WHAT IS a MICRODOSING protocol
A microdosing protocol is a structured schedule that outlines how, when, and how often a microdose is taken over a set period of time. Instead of taking microdoses randomly or intuitively, a protocol provides a consistent framework for dose size, timing, frequency, and rest days, making the experience more intentional, trackable, and sustainable.
The protocol you choose shapes everything: your tolerance trajectory, how visible the effects feel, your ability to observe and track changes, and your long-term sustainability. In other words, it doesn’t just organize your routine—it directly influences the quality and clarity of your experience over time.
There is no universally “best” microdosing protocol. However, there are better or worse starting points depending on your goals, lifestyle, sensitivity, and experience level. Some protocols are more structured and frequent, while others are more spaced out to prioritize integration, reflection, and minimizing tolerance buildup.
Most microdosing protocols are built around repeating cycles that include both “on” days (when a microdose is taken) and “off” days (when no dose is taken). These breaks are essential because they allow the nervous system to reset, help prevent tolerance, and make it easier to notice subtle shifts in mood, focus, creativity, and emotional regulation.
A complete microdosing protocol typically includes:
-
Dose amount (a consistent sub-perceptual level)
-
Timing (what time of day the dose is taken)
-
Frequency (how often dosing occurs)
-
Cycle structure (on/off day pattern)
-
Total duration (length of the protocol cycle)
-
Integration practices (journaling, reflection, lifestyle awareness)
This page breaks down the full landscape of microdosing protocols so you can understand how each one works and choose an approach that fits your body, goals, and daily life.

Why Your Protocol Choice Matters More Than Your Dose
Most beginner focus goes to dose selection — and while starting low matters, the schedule you follow is arguably more consequential for long-term outcomes. Protocols govern three things that dose alone cannot: tolerance management, baseline comparison, and integration time.
Tolerance builds faster than most people expect
Psilocybin builds tolerance rapidly — faster than almost any other psychoactive substance. Daily dosing produces near-complete tolerance within 3–4 days, which is why every structured protocol includes mandatory off days. A microdose on day seven of daily use may produce almost no effect, leading people to wrongly conclude the substance isn't working and escalate their dose. The off days aren't rest — they're pharmacologically essential.
Baseline days are your data
Off days serve a second function: they give you a comparison baseline. Without regular days when you haven't dosed, distinguishing the protocol's effects from placebo, seasonal mood variation, or life circumstances becomes nearly impossible. This matters for safety as much as for efficacy — warning signs are harder to catch when every day is a dose day.
Integration time is a feature, not a gap
The Fadiman Protocol's two off days weren't arbitrary — Dr. Fadiman's research indicated that many of the cognitive and emotional benefits continued to unfold on the day immediately after dosing. The off days are where much of the processing happens. Protocols that collapse this window tend to produce more side effects and less sustainable benefit.
Research note |
No randomized controlled trial has directly compared microdosing protocols head-to-head. The evidence base for protocol-specific outcomes is almost entirely self-report survey data and the clinical observations of researchers like James Fadiman and Paul Stamets. Protocol recommendations are therefore based on community consensus, harm reduction principles, and pharmacological reasoning — not clinical trial evidence.
Protocol 1: The Fadiman Protocol
Protocol 01
Fadiman Protocol
1 day on · 2 days off · repeat for 4–8 weeks
Beginner · Most Studied
Developed by psychedelic researcher Dr. James Fadiman based on self-report data from hundreds of microdosers collected over more than a decade. The Fadiman Protocol is the closest thing microdosing has to a clinical standard — it's the schedule used in most observational research, the one most healthcare providers familiar with microdosing will recognize, and the lowest-risk entry point for someone new to the practice.
The logic is precise: one dose day, followed by a transition day (day 2, when lingering effects and integration continue), followed by a baseline day (day 3, fully off). This creates a repeating three-day cycle regardless of where it falls in the calendar week.
Advantages
Most researched protocol — best evidence base
Built-in baseline days for clean self-monitoring
Generous recovery time minimizes side effect buildup
Two full off days before next dose prevents rapid tolerance
Easy to pause or adjust without disrupting the cycle
Widely recognized by psychedelic-informed clinicians
disAdvantages
Rolling 3-day cycle drifts through the calendar week
Only ~33% dose days may feel insufficient for some goals
Less suited for people seeking daily consistent mood support
Requires tracking — dose days shift every week
Best suited for
-
First-time microdosers
-
General wellbeing
-
Mood support
-
Anyone wanting the safest entry point
-
People on flexible schedules
Evidence note |
The Fadiman Protocol is the schedule used in most published microdosing observational research, including Polito & Stevenson (2019) and the Fadiman & Korb (2019) survey. It has the widest community and clinical familiarity of any protocol, which also means adverse effects and typical response patterns are better characterized here than for any other schedule.
Protocol 2: The "stamet's stack"
Protocol 02
stamet's stack
4 days on · 3 days off · psilocybin + Lion's Mane + niacin
Intermediate · Neuroplasticity focus
Developed and popularized by mycologist Paul Stamets, this protocol layers three substances: a psilocybin microdose, Lion's Mane mushroom (Hericium erinaceus), and niacin (vitamin B3). The hypothesis — which Stamets has described publicly but not yet published in peer-reviewed form — is that niacin acts as a "carrier" that flushes the psilocybin and Lion's Mane compounds into peripheral nervous system tissue, potentiating the neuroplasticity effects of both.
The four-days-on, three-days-off schedule was chosen to align more with the standard work week and to allow for weekend recovery. It's a more intensive protocol than Fadiman, and the compound nature of the stack makes it harder to attribute effects to any single component. Some follow a five-days-on, two-days-off schedule but for our purposes we will call that the "Weekday Protocol."
The stack components
Psilocybin: 0.05–0.1g dried mushrooms (standard microdose). Lion's Mane: 50–200mg extract or 500mg–1g whole mushroom powder. Lion's Mane independently promotes NGF (nerve growth factor) production and has its own cognitive support evidence base. Niacin: 50–100mg. Note: niacin at these doses causes a "flush" reaction — warmth, redness, tingling — in many people. This is not dangerous but is noticeable and worth knowing before your first dose. If this sensation is too uncomfortable, taking an anti-histamine may help this side effect.
Advantages
Aligns better with work week
Lion's Mane adds independent cognitive/neuroprotective benefit
Most discussed protocol for neuroplasticity goals
Calendar consistency — same days every week
disAdvantages
Niacin flush uncomfortable and off-putting for many
Higher dose frequency increases tolerance risk
Three-component stack makes effects hard to attribute
Core neuroplasticity hypothesis is unproven in human trials
Not appropriate for beginners — too many variables at once
More expensive than single-substance protocols
Best suited for
-
Experienced microdosers (1+ prior Fadiman cycles)
-
Neuroplasticity & learning goals
-
People who prefer calendar-fixed schedules
-
Those open to supplement stacking
Evidence status |
Stamets has described the theoretical basis for this stack in interviews and a patent application — not in peer-reviewed publications. The mechanism involving niacin as a peripheral carrier is plausible but undemonstrated in human research. Lion's Mane's neurotropic effects are better evidenced independently. The combined stack has not been tested in clinical trials.
Protocol 3: Every Other Day (Microdosing Institute Protocol)
Protocol 03
Every Other Day
Alternating dose / off days · 1–2 months · then 2–4 week break
Intermediate · Theraputic focus
Developed and promoted by the Microdosing Institute, this protocol was designed primarily for people seeking relief from conditions like anxiety, depression, cluster headaches, and migraines — applications where more frequent low-level serotonergic activity may be beneficial. The strict alternating structure (one day on, one day off) provides more frequent exposure than Fadiman while still maintaining mandatory off days to prevent tolerance collapse.
The protocol specifies a defined treatment period of 1–2 months followed by a mandatory 2–4 week break — a cycling structure that sets it apart from open-ended use. This built-in termination point is one of its strongest features from a harm reduction perspective.
Advantages
Higher frequency may better suit anxiety and mood conditions
Regularly cited for headache and migraine relief reports
Built-in cycling period with defined break — good harm reduction
Simple to follow: strictly alternating regardless of day
Maintains off-day baseline for comparison
disAdvantages
Higher tolerance accumulation risk than Fadiman
Only one recovery day between doses — less integration time
Not ideal for beginners — intensity before calibration is risky
Dose days don't align with calendar week
May amplify side effects in anxiety-prone individuals
Best suited for
-
Anxiety and depression symptom management
-
Cluster headache / migraine (with research)
-
Those wanting defined treatment periods
-
People comfortable with intermediate frequency
Migraine and cluster headache note |
The Every Other Day protocol has a specific following among people using psilocybin for cluster headaches and migraines — applications where there is community and some preliminary clinical support, separate from the general microdosing literature. The Clusterbusters organization has documented patient-reported outcomes for several years. This is a distinct use case from general wellness microdosing and warrants its own research review.
Protocol 4: Every Other Day (Microdosing Institute Protocol)
Protocol 04
Weekday Protocol
Monday–Friday dose · Saturday–Sunday off
Intermediate · Performance focus
A pragmatic, calendar-anchored schedule that aligns microdosing with the standard work week. Monday through Friday are dose days; weekends are off. The appeal is obvious: maximum consistency with professional and social life, and an easy-to-remember pattern that requires no tracking. The weekend off days also mean uninterrupted social and family time without the need to account for dose days.
The significant limitation is pharmacological: five consecutive dose days pushes against the tolerance ceiling rapidly. By Thursday or Friday of the first week, many people find effects are noticeably reduced. The two-day weekend break partially restores sensitivity, but this protocol operates closer to the edge of diminishing returns than any other structured schedule.
Advantages
Perfectly calendar-aligned — no tracking needed
Weekends fully clear for social and family life
Maximum dose-day frequency for work performance goals
Intuitive to maintain over months
disAdvantages
Highest tolerance accumulation of any scheduled protocol
Two weekend days insufficient to fully reset tolerance
Risk of emotional blunting and diminishing returns faster
Not recommended for beginners — no calibration phase
No baseline days during the week for self-monitoring
Dose escalation temptation as tolerance builds mid-week
Best suited for
-
Work-performance oriented users
-
People who value schedule simplicity above all
-
Experienced microdosers only
-
Those with clear weekday/weekend lifestyle separation
Tolerance Warning |
Five consecutive dose days will produce measurable tolerance buildup in most people. If you use this protocol, be alert to dose escalation temptation — the feeling that the microdose "isn't working" by Thursday is a tolerance signal, not a sign to increase the dose. Reducing to Mon/Wed/Fri within the same calendar framework is a common and effective modification.
Protocol 5: The Nighttime Protocol
Protocol 05
nighttime Protocol
Evening / bedtime dose · layered onto any base schedule
Intermediate · Sleep & Anxiety focus
The Nighttime Protocol is less a standalone schedule and more a dosing-time modification that can be layered onto any base protocol. Instead of taking the microdose in the morning, the dose is taken in the evening — typically 1–2 hours before bed. The goal is to sidestep daytime functional effects entirely, allowing integration to happen during sleep, and to access potential benefits for sleep quality, anxiety reduction, and emotional processing without any disruption to daytime performance.
This protocol has grown in discussion particularly among people who found daytime microdosing too stimulating, those in roles where any cognitive alteration — however subtle — is unacceptable, and people whose primary goals involve sleep quality or nighttime anxiety rather than daytime focus.
What happens during a nighttime dose
At true microdose levels, most people report no disruption to sleep onset — some report improved sleep quality and more vivid but not distressing dreams. The sub-perceptual effects that might be felt as mild stimulation during waking hours are largely unnoticed during sleep. Some people report a sense of emotional clarity or lighter mood upon waking on the morning after a nighttime dose.
Advantages
Zero impact on daytime professional functioning
Suits anxiety and sleep-focused goals specifically
Processing and integration during sleep may deepen effects
Eliminates dose-day scheduling concerns for work
Dream content can serve as integration material
disAdvantages
Sleep disruption possible if dose is too high
Harder to track daytime effects — less observable data
Limited community data compared to morning dosing
Not appropriate for anyone with sleep disorders without guidance
Morning-after effects may cause grogginess at higher doses
Best suited for
-
Anxiety and stress with sleep impact
-
Professionals where daytime clarity is non-negotiable
-
People who found morning microdosing too stimulating
-
Those interested in dream and sleep integration
-
Parents with morning obligations
-
Those naturally sleepy interacting with psilocybin
Recommended Base Schedule |
The Nighttime Protocol works best layered onto the Fadiman 1-on-2-off structure, applied at night. Start at the lower end of the microdose range (0.05g) specifically for nighttime use — the absence of daytime reference points makes it harder to calibrate if you've started too high. Track sleep quality, morning mood, and any dream content in your journal.
Protocol 6: Intuitive Dosing
Protocol 06
Intuitive Dosing
As-needed · experience and body-signal guided
Advanced only · High self-knowledge required
Intuitive dosing abandons fixed schedules entirely in favor of dosing when the practitioner feels called to, based on accumulated self-knowledge about their body's signals, current life circumstances, and intentions. It is not random — experienced intuitive dosers describe a discernible internal signal, a kind of readiness or receptivity, that guides their timing. But it requires significant prior experience to distinguish genuine body-signal from rationalization or habit.
This approach is occasionally described in the microdosing literature and is practiced by some long-term users who have built deep familiarity with their responses over 1–2+ years of structured protocol use. It is not a starting point and should not be treated as one.
Advantages
Maximally personalized — responds to actual needs
Prevents protocol-induced rigidity or compulsion
Natural tolerance management through felt sense
Integrates microdosing as a mindful practice
disAdvantages
Requires 1–2+ years of prior structured experience
Self-deception and rationalization risk is high
Impossible to track or evaluate systematically
No external structure to prevent unconscious dose escalation
Not appropriate if microdosing for specific therapeutic goals
Best suited for
-
Experienced microdosers (1+ years structured use)
-
People with established mindfulness practice
-
Maintenance phase after achieving primary goals
-
Not recommended for most
Not for beginners — seriously |
This is mentioned repeatedly throughout our guides because the temptation to start here is real: "I'll just dose when it feels right" sounds sensible and is almost always a mistake in practice. Without baseline experience of how your system responds, you have no internal calibration to draw on. The body signals that experienced intuitive dosers describe develop only after sustained, structured practice. Start with Fadiman. Come back to this after a year.

Cycling and Breaks: Guidance for Each Protocol
Every protocol requires structured breaks. The length of on-cycle and the appropriate break period vary by schedule intensity. These are minimum recommendations — taking longer breaks is always appropriate and sometimes valuable.
FADIMAN
4–8 weeks on
2–4 weeks fully off
EVERY OTHER DAY
1–2 months on
2–4 weeks off
NIGHT TIME
Follow base protocol
Same as base protocol
STAMETS
4 weeks on
2–4 weeks off (higher intensity)
WEEKDAY
4–6 weeks on
2 weeks minimum off
INTUITIVE
Self-monitored
Minimum 2–4 wks/quarter
Signs you need a break sooner |
Regardless of where you are in a cycle, take a break if you notice: dose days feeling indistinguishable from off days (tolerance saturation), emotional blunting or flatness emerging, increasing desire to dose more frequently, or any warning sign from our risks guide. These signals mean the break is needed now, not at the scheduled end of the cycle.
frequently asked questions
Which microdosing protocol is best for beginners?
The Fadiman Protocol (1 day on, 2 days off) is universally recommended for beginners. It has the best evidence base, the most generous recovery time between doses, mandatory baseline days for tracking, and is the most forgiving if your initial dose is slightly off. Complete at least one full 4–6 week Fadiman cycle before considering any other protocol.
Is the Stamets Stack better than the Fadiman Protocol?
Not better — different. The Stamets Stack is more intensive, adds Lion's Mane and niacin, and is primarily positioned for neuroplasticity goals. It has a higher tolerance accumulation risk and the core mechanism is unproven in peer-reviewed research. Fadiman has a stronger evidence base, lower risk, and is better suited to general wellbeing, mood, and beginners. The Stamets Stack is worth considering after you've established your response with Fadiman — not before.
What is the Every Other Day protocol used for?
Developed by the Microdosing Institute, the Every Other Day protocol (alternating dose/off days for 1–2 months before a break) is most commonly used for anxiety, depression, and headache/migraine relief. The higher frequency compared to Fadiman may better support persistent mood conditions. It includes a built-in cycling structure with a mandatory break, which is one of its strongest harm reduction features.
Can I microdose at night instead of in the morning?
Yes — the Nighttime Protocol involves taking your microdose 1–2 hours before bed rather than in the morning. It's particularly well-suited for people whose primary goals involve anxiety reduction, sleep improvement, or avoiding any daytime effect. Most people at true microdose levels report no significant sleep disruption. Start at the lower end of the dose range and layer this approach onto a Fadiman-style schedule for the safest introduction.
Why do all protocols have off days?
Off days serve two essential functions. Pharmacologically, psilocybin builds tolerance very rapidly — continuous daily dosing produces near-complete tolerance within 3–4 days, making the substance effectively inactive. Off days allow partial receptor sensitivity restoration. Practically, off days provide a baseline comparison: without them, you can't distinguish the protocol's effects from placebo, seasonal mood variation, or life circumstances. Both functions are necessary for safe, effective microdosing.
Can I switch protocols mid-cycle?
You can, but it's better practice to complete a cycle, take a break, and then start the new protocol fresh. Switching mid-cycle makes it nearly impossible to attribute observed effects or problems to the protocol change vs the substance itself. If you're experiencing side effects that require a schedule change, pause the cycle, take a break, and restart with your adjusted approach after tolerance has reset.
What protocol works best for cluster headaches?
The Every Other Day protocol is most commonly cited in cluster headache and migraine communities, where more consistent serotonergic activity may help interrupt pain cycles. The Clusterbusters organization has documented patient-reported protocols specifically for this use. Note that headache and migraine applications of psilocybin have a distinct evidence base from general wellbeing microdosing — research the headache-specific literature separately and ideally work with a neurologist familiar with this area.
