The Fadiman Protocol: How to Microdose Safely
The most widely used microdosing schedule in the world — simple, effective, and designed to prevent tolerance from building while giving you structure to track results.
Who is James Fadiman?
An American psychologist and researcher who has studied psychedelics since the 1960s. Fadiman developed his microdosing protocol based on data collected from hundreds of self-reporting participants across multiple years. His book The Psychedelic Explorer's Guide remains a key reference in the field.
The Protocol
Day 1
Microdose
Day 2
Rest
Day 3
Rest
Day 4
Microdose
Day 5
Rest
Day 6
Rest
Day 7
Microdose
...and so on for 4–8 weeks
One dose every three days. Two rest days between each dose.
Why Three Days? Why Not Every Day?
Tolerance
Psilocybin builds tolerance quickly. If you take it on consecutive days, you need a higher dose to feel the same effect by day three. The rest days reset your sensitivity, keeping each microdose effective throughout the protocol.
The afterglow (Day 2)
Day 2 — the day after a microdose — is often described as the most productive day of the cycle. The effects carry over subtly: clearer thinking, better mood, slightly enhanced creativity. Rest days aren't empty — they're part of how the protocol works.
Observation (Day 3)
Day 3 is your clearest baseline — no active dose, no afterglow. Comparing how you feel on day 3 vs. day 1 helps you assess whether the protocol is having any effect at all.
What Dose to Use
For fresh magic truffles — the most practical format for microdosing.
| Dose | |
|---|---|
| Starting dose | 0.5g fresh truffle |
| Standard microdose | 0.5–1g fresh truffle |
| Upper limit | 1.5g (beyond this, effects become noticeable) |
Start at 0.5g for your first cycle. If you feel nothing over 2–3 weeks, increase to 1g. If you feel clearly altered, reduce the dose. The goal is sub-perceptual — you should be able to go about your normal day without anyone knowing you've taken anything.
How to Track Progress
Track daily
Before you start: record a week of baseline entries without microdosing. This gives you something real to compare against. What to look for: not dramatic changes on individual days — patterns over weeks. Fewer low-mood days, more productive mornings, less reactivity to stress.
Duration and Breaks
Protocol length
4–8 weeks is the standard Fadiman recommendation. Long enough to establish patterns; short enough to avoid habituation.
After the protocol
Take a break of at least 2–4 weeks before starting another cycle. Restores full sensitivity and gives time to integrate what you noticed.

Microdosing has gone from fringe practice to mainstream conversation in a short time. But the information around it ranges from rigorous to wildly exaggerated. This guide gives you a practical, honest foundation.
What Is Microdosing?
Microdosing means taking a very small dose of a psychedelic substance — typically one-tenth to one-twentieth of a full dose — on a regular schedule. The goal is sub-perceptual effects: small enough that you don't feel clearly "high," but potentially enough to notice subtle shifts in how you think, feel, or work.
Typical microdose with psilocybin
0.5–1g
Fresh magic truffles
0.1–0.3g
Dried psilocybin mushrooms
What the Research Actually Says
What research suggests
- ✓Improved mood and reduced symptoms of depression and anxiety in microdosing populations
- ✓Increased creativity, open-mindedness, and flow states in some participants
- ✓Growing body of observational and self-report data supporting real effects
What research doesn't confirm
- →Most studies are observational — not controlled trials
- →Placebo effects are significant and difficult to control for
- →Individual responses vary enormously — some report no benefit or negative effects
The honest position: microdosing works well for many people, isn't a cure-all, and the science is still catching up with the practice. Go in with realistic expectations, not miracle claims.
How to Start
Get the right product
The most practical format for beginners is fresh magic truffles — they come in measured doses, are legal in the Netherlands, and have consistent potency that makes it easy to establish a reliable microdose.
Choose a protocol
A protocol is a schedule for when you take a microdose and when you rest. The most widely used is the Fadiman Protocol — one day on, two days off, repeated over 4–8 weeks. → The Fadiman Protocol Explained
Set a baseline
Before you start, spend a week tracking your mood, sleep, energy, and focus without microdosing. A simple daily note is enough. This baseline helps you notice whether anything actually changes once you begin.
Start low
Begin at 0.5g fresh truffle. You can always increase slightly after a few cycles if you feel nothing. Starting too high risks effects becoming noticeable in ways that interfere with your day.
Track and adjust
Keep a brief daily journal during your microdosing period. Note how you feel on dose days vs. rest days. Look for patterns over weeks, not days.
What to Expect
On dose days
Most people feel little or nothing at a proper microdose. Some report a subtle lift in mood, slightly increased focus, or a sense of being more present. If you feel clearly altered, your dose is too high.
On rest days
Rest days are where many people notice the effects most clearly. A slightly better mood, more patience, more creative thinking. The contrast between dose and rest days can be informative.
Over weeks
Look for patterns — fewer low-mood days, more productive weeks, easier emotional regulation. Not dramatic day-to-day shifts.
If nothing happens
This is common and normal. Try for a full 4-week protocol before concluding it doesn't work for you.
What microdosing is not
- ✗A substitute for therapy, medication, or professional support for serious mental health conditions
- ✗A productivity hack with guaranteed results
- ✗Risk-free — some people experience increased anxiety or disrupted sleep at doses too high
- ✗Legal everywhere in Europe — verify the legal status in your country
