How to Dose Magic Mushrooms

Everything comes down to a scale, a starting point, and the patience to work up slowly.

Dosage Guides  |  ShroomTown  |  August 8, 2026

Dosing magic mushrooms is less about finding a fixed right amount and more about finding your amount. Two people eating the exact same 1.5 grams from the exact same batch can walk away with two different experiences, depending on body weight, tolerance, mindset, and even how empty their stomach is. That variability is normal, but it’s also exactly why a scale and a plan matter more than a rule of thumb passed around online.

This guide walks through the main factors that affect dosage, a gram-by-gram breakdown by intensity, what a typical timeline looks like, and how to responsibly find your own baseline if you’re just starting out.

What Actually Affects Your Dose

Before looking at any chart, it helps to understand why the right dose isn’t the same for everyone. A few variables do most of the work:

  • Species and potency: Not all dried mushrooms are created equal. A gram of a high-potency species can hit noticeably harder than a gram of a milder one, so a dose that works for one variety may be too strong or too light for another.
  • Body weight and metabolism: Larger body mass generally means a given dose is felt less intensely, though this isn’t a hard rule.
  • Tolerance and experience: Frequent use builds tolerance quickly, and prior psychedelic experience changes how comfortable someone is at a given intensity.
  • Food intake: Eating on an empty or lightly filled stomach speeds onset and can intensify effects. A heavy meal beforehand tends to dull and delay them.
  • Set and setting: Mindset going in and the physical environment shape the experience as much as the dose itself, especially at higher amounts.

Pro Tip

Always weigh dried mushrooms on a digital milligram scale rather than eyeballing a portion by cap count or size. Density varies piece to piece, so one medium cap can swing by half a gram or more between mushrooms.

Dosage Chart by Intensity

The ranges below are general starting points for dried mushrooms, not fixed prescriptions. If you’re new to psilocybin, start at the low end of a range and give it several days before adjusting.

Microdose  |  0.1g to 0.3g

Sub-perceptual. No noticeable trip. Used by many for focus, mood, and creativity as part of a daily or every-few-days routine rather than a standalone experience.

Threshold Dose  |  0.3g to 0.7g

The first noticeable shift: mild mood lift, subtle sensory change, a light mental edge without full psychedelic effects. Often used to test personal sensitivity before going further.

Light to Moderate Dose  |  1g to 2g

A gentle, manageable experience with noticeable mood and perceptual changes while still retaining clarity and conversational ability. A common range for social or reflective settings.

Common Full Dose  |  2g to 3.5g

A complete, classically psychedelic experience: visual effects, introspection, and altered perception of time. Best reserved for a dedicated block of time in a familiar, comfortable setting with nothing else planned.

Strong to Heavy Dose  |  4g and up

An intense, often ego-dissolving experience sometimes called a heroic dose. Only appropriate for experienced users, ideally with a sober trip sitter present, and never as a starting point.

What a Typical Session Looks Like

Once ingested, dried mushrooms generally follow a predictable arc, though timing varies by dose and individual:

  • Onset: 20 to 45 minutes after ingestion, faster on an empty stomach
  • Come-up: A building phase over the next 30 to 60 minutes
  • Peak: Roughly 1.5 to 3 hours after onset, depending on dose
  • Comedown: A gradual taper over 1 to 2 hours
  • Total duration: Approximately 4 to 6 hours from onset to baseline

A note on individual variation: Body weight, metabolism, food intake, and even mindset going into a session can all shift how a given dose feels. Two people taking the identical amount of the same batch can have noticeably different experiences. Starting conservatively and adjusting gradually over multiple sessions is the most reliable way to find your own baseline.

Choosing a Format

Whole dried mushrooms give you the most direct control over dosage, since you are weighing the material yourself for each session. For people who want a consistent, low-effort way to work with smaller amounts, our microdose capsules offer a fixed dose per capsule without needing a scale each time. For a structured, higher-dose session, our precision dosed chocolate bar breaks a full dose into even, labeled squares. Browse the full range of magic mushroom products or shop all to compare formats.

A note on safety: Psilocybin mushrooms can interact with certain medications (notably SSRIs, SSNRIs, and lithium) and are not recommended for anyone with a personal or family history of psychosis. If you’re on medication or have a relevant health history, talk to a doctor before use. Start low, go slow, and never dose alone for your first few experiences.

Final Thoughts

There’s no universal correct dose, only one that’s right for you, on that day, with that batch. The most reliable path is the least exciting one: weigh your material, start conservatively, keep notes on how each amount felt, and adjust gradually over multiple sessions rather than guessing your way to a strong dose on day one. Once you know your baseline, everything from microdosing to a full immersive session becomes a lot more predictable, and a lot safer.
