Example Calculation
Scenario: User wants a moderate trip with Golden Teacher mushrooms (dried).
- 1. Experience Level: Moderate Trip (12-18 mg)
- 2. Strain Family: P. Cubensis
- 3. Specific Strain: Golden Teacher (0.63%)
- 4. Mushroom Form: Dried
Result: 1.9g - 2.9g of dried Golden Teacher mushrooms needed.
Why? Golden Teacher contains approximately 0.63% psilocybin. To consume 12-18mg of the active compound, you need roughly 2 to 3 grams of dried mushroom material.
The Math behind the Magic:
To find the weight in grams, we divide the target dose (mg) by the concentration of psilocybin in the mushroom.
Formula:
Weight (g) = Target Dose (mg) / (Percentage × 10)
Step 1 (Convert % to mg/g):
0.63% means there are 6.3mg of psilocybin in every 1 gram of dried mushroom.
Step 2 (Calculate Range):
Min: 12mg / 6.3 = 1.90g
Max: 18mg / 6.3 = 2.85g
Result: You need between 1.9g and 2.9g.
⚠️ Important Canadian Harm Reduction Disclaimer
As we work toward establishing our physical retail store and laboratory in Vancouver, British Columbia, our commitment to community safety remains a top priority. Please note that the results provided by this Canadian magic mushroom dosage calculator are based on average potency values. In nature, the psilocybin content of magic mushrooms can vary significantly due to genetics, species, and local growing conditions. Active compound levels can differ even within the same flush or within the exact same mushroom.
Always start with a low dose to assess your individual sensitivity. For educational purposes, safe application, and comprehensive psilocybin harm reduction guidelines in Canada, read more here .
FAQ
Frequently Asked Questions
Quick answers to the most common questions about finding your ideal dose, staying safe, and understanding the effects.
Our calculator gives a reliable estimate based on the average active compound levels for each strain. Keep in mind that these are averages, as actual potency can vary between individual mushrooms and even between different flushes of the same strain, so it's always best to start low.
No fatal overdose from psilocybin mushrooms has ever been recorded. However, taking too much is still possible and can lead to an overwhelming and frightening experience known as a bad trip. This state can be psychologically very challenging, deeply distressing, and difficult to manage alone.
For beginners, we strongly recommend starting low, around 1g to 1.5g of dried Cubensis. This approach lets you safely explore how your body and mind react to psilocybin for the very first time. You can always take a larger dose on a future occasion once you know exactly how you respond.
You'll typically feel the first effects within 30 to 60 minutes. This can vary depending on whether you've eaten beforehand, since a full stomach tends to slow down absorption quite considerably. The overall experience usually lasts somewhere between 4 to 6 hours from start to finish.
Fresh mushrooms consist of roughly 90% water, so the drying process concentrates the active compounds significantly by weight. This means you generally need about 10 times less dried mushrooms compared to fresh ones to achieve the exact same effect, which is a big difference worth knowing.
Body weight, age, and gender have no significant or reliable impact on the intensity of a psilocybin experience, according to scientific studies. What matters most is the specific dose you take and your own individual sensitivity as well as any prior personal experience with psilocybin.
