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 […]

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 […]

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 […]

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 […]

Short answer: there is no convincing evidence that psilocybin from mushrooms or truffles raises GLP-1 or acts like a GLP-1 agonist. The appetite drop many people notice during a psychedelic experience is more likely tied to serotonergic effects, especially 5-HT2A activation, which can shift attention away from food and reduce food reward. Both GLP-1 drugs […]

Short answer: early evidence says yes. In adults with major depression and suicidal ideation, a randomized trial in the American Journal of Psychiatry reported that starting low-dose buprenorphine about 48 hours after a single ketamine infusion was associated with a larger and more sustained reduction in suicidal thoughts over four weeks compared with ketamine plus […]

Some people choose LSD therapy over psilocybin not because it is more effective, but because of how the experience feels. The clinical literature is currently larger for psilocybin in areas like depression, end-of-life anxiety, addiction, and PTSD, which reflects research focus and session logistics, not a universal advantage. People often describe psilocybin as inward and […]

Short answer: In the Netherlands, BIG-registered therapists may not offer psilocybin, LSD, or MDMA as regular mental healthcare outside approved research or another specific legal basis. Working with truffles is not a regular GGZ treatment. A BIG professional can take part in non-medical psychedelic activities only outside their BIG role and with a clear, provable […]

Guided truffle sessions in Amsterdam typically start with an intake to discuss intentions, background, and practical details. On the day, the facilitator prepares the setting, selects an appropriate dose, and offers support throughout a session that usually lasts several hours, followed by a short integration talk. You do not need to buy truffles yourself. The […]

Yes, psychedelic therapy can still be helpful for working on jealousy even if you have used many substances before. Therapeutic use is different from recreational use because it centers on intention, guidance, and integration rather than chasing effects. Past drug use does not make therapy pointless. It may mean you are less focused on the […]

For an experienced tripsitter in the Randstad, start with Triptherapie. Their network covers much of Amsterdam, Utrecht, Rotterdam and The Hague, with multiple male and female guides available. You can review options and request a sitter via this page. Choose a guide based on experience, background and your preferences, not only on who has the […]

In the Netherlands, access to psilocybin depends on the form and its legal status. Magic truffles are legal to buy and possess, and are widely sold in smartshops and online. They contain the same active compounds as psilocybin mushrooms, and products vary in potency. Mushroom grow kits are legal to purchase, but once mushrooms grow, […]
