LSD mainly activates serotonin 5-HT2A receptors in the cortex. This shifts how cortical pyramidal cells fire and boosts glutamate signaling, loosening the brain’s usual filtering of signals. It also interacts with other receptors that may add subtle changes in arousal and mood. For a compact explainer of how it works, see this Q&A. At the […]

Short answer: possibly, but only in a subjective sense. The “problem box” is a helpful metaphor for how attention seeks things to work on; it is not a defined brain structure I can verify. In carefully supported contexts, some people report that psychedelics loosen rigid thought patterns and make it easier to notice when the […]

Yes, a truffle ceremony after ayahuasca is possible. The more important question is whether you have had enough time to integrate your previous experience. Many people choose to wait several weeks, sometimes a month or two, to reflect, stabilize, and integrate insights before considering another session. There is no universal interval I can verify, and […]

You can arrange a duo guided psilocybin truffle session in Rotterdam from England with a few simple steps. Plan your trip to Rotterdam The Hague Airport, book accommodation in the city, and choose a date. Request a duo session with an on-location facilitator in Rotterdam, complete their intake and consent, and prepare two quiet rooms […]

Before the festival, agree on clear boundaries, a simple plan, and consent: what they might take, no impulsive mixing or redosing, a code word for time out, preferred stages and triggers to avoid, and your authority to end the night if safety is at risk. Share locations for exits, first aid, chill spaces, and a […]

Yes. Starting indoors is often the wiser choice because the first phase can be unpredictable. A calm room with a bathroom, shade, a place to lie down, and minimal noise helps you settle before deciding whether a beach setting feels right. If possible, pick an indoor base close to the beach so you can step […]

Yes, that swing from intense shame to a sense of no shame can happen in high-dose truffle ceremonies. Strong experiences often loosen habitual self-judgment for a while, which can reveal both the weight of shame and what it feels like when it drops away. For some, moving between these poles helps them notice core beliefs […]

There is no universal “better” choice, but for therapy MDMA is generally the better-supported option because it has the most clinical research and a more predictable profile. 5-MAPB has far less study data, variable sourcing, and unknown long-term risks, so it is more experimental. Subjectively, many describe MDMA as pro-social and talk-friendly, while some report […]

Short answer: you cannot legally receive MDMA from a therapist or guide in Amsterdam, and possession of MDMA is illegal in the Netherlands. Reports suggest that from July 1, 2025, many providers only offer guidance and integration and cannot supply MDMA or MDMA analogs. Some may offer harm-reduction style sitting, but that does not change […]

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 […]

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 […]

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 […]
