Two Grams in Amsterdam
Psilocybin mushrooms are illegal in the Netherlands. Truffles are not. A first-person account of a weekend at a professional Amsterdam retreat center — what it costs, what it delivers, and whether it's worth the trip.
Psilocybin mushrooms are illegal in the Netherlands, but psilocybin truffles (sclerotia) exist in a legal gap that has produced a professional retreat industry in Amsterdam. I attended a weekend program at Synthesis. This is my honest account — including the cost, because I want to be real about the financial reality.
Synthesis operates at the professional end of the retreat spectrum. The preparation program spans several weeks online before you arrive. Facilitators are trained in a specific protocol. Pricing reflects the service level — approximately €1,500 for the weekend. I want to name that clearly because the range of retreat options internationally is enormous and cost is a real consideration for most people.
The preparation program was more substantive than I expected — not just administrative. Intention-setting, preparation practices, what to expect, integration frameworks. By the time I arrived in Amsterdam, I already had a clear sense of what I was bringing to the session.
The session itself was in a dedicated room with eight participants and four facilitators. Music was provided but participants could use headphones or not — I went without. The truffles came at a moderate dose, lower than what I might have taken on my own, which I appreciated for a first facilitated experience.
The experience over five hours was notable primarily for its gentleness. This surprised me — I had expected something more dramatic. Instead it was like a steady, quiet opening. More clarity than revelation. A particular moment stands out: looking at my hands and feeling, very directly and without drama, that I was here — that being here was enough — and that I had been complicating that simple fact for years.
The integration circle the following day, in a group with the other participants from different countries, was unexpectedly moving. Eight people, different lives — all having touched something similar from different angles.
I left Amsterdam having had a meaningful experience rather than a transformative one. Meaningful is underrated.
