Determining the right dosage is crucial for a safe and intentional experience. Our shroom calculator helps you estimate the ideal amount of psilocybin mushrooms based on your body weight, mushroom type, and desired intensity level.
Shroom Calculator
Shroom Calculator Formula:
Reference Source: Johns Hopkins Psychedelic Research
Variables:
- Body Weight: Used to normalize the metabolic rate (Base: 70kg).
- Species Potency: Different species (e.g., P. Cubensis vs. Azurescens) have varying psilocybin concentrations.
- Mushroom State: Fresh mushrooms contain ~90% water, requiring a 10x multiplier compared to dried.
- Intensity: Categorized from Micro (0.2g base) to Heroic (5.0g base).

What is a Shroom Calculator?
A shroom calculator is a digital tool designed to help users estimate the appropriate amount of psilocybin mushrooms for a specific experience. Because the potency of mushrooms can vary wildly and individual sensitivity is affected by body mass, using a calculator reduces the risk of “accidental heroic doses.”
It acts as a harm-reduction tool by integrating data from clinical studies and community reports to provide a baseline for beginners and experienced users alike.
How to Calculate Shroom Dosage (Example):
- Identify your body weight (e.g., 80kg).
- Select your intensity (e.g., Moderate = 2.5g base).
- Adjust for weight: 2.5g × (80 / 70) = 2.85g.
- Adjust for species: If using Azurescens (0.5x), dose becomes 1.42g.
Frequently Asked Questions (FAQ):
Is the dosage the same for everyone? No, metabolism, stomach content, and individual brain chemistry play significant roles.
Why does the species matter? Some species like Psilocybe Azurescens are up to 3 times stronger than common Cubensis.
Can I use this for truffles? Yes, ensure you select “Truffles” as they are much less potent by weight than dried mushrooms.
How long should I wait between doses? Psilocybin tolerance builds rapidly; it is usually recommended to wait 1-2 weeks for a full reset.
