Microdosing Guide

substances LSD · psilocybin
goal sub-perceptual dose
evidence preliminary

Microdosing means taking doses small enough that you don't trip, but large enough for subtle effects on mood, focus, or creativity. The science is early — most evidence comes from community reports rather than clinical trials.

dose thresholds — what each level does

levelmushrooms (dried)LSDeffect
sub-perceptual0.05–0.15g5–15µgNo noticeable effects. Subtle background shift.
threshold0.15–0.3g15–25µgBarely noticeable. Slight mood or focus lift.
mini-dose0.3–0.5g25–40µgClearly perceptual. Some visuals. Not a full trip.
low dose0.5–1g40–75µgNoticeable trip. Free day recommended.

unit conversion — critical

protocols

Fadiman Protocol
Day 1: dose · Day 2: rest · Day 3: rest · repeat
The most widely used protocol. Every third day allows tolerance to reset and avoids buildup effects. Originally developed by James Fadiman through self-report studies.
Stamets Protocol
5 days on · 2 days off · repeat
Developed by Paul Stamets. Often combined with lion's mane mushroom and niacin (the "Stamets Stack"). More frequent dosing — some find it too stimulating.
Intuitive / As-Needed
Dose when needed, with minimum 2 rest days between
Less structured. Better for experienced microdosers who know their response. Harder to track and assess effects systematically.
