Microdosing means taking a tiny amount of a substance such as truffles, repeatedly over a period, small enough that you don't notice a clear change in perception. Research into what microdosing does is still young, and independent sources point out that expectation and placebo probably play an important role. It is something different from a guided truffle ceremony, such as the ceremonies Stars Frequencies offers in Amsterdam.
Microdosing is a practice in which people take a tiny amount of a substance, for instance truffles, at intervals over a longer period. The idea is that the amount stays below the point where you'd notice a clear shift in how you see or feel things. People go about their day as usual.
It became widely known over the past decade, partly through stories in the media and online. People mention reasons such as more focus, more creativity, a steadier mood or feeling more present. Those are reasons people give. They are not established effects.
This page explains what microdosing is. It doesn't give amounts, schedules or instructions, and it doesn't point to where anything can be obtained. If you're considering it, talk it through with someone who knows your situation, and with your doctor if you take medication.
Research is still at an early stage. Many reports come from people who try microdosing on their own initiative and fill in surveys afterwards. That makes it hard to separate the effect of the substance from the effect of expectation.
One of the larger placebo-controlled studies so far was published in 2021. 191 people who were already planning to try microdosing took part, and part of the time some of them took empty capsules without knowing it. Their wellbeing improved as well. The researchers suggest that positive expectations can explain much of what people report. The Jellinek summarises it in a similar way: it is not yet clear whether microdosing has real effects, and the placebo effect probably plays an important role.
That doesn't mean people's experiences are imagined. It means the evidence is thin, and honest information says so.
Independent sources also name possible risks. The Jellinek notes that microdosing could make existing psychological problems worse, such as anxiety, suspicion or manic phases in bipolar conditions, and that it is not advised if you have psychological problems. Medication matters as well: some combinations are not responsible, and you should never stop medication on your own.

In the Netherlands, truffles (sclerotia) are legal and fall outside the Opium Act. Mushrooms, the part of the fungus above ground and often called paddos, have been banned since 2008 and are on List II of the Opium Act. The Jellinek explains the legal picture in more detail, and our page on whether a truffle ceremony is legal covers the ceremony side.
Legal is not the same as risk-free, and not the same as suitable for everyone. Medication, psychosis or schizophrenia in yourself or a close family member, bipolar type I and other conditions are reasons to be careful, whatever the form.
Microdosing and a ceremony are sometimes mentioned in one breath, but they are different things. Microdosing is meant to stay in the background of an ordinary day. A truffle ceremony is one day set apart for it, with a noticeable experience, in a prepared space, with someone present the whole time.
| Microdosing | Truffle ceremony at Stars Frequencies | |
|---|---|---|
| Aim | Stay in daily life, barely noticeable | One day set apart, a noticeable experience |
| Time | Over a longer period | One day of about seven hours |
| Setting | Your own daily surroundings | A quiet space, a group of at most 8 or private |
| Guidance | Often alone | Rosa in the room for the whole ceremony |
| Screening | Depends on the person | Always, in a free 30-minute intro call |
| Research | Still thin, placebo probably plays a role | No promises about outcomes |
Which one fits isn't a question with one answer. Our comparison of microdosing and a ceremony goes through it side by side.
Rosa also offers microdosing guidance. It is a form of personal guidance, not a product. Ask her about it in an intro call, where you can talk through whether it fits you and what it looks like.
Stars Frequencies doesn't give amounts or schedules online. What fits depends on the person, on medication and on history, and that conversation belongs in a personal call, not on a web page.

That isn't clear yet. Placebo-controlled research suggests that expectations explain much of what people report, and independent sources such as the Jellinek describe the evidence as thin. People's experiences are real to them, but they are not proof of an effect.

Not for everyone. Independent sources note that it may make existing psychological problems worse and advise against it if you have them. If you take medication, talk to your doctor first, and never stop medication on your own.

Tell Rosa in the intro call if you are microdosing or thinking about it. She takes it into account when you look together at whether and when a ceremony fits.
Yes. Rosa also offers microdosing guidance as a form of personal guidance. Ask her about it in a free intro call, where you can talk through whether it fits you.
