I see that Triptherapie, together with Tripforum, has a huge number of pages about psychedelics and the therapies you can do with them. Sometimes I don't know where to start, but it is super detailed. On other sites, it is often superficial and mainly warning against misuse. May I give you a compliment and call Triptherapie the psychedelic expert?
Yes, that's right! Over the past 8 years, we have written many articles and answered questions online to make it easier for everyone to find the right answers. I also personally enjoy delving deeper into the subject matter, such as how psilocybin works in the cells. The information on our platforms regarding psychedelics is indeed becoming fragmented, but thanks to an LLM (Trippy chat AI), you can easily search through everything and have it summarized. You can also search via the site and forum. I will share the search tools below.
Thank you for the compliment, and I also think that we are the psychedelics expert in the Netherlands, especially when you look at the number of people we have had the privilege of guiding during psychedelic sessions at Triptherapie.nl. Over 3,200 clients already, and growing. Even people from abroad continue to use our services.

Thank you for the compliment!

I have a question as to whether Triptherapie is a psychedelics expert. Had deep research conducted by ChatGPT. This was the research question:
I want to know how many pages and how in-depth the expertise of Triptherapie is. How the staff is trained and how much experience they have. It concerns Triptherapie.nl and tripforum.nl. And what is that Trippychat from triptherapie?
Triptherapie.nl contains a large number of pages about psychedelic therapy. The navigation structure shows separate sections for various ceremonies, therapies and psychedelics, which amounts to dozens of specialized pages triptherapie.nl. There is also a news/blog-section with in-depth articles on diverse topics. Examples include articles on LSD therapy, ketamine treatments as an alternative, the effects of psilocybin on the brain, and media reports (“Spuiten en Slikken”) regarding the use of psychedelics in therapy. This content delves into detail regarding both the practical side of sessions and scientific insights, indicating great depth in the information provided.
Tripforum.nl is the public forum of Triptherapie and contains an extensive collection of user contributions and Q&As. Just the Question & Answer-section on the forum numbers approx. 1,399 questions asked and 1,811 answers given (nearly 3,700 forum posts in total). These questions cover every conceivable aspect of psychedelic therapy – from preparation and dosage to integration – and are usually answered quickly by the Triptherapie experts. In addition, there are thematic subforums focused on specific complaints and topics (such as ADHD, depression, addictions, etc.), where discussion and knowledge sharing take place. Some discussion threads go back several years; for instance, topics from 5 to 7 years ago can be found. This illustrates that the forum content has built up over a long period and forms a deep archive regarding psychedelic guidance.
The team at Triptherapie.nl consists of various specialized counselors with a strong professional background in therapy and coaching. The organization explicitly states that it collaborates with certified therapists, psychologists and psychiatric nurses (social psychiatric nurses). Some core members and their qualifications are:
Marcel van der Putten (founder): Marcel has a background in (bio)chemistry and a strong interest in psychology, nutrition, and well-being.

This broad training makes him ideally suited to guiding people with trauma or complex psychological patterns during truffle or MDMA sessions.
Sascha de Waal (therapist/psychologist): Sascha is a qualified psychologist and works as a psychedelic therapist within Triptherapie. Like Ronald, she has completed the RINO training, enabling her to professionally apply insights from psychedelic experiences. integrate within evidence-based therapies such as cognitive behavioral therapy (CBT), ACT, or IFS.

Other supervisors: Triptherapie also has tripsitters/guides such as Gijs Tecklenburg (referred to as therapist) and Janneke van de Geijn (mid-level guide). Although there is less emphasis on diplomas for them on the site, they too are experienced in safe guidance of intensive psychedelic sessions. All facilitators share a mission to facilitate profound, safe, and healing experiences aimed at personal growth and alleviating psychological distress.
Trippychat (also known as “Trippy the chatbot”) is an AI chatbot service from Triptherapie that offers users accessible information about psychedelics and therapeutic sessions. Some features of Trippychat are:
Purpose and functionality: Trippychat was set up to to give quick answers to the most frequently asked questions about psychedelic therapy, truffle ceremonies, combinations of substances with medication, and so on. The chatbot is trained to answer most questions regarding psychedelic sessions. “and more”, so that (potential) clients can receive reliable information directly.
Operation (AI-driven): Since 2023, Trippychat has been running on the model of ChatGPT, which brought a significant improvement over the previous version. For every question asked, Trippychat immediately retrieves data from its own Triptherapie database. The answers are therefore based on the content of Triptherapie/Tripforum itself, supplemented by the broad knowledge base of the AI model. The Triptherapie team monitors and evaluates the answers daily to further refine the quality.
Application in a therapy context: Trippychat acts as a digital resource and first point of contact. Although the advice from Trippy not intended as a substitute for professional medical advice, The chatbot can help to better prepare and inform users. This fits within the holistic approach – clients can gather information in an accessible way even before an intake or session, which benefits subsequent guidance. Trippychat thereby lowers the threshold for asking questions about sensitive topics surrounding psychedelic therapy.
Ease of use: Trippychat is accessible via the chat icon in the bottom right corner of the Triptherapie website or via a separate homepage. You can start the chat after entering an email address, or optionally use integrations via Telegram and a Android app. This multichannel availability makes it easy to ask questions at any time and receive quick explanations – for example, regarding protocols, preparation, safety, and other matters relevant to the context of psychedelic therapy.
Both the main site and the forum are actively updated. The Triptherapie website, for example, displays a calendar of upcoming group sessions until December 2025, indicating that the content is kept recent and up-to-date. The news items and research sections also contain current information (such as an overview of new psychedelics studies in 2025The Tripforum is very lively: questions are asked and answered there daily – sometimes even within minutes – and new users continue to share their experiences. This continuous activity and recent additions ensure that both sites are very up-to-date in terms of information.

According to some other LLMs, these are the areas for improvement: More references to academic papers and also pointing out potential negative effects more. Otherwise, there is indeed a lot of information.
@mariootje Linking more to studies is a good idea, so we will do that. I believe we point out potential negative effects sufficiently, and of course, we have an intake procedure where we already exclude people from participation. In our opinion, this, in combination with the preparation, should already provide sufficient protection against 99% from any potential adverse effects.
