Magic Mushroom Dosage Guide: How to Calculate Safe Psilocybin Doses
This magic mushroom dosage guide explains how to estimate psilocybin doses based on body weight, species (e.g., Psilocybe cubensis, Copelandia cyanescens), and whether material is fresh or dried. Use the dosage calculator above to get personalized ranges for microdose, standard, high, and "God Dose".
Baseline Ranges (Dried Psilocybe cubensis, 70 kg)
Microdose: 0.1 – 0.3 g
Standard: 1 – 2 g
High: 2.5 – 3.5 g
God Dose: 4 – 5 g
Weight Scaling
For example, at 84 kg (120% of baseline 70 kg), a 2 g standard dose becomes ~2.4 g.
Species & Material Adjustments
Copelandia cyanescens: ~70% stronger; we suggest ~30% of a cubensis amount.
Fresh mushrooms: ≈ ×10 vs dried due to ~90% water content.
Truffles (sclerotia): typically milder; we estimate −20% vs dried mushrooms.
Example Calculation
Choose Psilocybe cubensis, Dried, and enter 70 kg.
The calculator shows standard dose range of 1–2 g.
Switch to Fresh to see ~10–20 g due to water weight.
Select Copelandia cyanescens to see a ~70% reduction (≈30% of cubensis).
Safety & Set/Setting
Start low and increase only once you understand your sensitivity. Dose in a safe environment, ideally with a sober sitter for higher ranges. Avoid mixing with alcohol or other substances. Effects can take 30–120 minutes to peak.
A microdose is a sub‑perceptual amount, typically 0.1–0.3 g dried cubensis for a 70 kg person. It aims to enhance mood, focus, and creativity without producing a full psychedelic experience.
Fresh mushrooms contain about 90% water. As a rule of thumb, fresh weights are roughly ten times the dried equivalents. Our calculator applies this ×10 factor automatically.
Psilocybin truffles (sclerotia) are often milder by weight than dried fruiting bodies. We estimate truffle doses at −20% compared to dried mushrooms to reflect typical potency differences.
Copelandia (Panaeolus) cyanescens is considerably more potent than cubensis. As a conservative rule, use ~30% of an equivalent cubensis amount. Our calculator applies this automatically when selected.
Start low, go slow, and dose in a safe, comfortable setting. Wait at least 2–3 hours before taking more. Avoid mixing with alcohol or other substances. If in doubt, seek professional advice.
