How to Microdose Mushrooms — The Complete Psilocybin Microdosing Guide
Microdosing psilocybin means taking a sub-perceptual dose of magic mushrooms — typically 0.05–0.25g dried — to support mood, focus, creativity, and well-being without tripping. Use our free protocol tool to get a personalised schedule adjusted for your mushroom species, goals, and experience level.
What is psilocybin microdosing?
Microdosing is the practice of taking 1/10th to 1/20th of a psychedelic dose on a repeated schedule. The goal is not to trip or hallucinate, but to achieve subtle therapeutic benefits — a slight mood lift, sharper focus, reduced anxiety — below the threshold of conscious perception.
If you “feel high,” the dose is too high. The ideal microdose is something you almost forget you took.

Microdosing psilocybin — therapeutic applications backed by science
Research from Johns Hopkins, Imperial College London, and NYU has positioned psilocybin as one of the most promising compounds in modern psychiatry. Here’s what the evidence says about microdosing for specific conditions.
Depression
Full-dose psilocybin therapy shows a 71% response rate for major depression (Davis et al. 2021, JAMA Psychiatry). For microdosing specifically, Polito & Stevenson (2019) found decreased depression scores over 6 weeks, and Rootman et al. (2021, N=8,703) found microdosers reported significantly lower depression than non-microdosers.
Anxiety & PTSD
Griffiths et al. (2016, Johns Hopkins) showed 80% of cancer patients had clinically significant anxiety reduction from psilocybin, sustained at 6 months. For PTSD, veteran-focused organisations like Heroic Hearts Project report meaningful results, though dedicated RCTs are still emerging.
Cluster Headaches & Migraines
One of the most compelling applications. Sewell et al. (2006, Neurology) found 25 of 48 psilocybin users reported cluster period termination. Schindler et al. (2021, Neurotherapeutics) showed a single low dose reduced migraine frequency by ~50%. Many sufferers report relief at sub-hallucinogenic (microdose) levels.
Focus, Creativity & Well-Being
Prochazkova et al. (2018) found microdosing increased both convergent and divergent thinking. Anderson et al. (2019, N=278) reported improved mood (26.6%), focus (14.8%), and creativity (12.9%) as the top benefits. Hutten et al. (2020, N=4,050) found performance enhancement was the #1 motivation for microdosing.
Addiction
Johnson et al. (2014, Johns Hopkins) showed 80% smoking abstinence at 6 months with psilocybin therapy — vs ~30% for best pharmacotherapy. Bogenschutz et al. (2022, JAMA Psychiatry) found 83% reduction in heavy drinking days. Microdosing-specific addiction evidence is survey-based but growing.
OCD
Moreno et al. (2006) found all 9 participants showed 23–100% decrease in OCD symptoms (YBOCS scores). Psilocybin’s action on 5-HT2A receptors is relevant because serotonergic dysfunction is implicated in OCD. Further trials are underway.
These results are primarily from full-dose clinical trials. Microdosing evidence is growing but less controlled. Individual responses vary significantly.
Psilocybin microdose calculator — personalised for your species and goals
Select your mushroom species, experience level, goal, protocol, and consumption form. The tool adjusts doses for strain potency (Penis Envy is 1.5–2x stronger than standard cubensis) and returns a complete protocol with schedule, monthly supply estimate, and safety notes.
How to use your protocol: Start at the lower end of the dose range. Stay there for 2–3 sessions. If you feel nothing, increase by 0.02–0.03g. If you notice perceptual changes, reduce immediately. Your ideal microdose is the lowest amount that produces a subtle, positive shift.
How much shrooms for a microdose? It depends on the species.
Psilocybin content varies dramatically between mushroom species. A 0.15g dose of Penis Envy is NOT the same as 0.15g of Golden Teacher. Always adjust for potency.
| Species / Strain | Potency | Low Microdose | Standard | High Microdose |
|---|---|---|---|---|
| Golden Teacher / B+ | 1.0x (baseline) | 0.05g | 0.10–0.15g | 0.20–0.25g |
| Penis Envy (PE, APE) | 1.5–2.0x | 0.03g | 0.05–0.08g | 0.10–0.15g |
| Liberty Cap | 1.2–1.7x | 0.04g | 0.07–0.12g | 0.15–0.20g |
| Wavy Cap | 1.5–2.5x | 0.03g | 0.05–0.08g | 0.10–0.15g |
| Azurescens | 1.8–2.5x | 0.02g | 0.04–0.07g | 0.08–0.12g |
Critical: Always grind your entire batch of dried mushrooms into a fine powder and mix thoroughly before measuring doses. Psilocybin content varies between individual mushrooms, between caps and stems, and between flushes. Homogenising ensures each dose is consistent.

Critical safety information for psilocybin microdosing
SSRIs & SNRIs
Fluoxetine, sertraline, escitalopram, venlafaxine, etc. Both increase serotonergic activity. Theoretical serotonin syndrome risk. SSRIs also blunt psilocybin’s effects significantly. Do NOT stop SSRIs abruptly to microdose — taper under medical supervision only.
Lithium
Multiple case reports associate lithium + psychedelics with seizures and psychotic episodes. This combination should be strictly avoided.
MAOIs
Extremely dangerous. MAOIs prevent serotonin breakdown while psilocybin adds serotonergic activity. Includes phenelzine, tranylcypromine, and natural MAOIs like Syrian rue.
Who should NOT microdose
Personal/family history of psychotic disorders (schizophrenia, bipolar I with psychotic features), anyone on lithium or MAOIs, pregnant or breastfeeding individuals, anyone under 18.
This is not medical advice. Always consult a healthcare professional before combining psilocybin with any medication.
7 common microdosing mistakes — and how to avoid them
Starting too high. Begin at 0.05g cubensis, not 0.15g. A perceptible dose is too high for microdosing.
Ignoring strain potency. 0.15g of Penis Envy is equivalent to ~0.27g of Golden Teacher. Always adjust.
Not homogenising. Psilocybin content varies between mushrooms. Grind and mix your entire batch into a powder.
Dosing daily. Tolerance builds within 1–3 days. No protocol recommends daily use. The Stamets Stack (4 on/3 off) is the maximum.
Dosing too late. Take your microdose in the morning (before 10 AM). Afternoon dosing can disrupt sleep via serotonergic stimulation.
Not keeping a journal. Without tracking, you can’t evaluate effects, adjust dose, or detect patterns. Track mood, energy, focus, and sleep daily.
Expecting instant results. Some benefits (especially mood and depression) build over days to weeks of consistent microdosing. Give any protocol at least 4 weeks.

Back to calculator ↑Frequently asked questions about microdosing mushrooms
How much shrooms for a microdose?
For standard P. cubensis (Golden Teacher, B+), a typical microdose is 0.05–0.25g dried, with 0.10–0.15g being the most common starting point. For Penis Envy strains, halve this (0.03–0.08g) as they are 1.5–2x more potent. The dose should be sub-perceptual — you should not feel “high.”
What are the benefits of microdosing mushrooms?
Commonly reported benefits include improved mood (26.6%), enhanced focus (14.8%), increased creativity (12.9%), reduced anxiety, and general well-being (Anderson et al. 2019). Clinical research also supports potential benefits for depression, cluster headaches, migraines, and addiction. However, the Szigeti et al. (2021) self-blinding study found improvements were not significantly greater than placebo.
Does microdosing psilocybin help with depression?
Full-dose psilocybin therapy shows strong results for depression (71% response rate in Davis et al. 2021). Microdosing evidence is more mixed: survey data consistently shows lower depression in microdosers (Rootman et al. 2021, N=8,703), but the controlled self-blinding study (Szigeti 2021) found improvements weren’t significantly greater than placebo. Many individuals report meaningful benefit, but more rigorous trials are needed.
What is the Fadiman protocol?
The Fadiman protocol, developed by James Fadiman PhD, is the most widely used microdosing schedule: dose on Day 1, rest on Day 2 (transition/afterglow), rest on Day 3 (normal baseline), then dose again on Day 4. Repeat for 4–8 weeks, then take 2–4 weeks off. This works out to roughly 2.3 doses per week.
What is the Stamets Stack?
Developed by mycologist Paul Stamets, the Stamets Stack combines psilocybin with Lion’s Mane mushroom (500–1000 mg) and niacin/vitamin B3 (50–100 mg, flushing form). The protocol is 4 days on, 3 days off. The theory is that Lion’s Mane promotes nerve growth factor (NGF) while niacin aids distribution. However, Rootman et al. (2021) found the stack was not significantly superior to psilocybin alone on most measures.
Can you microdose mushrooms every day?
No — psilocybin tolerance develops rapidly (within 1–3 days of consecutive use). Daily dosing leads to diminished effects and is not recommended by any established protocol. Even the Stamets Stack, the highest-frequency protocol, includes 3 rest days per week. Rest days are essential for tolerance reset and baseline comparison.
Can you microdose mushrooms for cluster headaches?
This is one of the most compelling applications. Sewell et al. (2006, Neurology) found that 25 of 48 psilocybin users reported complete cluster period termination. Many sufferers in the Clusterbusters community report relief at sub-hallucinogenic (microdose) levels. Schindler et al. (2021) showed a single low dose reduced migraine frequency by approximately 50%.
Can you microdose mushrooms while on antidepressants?
This requires extreme caution. SSRIs and SNRIs both increase serotonergic activity, creating a theoretical risk of serotonin syndrome when combined with psilocybin. SSRIs also significantly blunt psilocybin’s effects. Never stop antidepressants abruptly to microdose — SSRI withdrawal can be severe and must be managed under medical supervision. Consult your doctor before making any changes.
What are the side effects of microdosing mushrooms?
Commonly reported side effects include mild nausea (especially on an empty stomach), increased emotional sensitivity, slight headache, occasional fatigue on off-days, and difficulty sleeping if dosed too late. Anderson et al. (2019) also found 6.7% of microdosers reported increased anxiety. These effects are typically mild and dose-dependent.
How long should you microdose mushrooms?
Most protocols recommend 4–8 weeks of consistent microdosing followed by a 2–4 week break. The break is essential to reset tolerance, assess your baseline, and evaluate what changes are attributable to microdosing. Some people microdose cyclically for months; others use it as a periodic “reset.” Psilocybin does not produce physical dependence or withdrawal.
