Microdosing refers to taking psilocybin at doses low enough that no perceptual effects occur. There are no visuals, no altered sense of time, and no disruption to normal functioning. The goal is subtler: a mild shift in mood, cognition, or emotional tone that accumulates over weeks of consistent practice.
Interest in microdosing has grown considerably over the past several years, driven partly by anecdotal reports from professionals in creative and knowledge-work fields, and more recently by a growing body of observational and clinical research. This guide covers the main protocols in use, how to structure a starting approach, and what to realistically expect.
What Counts as a Microdose
A microdose is generally defined as 5 to 10 percent of a standard psychoactive dose. For dried psilocybin mushrooms, a common macrodose sits between 2 and 3.5 grams. A microdose therefore falls roughly between 0.05 and 0.3 grams, with most people finding their effective range between 0.1 and 0.2 grams of dried mushroom.
In capsule form, this typically translates to doses between 50 mg and 200 mg of mushroom content per capsule. The advantage of capsules is consistency: the same dose every time, without the need to weigh powder or split dried material.
If you feel any perceptual change after taking a microdose, the dose is too high. Adjust downward until the dose is genuinely sub-perceptual before beginning a protocol.
The Main Microdosing Protocols
Several structured schedules have emerged from community practice and researcher James Fadiman’s early surveys of self-reported microdosers. Each has a different rhythm of dosing and rest days, built around the principle that tolerance accumulates quickly with psilocybin and rest days are necessary to maintain sensitivity.
The Fadiman Protocol
This is the most widely used starting protocol. The schedule is one day on, two days off, repeated over four to eight weeks.
- Day 1: dose day
- Day 2: transition day (no dose; some people notice carry-over effects)
- Day 3: rest day (no dose)
- Day 4: dose day again
The two rest days between doses prevent tolerance from building while allowing enough time between sessions to observe the pattern of effects. Most people following the Fadiman protocol dose two to three times per week.
Fadiman recommends keeping a daily journal to track mood, energy, focus, sleep, and social ease, on both dose and non-dose days. The off days are as informative as the on days when assessing whether the protocol is working.
The Stamets Stack
Developed by mycologist Paul Stamets, this protocol combines psilocybin with lion’s mane mushroom and niacin (vitamin B3). The proposed mechanism is that lion’s mane supports neurogenesis and niacin acts as a flushing agent to drive the compounds into peripheral tissues.
The schedule is five days on, two days off. Doses of psilocybin in this stack are typically at the lower end of the microdose range, around 0.1 grams, combined with 500 to 1000 mg of lion’s mane and 100 to 200 mg of niacin.
The niacin flush, a temporary sensation of warmth and tingling, can be uncomfortable for some people. Starting with a lower niacin dose and building gradually helps manage this. The Stamets Stack has a dedicated following, particularly among people focused on neuroplasticity and cognitive performance, though controlled research on this specific combination remains limited.
Every Other Day
A simpler schedule than the Fadiman protocol: dose every second day, rest every second day. This works out to dosing roughly three to four times per week. Some people prefer this rhythm because it is easier to track without needing to count a specific pattern of on and off days.
The every-other-day schedule carries a slightly higher risk of tolerance accumulation than the Fadiman protocol over longer periods. It works best for shorter protocol windows of four to six weeks, followed by a full break.
Intuitive Microdosing
Some experienced microdosers move away from fixed schedules after completing one or two structured protocols. They dose when they feel it would be useful, typically once or twice a week, using their accumulated self-knowledge to guide timing rather than a calendar.
This approach is not recommended for beginners. Without a baseline of experience with how psilocybin affects you at a microdose level, intuitive dosing makes it difficult to distinguish the compound’s effects from ordinary mood variation.

How Long to Run a Protocol
Most practitioners recommend an initial protocol of four to eight weeks, followed by a rest period of two to four weeks with no dosing. This break allows the nervous system to return to baseline and gives you a cleaner comparison point for assessing whether the protocol produced meaningful changes.
After the rest period, you can choose to run another protocol, adjust your dose or schedule, or discontinue based on what you observed. Many people find that two or three protocol cycles per year is sufficient for their purposes.
What to Track
Journaling is not optional if you want to assess whether microdosing is working for you. The subjective nature of the effects makes it easy to either over-attribute improvements to the protocol or dismiss genuine changes as coincidence. A daily log, even a brief one, provides a more reliable picture over time.
Useful dimensions to track include mood and emotional tone, energy levels throughout the day, quality of focus and cognitive ease, sleep quality and dreams, social comfort and interpersonal ease, and any side effects such as increased anxiety, irritability, or difficulty sleeping. Track all of these on dose days, transition days, and rest days. The pattern across the full week is more informative than any single day’s data.
Common Side Effects and How to Manage Them
Microdosing is generally well-tolerated, but side effects do occur, particularly when the dose is too high or the schedule is too frequent. The most commonly reported issues are increased anxiety or irritability, difficulty sleeping if dosed too late in the day, mild headaches, and occasional feelings of emotional intensity that fall short of a full psychedelic effect but are still noticeable. Most of these resolve by reducing the dose or adjusting the schedule.
Dosing in the morning, before 10 am where possible, reduces sleep interference. If anxiety increases noticeably on dose days, reducing the dose by 25 to 50 percent is usually more effective than switching protocols.
Choosing a Format
Dried mushrooms can be used for microdosing, but they require a reliable milligram-accurate scale and some consistency in how you prepare your doses. Potency varies between batches, which makes precise replication difficult.
Capsules address most of these challenges. A capsule with a fixed dose of mushroom powder removes the weighing step and provides consistent dosing across an entire protocol. For people new to microdosing, capsules are the format most likely to produce reliable, trackable results.
Canadians exploring microdose options can find a range of microdose capsules in varying strengths, from entry-level 50 mg formulations up to higher-concentration options suited to people with some prior experience.
Who Microdoses and Why
Survey data from James Fadiman’s research and subsequent academic studies suggests that the most common reasons people begin microdosing are depression and anxiety, followed by a desire to improve focus or cognitive performance, and then general curiosity or personal growth. Creative professionals, entrepreneurs, and people in demanding cognitive roles are overrepresented in self-reported microdosing communities.
People considering microdosing for anxiety specifically may find it useful to review what the research shows about low-dose psilocybin and the nervous system before beginning. The evidence is promising but still developing, and realistic expectations make for a more useful protocol than hope alone.
Sourcing and Access in Canada
Consistency of supply matters for microdosing in a way it does not for occasional macrodose use. Running out mid-protocol and switching products introduces variables that make it harder to assess results. Before starting, confirm you have enough product to complete the full protocol window.
Those in the GTA can access dried mushrooms and capsule products through online dispensaries offering shroom delivery in Aurora and across the broader York Region. For those further afield, mail order options ship across most Canadian provinces.
When sourcing for microdosing, prioritize products with clearly labelled doses and consistent batch quality over novelty or variety. The goal is repeatability, not range.
Final Thoughts
Microdosing works best when approached with structure, patience, and honest self-observation. The effects are subtle by design, and the protocol only yields useful information if you are paying attention carefully enough to notice them.
Start with a well-documented schedule, keep a daily journal, begin at a lower dose than you think is necessary, and give the protocol the full four to eight weeks before drawing conclusions. The people who report the most meaningful results from microdosing are almost always the ones who approached it as a practice rather than a shortcut.
Frequently Asked Questions
Can I microdose while working or driving?
A true microdose should not impair cognitive function or perception. That said, until you know how a specific dose affects you personally, it is sensible to try your first one or two doses on a day without professional obligations or driving requirements. Once you have confirmed the dose is genuinely sub-perceptual, normal daily activities should not be affected.
How long before I notice any effects from microdosing?
Most people do not notice significant changes in the first week. Effects, when they occur, tend to become apparent in weeks two to four as patterns emerge across dose and non-dose days. Expecting dramatic immediate results is one of the most common reasons people abandon a protocol too early.
Should I take a break from my current medications before microdosing?
No. Do not stop or adjust prescribed medications without consulting your doctor. SSRIs and SNRIs can reduce the sensitivity to psilocybin at microdose levels, which may mean a higher dose is required for effects, but discontinuing psychiatric medication without medical guidance carries its own risks that outweigh any benefit from improved psilocybin response.
Is there a risk of developing a dependency on microdosing?
Psilocybin does not produce physical dependence, and psychological dependency on microdosing is considered low risk. The rapid tolerance that builds with psilocybin actually makes compulsive daily use self-limiting. That said, structured protocols with built-in rest periods are better practice than open-ended continuous use, both for maintaining sensitivity and for honest assessment of whether the practice is still serving you.
