The right psilocybin dosage depends on your experience, the type of mushroom, your body, and the setting you are in. For most adults, doses generally fall into five ranges:
Minidose
— 50 to 100 mg
Microdose
— 100 to 300 mg
Chill Dose
— 0.5 to 1 g
Therapeutic Dose
— 1 to 3 g
Heroic Dose
— 3 to 5 g
All amounts on this page refer to dried mushroom material, not to milligrams of psilocybin. Figures assume Psilocybe cubensis, the species most commonly used.
Starting with a lower dose and giving yourself plenty of time to experience the effects is the safest approach, especially if you are new to psilocybin.
No dosage produces the same experience for everyone. The same amount can feel subtle for one person and overwhelming for another. Mushroom potency, your biology, recent food intake, medications, and mindset all influence how psilocybin affects you. Dosage charts are starting points, not guarantees.
The five psilocybin dose ranges
What is a minidose? (50 to 100 mg)
A minidose is designed to stay below the threshold of a typical psychedelic experience. Most people notice little to no change in mood or perception, although some report feeling slightly more focused, mentally clear, or creatively engaged. Because sensitivity varies from person to person, even this amount may feel more noticeable for some.
If you are new to psilocybin or want to understand how your body responds, a minidose is a cautious place to start. Even at this level, effects can differ depending on the mushroom’s potency, your individual sensitivity, and the environment you are in.
What is a microdose? (100 to 300 mg)
A microdose is intended to produce subtle effects without significantly changing your perception of reality. Many people report a gentle improvement in mood, greater focus, and increased attention while remaining able to carry on with their normal daily activities. Visual distortions and other classic psychedelic effects are generally not expected at this dose.
How do people schedule a microdose?
Most people who microdose follow a repeating schedule rather than dosing every day, because tolerance builds quickly. Two protocols are widely used and are named after the researchers who popularised them.
The Fadiman protocol is one day on, two days off, repeating on a three-day cycle. This is the more common starting point and is described in James Fadiman’s The Psychedelic Explorer’s Guide.
The Stamets Stack, developed by mycologist Paul Stamets, is four days on and three days off, with Lion’s Mane and niacin taken alongside psilocybin on dosing days.
Neither schedule is established as more effective than the other. Both exist to build in rest days rather than to maximise the amount taken.
What is a chill dose? (0.5 to 1 g)
A chill dose is where the psychedelic effects become clearly noticeable for many people while still feeling manageable. Commonly reported effects include mild euphoria, heightened sensory awareness, subtle visual changes such as brighter colours or gently shifting patterns, and increased introspection. Many people also find themselves feeling more emotionally open and present during the experience.
This range is often chosen by those who want to explore psilocybin beyond microdosing without committing to a more immersive experience.
What is a therapeutic dose? (1 to 3 g)
At 1 to 3 grams, the psychedelic effects become much more pronounced. Many people experience noticeable visual changes, deeper introspection, heightened emotional sensitivity, and a stronger sense of connection with themselves or the world around them. Because reactions vary widely, this range can feel profound for one person and emotionally challenging for another.
For context, clinical trials studying psilocybin for depression have generally used 25 mg of pure psilocybin, which is roughly equivalent to 2.5 grams of dried mushroom at typical potency.
This dose calls for thoughtful preparation. A safe, familiar environment, enough uninterrupted time, and a trusted sitter, especially for less experienced users, can make a significant difference if the experience becomes intense. Higher doses do not necessarily lead to better outcomes, which is why preparation matters as much as the amount you take.
What is a heroic dose? (3 to 5 g)
A heroic dose produces an intensely immersive psychedelic experience and should only be considered by highly experienced psilocybin users. At this range, intense visual and auditory changes, profound shifts in awareness, and a reduced sense of time, space, or self are commonly reported. Experiences at this dose can be emotionally powerful and unpredictable.
The term comes from Terence McKenna, who described five dried grams taken in silent darkness. It is worth knowing that this is a cultural convention rather than a research-derived figure. The highest dose studied in controlled research is roughly equivalent to 3 grams of dried mushroom, so the upper end of this range has not been formally studied.
Because of its intensity, this dose should only be taken in a safe, controlled environment with a trusted sober sitter present.
What changes the right psilocybin dosage?
One of the biggest misconceptions about psilocybin is that there is a perfect dose that works for everyone. In reality, the right psilocybin dosage varies from person to person. Two people can take the same amount from the same batch and have very different experiences.
That is because dosage is only one part of the equation. The potency of the mushrooms, your body, your mental state, and your surroundings all influence how the experience unfolds.
Why can the same mushroom dosage feel different every time?
Even if you always take the same amount, the effects may vary from one experience to the next. Several factors contribute to this:
- The concentration of psilocybin differs between mushroom species.
- Mushrooms from the same harvest can contain different amounts of active compounds.
- Storage conditions can gradually reduce potency over time.
- Your body and mind are never the same from one day to another.
Does body weight determine the right dose?
Largely, no. A pooled analysis of ten clinical studies using synthetic psilocybin found no evidence that body weight affected the subjective experience, across participants ranging from 49 to 113 kg. Psychological factors, expectations, previous experience, and individual biology appear to play a much larger role.
That does not mean body size is completely irrelevant, but it should not be the primary factor guiding your decision.
Why does mushroom potency vary so much?
Different mushroom species naturally produce different concentrations of psilocybin and psilocin, and even strains within the same species can differ. Growing conditions, including temperature, humidity, substrate, and harvesting practices, also influence potency. The part of the mushroom you consume and the way it is stored make a difference as well, since heat, oxygen, moisture, and light gradually degrade active compounds over time.
Analytical studies show substantial variation even among mushrooms grown under controlled, identical conditions. One study across fourteen strains found psilocybin content varying by roughly 13 to 23 percent between individual mushrooms of the same strain. Another found caps averaging around double the alkaloid content of stems, though variation between individual mushrooms was large enough that the difference was not statistically reliable.
Because of this, a dose that felt comfortable one month may feel significantly stronger from a different batch. It is also the reason third-party lab testing matters: a tested, standardised product removes a variable that dried mushroom material cannot.
Why do mindset and surroundings matter so much?
The most important factor shaping a psychedelic experience is often not the dose at all. Researchers have long emphasised two concepts known as set and setting.
- Set refers to your internal state, including your mood, expectations, emotional wellbeing, and intentions.
- Setting refers to your physical and social environment, including where you are and who you are with.
Consider two people taking the same amount. One spends the day in a quiet cabin with close friends after several weeks of preparation. The other takes the same amount at a crowded party while feeling stressed after a difficult week. The dose is identical. The experiences may be completely different.
Before taking psilocybin, ask yourself:
- Do I feel emotionally stable today?
- Am I in a place where I feel physically safe?
- Can I dedicate enough uninterrupted time?
- Is there someone I trust if I need support?
- Am I taking this intentionally rather than impulsively?
If the answer to several of these is no, postponing is often the wiser decision.
Why does previous experience matter more than confidence?
Confidence is not the same as experience. Someone who has never taken psilocybin has no personal reference point for how their mind and body will respond. Reading trip reports or talking with friends cannot replace that firsthand understanding.
If you are new to psilocybin, start at the lower end of the range, avoid increasing your dose, set aside an entire day, and let someone you trust know your plans.
Many difficult experiences happen not because someone chose an exceptionally high dose, but because they underestimated how strongly a moderate dose could affect them.
Should you take more if you do not feel anything?
Generally, no.
Onset usually occurs within 30 to 90 minutes, although food, metabolism, preparation method, and biological differences can make it take longer. A common mistake is assuming the mushrooms are not working and taking more too soon.
Wait at least two hours before deciding a dose was insufficient. Preparation methods such as tea or finely ground mushrooms may produce a faster onset than whole dried mushrooms. If the experience feels lighter than expected, adjust your dose another day rather than redosing.
How do you find the right dose over time?
Choosing the right psilocybin dose is not about finding the highest amount you can tolerate. It is about finding the amount that matches your intention.
Some people find a microdose fits comfortably into their routine. Others prefer occasional moderate experiences with careful preparation. There is no universally correct number.
Keeping a simple journal makes future decisions easier. Over time, your own notes become far more useful than comparing your experience to someone else’s. Worth noting each time:
- The amount you took
- The mushroom variety
- Whether you ate beforehand
- How long the effects took to begin
- How intense the experience felt
- Anything you would change next time
Risks and who should not take psilocybin
Psilocybin acts primarily on serotonin 5-HT2A receptors, producing changes in perception, emotion, and cognition. While many people describe meaningful or positive experiences, psilocybin also carries real risks. Understanding those risks matters as much as understanding dosage.
No amount of psilocybin can guarantee a positive experience, and no dose is completely risk-free.
Who should avoid taking psilocybin?
Current clinical research and safety guidelines generally recommend avoiding psilocybin if any of the following apply:
- You are pregnant or breastfeeding.
- You have a personal history of schizophrenia or another psychotic disorder.
- You have bipolar I disorder or a history of manic episodes.
- You have a close family history of schizophrenia or psychotic illness.
- You have uncontrolled cardiovascular disease, or another serious medical condition that could be affected by temporary increases in heart rate or blood pressure.
- You are taking medications that may interact with psilocybin.
Most clinical trials exclude participants with these risk factors because there is not enough evidence to establish safety in these groups.
Can psilocybin interact with antidepressants or other medications?
Yes. Understanding these interactions is an important part of reducing risk.
SSRIs
SSRIs, including sertraline (Zoloft), fluoxetine (Prozac), and escitalopram (Lexapro), may reduce the subjective effects of psilocybin for some people.
The research is genuinely unsettled here. One controlled study found that two weeks of escitalopram did not reduce the positive effects of psilocybin, and did reduce adverse effects such as anxiety. A large survey of real-world users found the opposite, with effects reported as diminished both during antidepressant use and for a period after stopping. Both findings are credible and neither settles the question.
Do not stop taking prescribed antidepressants in order to increase the effects of psilocybin. Abruptly discontinuing SSRIs can cause withdrawal symptoms and may worsen underlying mental health conditions.
MAOIs
Monoamine oxidase inhibitors may alter the metabolism of psilocybin and potentially increase or prolong its effects. Because MAOIs carry numerous medication and dietary interactions of their own, combining them with psychedelics may increase the risk of adverse effects.
Other psychiatric medications
Research on interactions between psilocybin and mood stabilisers, antipsychotics, benzodiazepines, stimulants, and other psychiatric medications remains limited. Some may reduce psychedelic effects, others may increase certain risks. If you take prescription medication, do not rely on anecdotal reports online.
What if you start feeling anxious during the experience?
Even well-prepared experiences can become emotionally intense. This does not necessarily mean something is going wrong. Psilocybin often amplifies emotions that are already present, including fear, sadness, excitement, or uncertainty.
If this happens, a few simple principles help:
- Remind yourself that the effects are temporary
- Focus on slow, steady breathing
- Move to a quieter or more comfortable environment if possible
- Stay hydrated
- Avoid making important decisions during the experience
- Accept difficult emotions rather than fighting them
A calm, reassuring person nearby can make a significant difference if the experience becomes overwhelming.
What are the most common side effects?
Most side effects are temporary and resolve as the experience wears off. Commonly reported:
- Nausea or stomach discomfort
- Temporary increases in heart rate
- Temporary increases in blood pressure
- Dilated pupils
- Dizziness
- Sweating or chills
- Changes in body temperature perception
- Emotional sensitivity
- Difficulty concentrating
- Temporary anxiety or fear
Clinical studies generally report that these resolve without lasting physical complications in healthy participants who were screened appropriately.

Psilocybin is a Schedule I controlled substance under US federal law. Some states and cities have changed how psilocybin is treated locally. Understanding the law where you live is your responsibility.
The dose ranges on this page are drawn from published research and from what people commonly report. They are starting points, not prescriptions. Potency varies between species, between strains, and between individual mushrooms from the same harvest, so the same weight will not always produce the same experience.
If you take prescription medication, particularly antidepressants, or if you have a heart condition or a personal or family history of psychosis or bipolar disorder, speak with a healthcare provider before considering psilocybin.
