Magic Mushroom Dosage Calculator
Introduction & Importance of Proper Mushroom Dosage
Magic mushrooms (psilocybin-containing fungi) have been used for centuries in spiritual and therapeutic contexts. Modern research from institutions like Johns Hopkins University demonstrates their potential for treating depression, anxiety, and PTSD when used responsibly. However, proper dosing is critical to ensure both safety and effectiveness.
This comprehensive dosage calculator helps you determine the appropriate amount based on:
- Your body weight (psilocybin effects are weight-dependent)

Formula & Methodology
Our calculator uses a scientifically-backed algorithm that considers:
1. Base Dosage Calculation
The foundation uses the standard psilocybin dosage ranges established by clinical research:
| Experience Level | Microdose (mg) | Low Dose (mg) | Moderate Dose (mg) | High Dose (mg) | Heroic Dose (mg) |
|---|---|---|---|---|---|
| Beginner | 1-3 | 5-10 | 10-20 | 20-30 | 30+ |
| Intermediate | 2-5 | 10-15 | 15-25 | 25-35 | 35+ |
| Advanced | 3-7 | 15-20 | 20-30 | 30-40 | 40+ |
2. Weight Adjustment Factor
We apply a weight adjustment using the formula:
Adjusted Dosage = Base Dosage × (User Weight / 70)⁰·⁷
This accounts for metabolic differences while preventing linear scaling that could be dangerous for heavier individuals.
3. Strain Potency Multiplier
Different strains contain varying psilocybin concentrations:
- Psilocybe cubensis: 1.0× (standard)
- Psilocybe azurescens: 1.2× (20% more potent)
- Psilocybe mexicana: 0.8× (20% less potent)
4. Conversion Factors
We provide conversions for different consumption methods:
- Dried mushrooms: 1g ≈ 10mg psilocybin (standard assumption)
- Fresh mushrooms: 1g ≈ 1mg psilocybin (10:1 water weight ratio)
- Tea strength: 1.5× absorption rate compared to eating
Real-World Examples

Interactive FAQ
How accurate is this dosage calculator compared to professional guidance?
Our calculator uses the same fundamental principles as clinical studies, but individual responses to psilocybin can vary based on:
- Unique brain chemistry and serotonin receptor density
- Current mental state and expectations
- Metabolism and liver enzyme activity
- Stomach contents and digestion speed
- Simultaneous use of other substances
For therapeutic use, we recommend consulting with a professional through organizations like MAPS (Multidisciplinary Association for Psychedelic Studies).
Can I develop tolerance to magic mushrooms?
Yes, psilocybin tolerance develops rapidly due to serotonin receptor downregulation. Key points:
- Taking mushrooms two days in a row requires 2-3× the dose for similar effects
- Tolerance returns to baseline after 7-14 days
- Microdosing protocols typically use a 1 day on, 2 days off schedule
- Frequent use (more than once every 2 weeks) may lead to diminished benefits
Research from this 2017 study shows that tolerance affects both the psychoactive and potential therapeutic effects.
What’s the difference between dried and fresh mushrooms?
Fresh mushrooms contain about 90% water by weight. The conversion is:
- 1g dried ≈ 10g fresh (standard ratio)
- Fresh mushrooms degrade quickly (use within 3-5 days)
- Dried mushrooms last years when stored properly (airtight, dark, cool)
- Potency is identical when adjusted for water content
Example: If your dose calculates to 2g dried, you would need approximately 20g fresh for equivalent effects.
Are there any medical conditions that make mushroom use dangerous?
Psilocybin is not recommended for individuals with:
- Personal or family history of psychosis or schizophrenia
- Current diagnosis of bipolar disorder (risk of mania)
- Severe heart conditions (can temporarily increase heart rate)
- Active severe depression without professional support
- Current use of lithium (potential dangerous interaction)
Always consult a healthcare provider before use if you have any mental health concerns. The National Institute of Mental Health provides excellent resources for understanding risks.
How does lemon tek affect dosage calculations?
The lemon tek method (soaking mushrooms in lemon juice) affects the experience in several ways:
- Faster onset: Effects begin in 15-30 minutes vs. 45-60 minutes
- Shorter duration: Total experience may be 20-30% shorter
- Potentially stronger effects: Some users report 1.2-1.5× intensity
- Reduced nausea: Citric acid helps break down chitin in mushroom cell walls
Dosage adjustment: We recommend reducing your calculated dose by 20% when using lemon tek to account for increased potency.
What’s the legal status of magic mushrooms where I live?
Laws vary significantly by location. Current status in major regions:
- United States: Federally illegal (Schedule I). Decriminalized in Oakland, Denver, Washington DC, and Oregon (regulated therapeutic use)
- Canada: Illegal but some exemptions for end-of-life care. Decriminalization efforts ongoing
- Netherlands: “Truffles” (sclerotia) are legal, mushrooms are not
- Portugal: Decriminalized for personal use (all drugs)
- Brazil: Legal for religious use in approved ceremonies
- Australia: Illegal, though some clinical trials approved
Always check your local laws as they change frequently. The DEA (US) and UNODC provide official information.
How can I test my mushrooms for potency or contaminants?
Testing is crucial for safety. Here are your options:
- Home test kits:
- Ehrlich reagent tests for psilocybin presence (~$20)
- Marquis reagent can rule out dangerous contaminants
- Available from DanceSafe or Bunk Police
- Laboratory testing:
- More accurate but expensive ($100-$300)
- Tests for potency, heavy metals, pesticides, and mold
- Companies like Analytical 360 offer mail-in services
- Visual inspection:
- Look for blue bruising (indicates psilocybin)
- Avoid mushrooms with dark spots (potential mold)
- Check for unusual odors (ammonia-like smells are bad)
Never consume mushrooms that haven’t been properly identified by an expert or tested if you’re unsure of the source.
