In the Netherlands, magic mushroom therapy is illegal. Since 2008, the sale and possession of psilocybin-containing mushrooms are prohibited, so guided sessions with mushrooms are not permitted. Magic truffles (sclerotia) are legal to buy and possess, and guided truffle sessions are allowed only as non-medical coaching. They take place outside regular mental healthcare, providers cannot […]
FAQ
Does LSD raise blood pressure?
Yes. In studies with healthy volunteers, LSD usually causes a mild to moderate, temporary rise in blood pressure and heart rate, most noticeable in the first hours. Effects scale with dose. Very low doses around 10 to 20 micrograms show little to no meaningful change for most participants, while full doses around 100 to 200 […]
How often can you take psilocybin?
There is no fixed schedule for how often to take psilocybin. It depends on your goals, mindset, and how much time you give yourself to integrate. I cannot verify an exact frequency that suits everyone. For intentional, structured work, many people plan 1 to 3 sessions spread over several weeks or months so there is […]
What is a macrodose?
A macrodose is a higher dose of a psychedelic taken to produce full, noticeable effects, in contrast to microdosing, which aims for sub-perceptual effects. People often describe macrodosing experiences in levels: Level 1 mild shifts in mood and sensory depth; Level 2 brighter colors, slight visual movement, simple closed-eye patterns; Level 3 clear visual distortions […]
How can psilocybin therapy help people make healthier choices?
Psilocybin therapy may help some people make healthier choices by creating space for reflection and value clarity. In a supportive setting, people can recognize unhelpful patterns and set intentions that align better with sleep, nutrition, movement, relationships, and substance use. When insights are followed by integration work, small experiments become easier to start and maintain. […]
Do you offer truffle ceremonies for Belgians?
Yes. We welcome Belgian participants. Our open truffle ceremonies are available to anyone who registers and are not specific to one country. Many people from Belgium choose to join in the Netherlands. We host at our locations in Schiedam, Den Bosch, or Noordwijk, or at your chosen venue within Dutch borders. You can find current […]
What are the risks of combining regression therapy with psilocybin truffles?
Combining regression therapy with psilocybin truffles carries a key risk: heightened suggestibility. In that state, leading or loaded questions can seed confabulation, making it easier for false memories to form. The experience can also be emotionally overwhelming. Intense imagery and symbolism may be misread as literal memory, and strong feelings can blur the line between […]
Do SSRIs like citalopram reduce psilocybin effects, even after stopping?
Yes, some people find that SSRIs like citalopram can blunt the effects of psilocybin, sometimes even after stopping. Experiences vary a lot, from noticeably reduced visuals or emotional depth to almost no effect, while others report no change at all. A common explanation is that long term SSRI use may reduce sensitivity at serotonin 5-HT2A […]
When is the next psychedelic ceremony?
I cannot verify a specific date here. For the latest confirmed date, check the schedule on this Q&A page: next psychedelic ceremony. If you have your own group, a custom date is often possible. For groups larger than three, contact the organizers to arrange it manually. If you are solo or a smaller group, ask […]
Why do people call you Marcel Trip?
People call me Marcel Trip because about 16 years ago I became known locally as the guy you could go on a mushroom trip with. Friends saved my number as “Marcel Trip,” and the nickname stuck. Along the way I picked up other playful nicknames like MarceLSD, tripgozer, and truffelman. It’s just a nickname, not […]
Can I use psilocybin with insulin, Forxiga, Levemir, metformin, and others?
Short answer: I am not aware of well documented direct interactions between psilocybin and insulin (including Levemir), metformin, dapagliflozin/Forxiga, pantoprazole, rosuvastatin, or low-dose aspirin. Still, a session can change appetite, food intake, and activity, so glucose may swing; plan monitoring. With SGLT2s like dapagliflozin, keep up fluids to reduce dehydration risk. Psilocybin is reported to […]
Is a psychedelic guide’s inner state more important than their credentials?
Short answer: both matter, yet a guide’s inner state often matters at least as much as credentials. Research in psychotherapy and psychedelic settings suggests that alliance, set, and setting are strongly linked to how sessions are experienced and integrated. I cannot verify every individual study, but this pattern appears consistently across the literature. Why this […]
