Legal Notice
Psilocybin is a controlled substance in most countries. Microdosing with psilocybin truffles is only legal in the Netherlands, where they can be purchased from licensed smart shops. This guide is for informational and educational purposes only. Always check and comply with your local laws.
Microdosing Guide 2026
The science, protocols, and practical guide to psilocybin microdosing — sub-perceptual doses for cognitive enhancement, emotional well-being, and creative flow.
What Is Microdosing?
Microdosing is the practice of consuming very small, sub-perceptual amounts of a psychedelic substance — typically psilocybin (from mushrooms or truffles) or LSD — on a regular schedule. The doses are far too small to produce hallucinations, visual distortions, or a "trip." Instead, users report subtle improvements in mood, focus, creativity, and emotional resilience.
The modern microdosing movement was catalyzed by Dr. James Fadiman's 2011 book The Psychedelic Explorer's Guide, though indigenous cultures have used sub-threshold doses of plant medicines for centuries. Silicon Valley tech workers brought microdosing into mainstream awareness around 2015, and since then interest has exploded globally.
A typical psilocybin microdose is 0.5–1.5 grams of fresh magic truffles or 0.05–0.15 grams of dried mushrooms — roughly 1/10th to 1/20th of a full dose. The threshold principle is simple: if you can clearly feel psychedelic effects, you've taken too much for a microdose.

Microdosing Protocols
📅 The Fadiman Protocol
Dr. James Fadiman — Most Popular
Follow for 4–8 weeks, then take 2–4 weeks off. The rest days prevent tolerance and allow baseline comparison. Keep a daily journal rating mood, energy, focus, and creativity on a 1–10 scale.
🍄 The Stamets Protocol
Paul Stamets — Stacking Approach
Stamets' "stacking" protocol adds Lion's Mane (for NGF stimulation) and niacin (vitamin B3, for vasodilation to push compounds to nerve endings). The theory: psilocybin creates new neural connections, Lion's Mane supports their growth, and niacin carries both to peripheral nerves.
Follow for 4 weeks on, 2 weeks off. The niacin flush (harmless skin flushing) is expected at 100–200mg.
🔄 Every-Other-Day Protocol
Simple alternative
Some practitioners prefer a simpler approach: microdose every other day (Mon/Wed/Fri/Sun, etc.). This provides more frequent dosing than Fadiman but still prevents tolerance. Less studied but widely used. Best for those who find the 3-day Fadiman cycle too infrequent.
🔮 Magic Truffles for Microdosing
The Netherlands is the only country where psilocybin microdosing is fully legal, thanks to the legal status of magic truffles (psilocybin-containing sclerotia). Dutch smart shops sell pre-packaged microdosing kits with precisely portioned truffle doses — making the Netherlands the global hub for legal microdosing.
Popular microdosing truffle varieties include Mexicana (mild, consistent, ideal for beginners) and Tampanensis ("Philosopher's Stone," slightly more introspective). Most Dutch smart shops sell microdosing strips with 6 pre-portioned doses of 1 gram each.
A typical truffle microdose is 0.5–1.5 grams of fresh truffles. Start at the low end and adjust. Truffles are more consistent in potency than wild mushrooms, making them ideal for precise microdosing. Store unused truffles in the refrigerator (2–4°C) for up to 2 months.
🔬 Scientific Research
Microdosing research is rapidly evolving. Here are the key studies and institutions driving the science:
Key Studies
- Imperial College London (2021) — Self-blinding microdose study with 191 participants. Found improvements in psychological well-being but noted placebo effects were also significant. Concluded that expectation plays a role but doesn't fully explain benefits.
- University of British Columbia (2022) — Observational study of 953 microdosers vs 180 non-microdosers. Microdosers reported improvements in mood, mental health, and psychomotor performance, with particularly strong effects in those over 55.
- Maastricht University (2023) — Controlled lab study found that a microdose of psilocybin truffles (0.5g) improved creative divergent thinking and emotional empathy without affecting convergent thinking.
Research Institutions
- Johns Hopkins Center for Psychedelic & Consciousness Research — Leading the FDA breakthrough therapy-designated psilocybin trials for major depression. Ongoing microdosing studies.
- Imperial College London — Centre for Psychedelic Research — Pioneered brain imaging studies showing how psilocybin increases neural connectivity and "resets" default mode network patterns.
- Beckley Foundation — Funding microdosing research globally, including studies on microdosing for ADHD, depression, and cognitive aging.
⚠️ Safety Considerations
Who Should NOT Microdose
- • Individuals with a personal or family history of psychotic disorders (schizophrenia, bipolar I)
- • People taking lithium (dangerous interaction with psychedelics)
- • Those on SSRIs or SNRIs (reduced effects and potential serotonin complications)
- • Pregnant or breastfeeding individuals
- • Anyone under 18 years old
- • People with color blindness concerns (some report visual snow at higher microdoses)
Best Practices
- • Start very low — 0.5g fresh truffles for your first attempt
- • First dose on a day off — don't microdose at work until you know your response
- • Keep a journal — track dose, time, mood, sleep, productivity daily
- • Cycle on and off — follow a protocol, don't dose daily
- • Don't drive on microdose days until you're sure of your response
- • Take breaks — 2–4 weeks off after every 4–8 week cycle

Frequently Asked Questions
What is a microdose of psilocybin?
A microdose is typically 1/10th to 1/20th of a full psychedelic dose — roughly 0.5 to 1.5 grams of fresh magic truffles, or 0.05 to 0.15 grams of dried psilocybin mushrooms. The defining characteristic is that the dose is sub-perceptual: you should not experience any visual distortions, significant mood shifts, or impairment. If you're 'tripping,' the dose is too high.
What is the Fadiman protocol for microdosing?
The Fadiman protocol, developed by Dr. James Fadiman, follows a 3-day cycle: Day 1 — microdose day, Day 2 — transition day (no dose, residual effects), Day 3 — normal day (no dose, baseline). Then repeat. This schedule prevents tolerance buildup and allows clear comparison between dose and non-dose days. Fadiman recommends keeping a journal to track effects.
Is microdosing legal?
Psilocybin is a controlled substance in most countries, making microdosing illegal in most jurisdictions. The notable exception is the Netherlands, where psilocybin-containing magic truffles are legal and sold in licensed smart shops — making it one of the few places where microdosing with truffles is fully legal. Some US cities have decriminalized psilocybin possession, but it remains federally illegal.
What does the scientific research say about microdosing?
Research is promising but still early. A 2022 study at the University of British Columbia found microdosers reported improved mood and focus compared to non-microdosers. Imperial College London's 2021 self-blinding study showed improvements in psychological well-being but could not rule out placebo effects. Johns Hopkins and NYU are conducting controlled trials. The scientific consensus: anecdotal reports are compelling, but rigorous placebo-controlled evidence is still being gathered.
