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.
