This tool helps estimate a safe and effective dose of psilocybin-containing mushrooms or truffles based on your weight, sex, form (dried or fresh), and desired trip intensity (micro, moderate, strong, or heroic). It includes visual feedback via a chart and guidance notes for harm reduction.
Both contain psilocybin, but truffles (sclerotia) are the underground parts of certain mushroom species. Truffles generally have a lower psilocybin concentration than dried mushrooms — the calculator adjusts doses accordingly.
You can select either! Dried mushrooms are around 10x more potent by weight than fresh ones because most of the water has been removed. The calculator factors this in automatically when you choose your form.
While psilocybin isn’t dosed strictly per kilogram like some medications, body size and biological sex can influence metabolism and intensity. These inputs help slightly fine-tune your recommended range.
The calculator provides general guidance based on known dosage ranges from experience reports and research. Individual responses vary based on tolerance, mindset, and setting. It’s not a medical tool — always proceed with caution and awareness.
Psilocybin is a controlled substance in many countries. This calculator is provided for educational purposes only. Always follow your local laws and regulations.
