, an MDMA session functions as a “accelerator of exposure therapy” where trauma triggers are relived and processed in a safe, positive state.
LSD therapy: Individual session with a LSD analogue (legal variant that is converted into LSD in the body). An LSD trip lasts considerably longer than other psychedelic sessions; therefore, LSD therapy is primarily recommended for clients who already have experience with shorter trips. The properties of LSD can be useful in, for example, the treatment of addictions or to facilitate creative breakthroughs. LSD therapy is used less frequently for depression or anxiety, unless specifically desired due to the prolonged introspection. (NB: The LSD session is legal thanks to the use of an analogue.)
Hippie Flip (MDMA + psilocybin): A combination session where MDMA and psilocybin are used simultaneously. This is offered to people who would benefit from the deep insights of a high dose of psilocybin, but who fear the intensity of a full trip. The addition of MDMA has an anxiety-reducing effect and promotes feelings of self-love and surrender, whereby the reduces the chance of a so-called “bad trip”. Small-scale research and experience show that a hippie flip can facilitate the emotional breakthrough: it increases self-compassion, love, and gratitude, while negative emotions become less prominent. This combination is therefore an interesting option for clients who are nervous about a regular truffle trip but still want to achieve deep therapeutic results.
Wizard Flip (LSD + psilocybin): Another combination session that Triptherapie offers is the wizard flip, whereby LSD and psilocybin are taken together. This mix is often chosen by clients who a very visual trip experience wishes, but without the extremely long peak of pure LSD. The truffles temper the duration of the LSD peak, as it were, while both substances together create a unique synergy. People with obsessive-compulsive disorder (OCD), in particular, regularly opt for a wizard flip to combine the therapeutic benefits of both psilocybin and LSD. This session offers intense visions and insights, but is slightly more manageable in terms of duration than a pure LSD session.
Psiloflora (Psilohuasca): Triptherapie also offers alternatives for those interested in a ayahuasca-like experience. Psiloflora is a combination of psilocybin truffles with passion flower (a mild MAO inhibitor). This is also known as psilohuasca mentioned, since the MAO inhibitor the trip strengthens and extends, comparable to a DMT/ayahuasca experience. Due to the addition of passionflower, the journey becomes more spiritual in nature and lasts longer than a regular truffle session. Because of the intensity and longer duration, Triptherapie recommends psiloflora only to clients who have already had previous psychedelic experiences. This option is particularly chosen by individuals who are explicitly seeking deep spiritual insights similar to ayahuasca, but within the legal framework of psilocybin. (NB: Participation in psiloflora requires additional screening, for example, exclusion of certain medications such as SSRIs/SNRIs due to interactions.)
All the above therapies are always embedded in a process with personal guidance. Beforehand, the client first completes an extensive form. online intake in, based on which Triptherapie assesses whether a session is safe and suitable. Upon agreement, a date and a personal counselor are scheduled, and the client receives tailored preparation advice (think of dietary and supplement adjustments, reading tips, assignments). During the session day, the client is guided by the chosen tripsitter/therapist on the desired location (at home or at one of the Triptherapie locations). Immediately after the session and in the days that follow, the facilitator helps with integration, so that the experience gained can be sustainably transformed into positive life change.
In addition to individual programs, Triptherapie organizes monthly group ceremonies – typically two-day retreats with overnight stay – in small groups. These ceremonies usually take place at their own location. Psychedelic Loft in Schiedam (South Holland) and are all-inclusive (guidance, psychedelics, food, and accommodation included). Much attention is also paid to personal preparation and safety during the group sessions: every participant must complete an intake beforehand, receives personal advice for preparation, and support with integration afterwards. Themes are used per ceremony, along with carefully curated music, for an optimal experience. Furthermore, Triptherapie maintains small groups (maximum 5 or 6 participants) to guarantee sufficient individual guidance and even moments of privacy. The main group services are:
Truffle ceremony (group ceremony with psilocybin): A group trip under the influence of magic truffles, with maximum 6 participants per ceremony. Because magic mushrooms are not officially legal in the Netherlands, Triptherapie works with truffles – hence the name truffle ceremony, which means the same as a psilocybin ceremony or mushroom ceremony. The truffle ceremonies of Triptherapie distinguish themselves through extras that deepen the experience. For instance, every participant receives personalized advice beforehand based on the intake and the chosen theme of the ceremony. A few days before the ceremony, participants receive, for example, video and reading tips related to the theme, plus instructions such as dietary adjustments and small assignments for mental preparation. During the ceremony itself, if desired additions be deployed: participants may choose at the last minute for psiloflora as an extra element in their truffle trip. Psiloflora (truffle + passion flower) can slightly prolong and deepen the trip, provided there are no medical objections. The location For the truffle ceremonies, the Psychedelic Loft in Schiedam is usually used – an atmospheric loft specially decorated with art and patterns to enhance the tripping experience. The loft is conveniently located (near Rotterdam/The Hague, easily accessible, and with free parking), and participants can enjoy a drink after the session at no extra cost. stay overnight at the location. A truffle ceremony costs €550 per person for the complete retreat. For upcoming dates (e.g., March 29, 2025, June 14, 2025), interested parties can reserve after approval of the intake.
MDMA group session (MDMA ceremony): A group-oriented MDMA ceremony of maximum 5 participants. Each participant receives individual preparatory assignments in advance, and on the day itself, a collaborative and carefully structured process takes place. During the first 1 to 2 hours of the ceremony, the group forms a circle and participants share their stories and intentions to create openness and connection. Subsequently, all participants take a MDMA analogue, and as soon as it starts working after ±45 minutes, a starts silent introspective phase of approximately 2–3 hours. During this phase, there is no talking; instead, specially selected individuals provide guidance. music the inner journey of each participant. The choice of music plays an important role and is aimed at evoking positive emotions and leading back to inner memories in a loving way. For most participants, this phase feels like a warm, empathetic adventure inward. After the silent period, the group comes together again for conversation: participants are given the space to share experiences and feelings. to share with each other and with the guidance. Just as with the truffle ceremony, the positive therapeutic effects are significant: MDMA opens the heart, improves mood, and reduces anxiety, allowing participants to talk about trauma, for example, while feeling safe and euphoric. This promotes reframing painful memories in a positive light and can support lasting emotional healing. The MDMA group sessions also take place in the loft in Schiedam, including overnight accommodation, and cost €650 per person. New dates are regularly scheduled (e.g., April 19, May 9, June 28, 2025), for which interested parties can register after an intake.
(In addition, Triptherapie also refers to on the website “Mushroom ceremony”, “Psilocybin ceremony” and “Psilohuasca ceremony”. These terms are largely synonymous with the services mentioned above. A mushroom or psilocybin ceremony refers to a truffle ceremony (use of psilocybin truffles). A psilohuasca ceremony refers to a truffle ceremony *with* an MAO inhibitor – effectively the psiloflora option, which is available with every truffle ceremony as of June 2023.
Safety and quality are paramount at all group ceremonies. Every participant must complete the intake form beforehand and obtain approval to rule out medical/psychological risks. Due to the small group size (5–6 people), there is plenty of personal attention: Triptherapie ensures sufficient facilitators per group and coordinates the dosage tailored individually for each participant for an optimal experience. During the ceremony, there is space for individual sessions if desired (e.g., briefly withdrawing with a facilitator), so that everyone feels safe and heard. Participants receive professional aftercare and can share their experiences; Triptherapie also has a forum (Tripforum) and refers to reviews from previous customers for insight into the experiences of others.
