What is the Stamets Stack?
The Stamets Stack, developed by renowned mycologist Paul Stamets, is an enhanced microdosing protocol that combines psilocybin mushrooms with Lion's Mane mushroom and niacin (vitamin B3). Stamets theorizes this combination creates a synergistic effect that enhances neuroplasticity beyond psilocybin alone.
💡 The Theory
Stamets proposes that Lion's Mane stimulates nerve growth factor (NGF), psilocybin enhances neuroplasticity, and niacin acts as a "delivery mechanism" by dilating blood vessels and causing a peripheral flush that may help distribute compounds throughout the brain and peripheral nervous system.
The Three Components
🍄 Psilocybin Mushrooms
Dose: 0.1-0.3g dried
Role: Primary psychoactive, promotes neuroplasticity
- 5-HT2A receptor agonist
- Promotes neural connectivity
- Enhances creativity and mood
- Reduces default mode network activity
🦁 Lion's Mane (Hericium erinaceus)
Dose: 500-1000mg extract
Role: Nerve growth factor (NGF) stimulation
- Promotes neuron growth and repair
- Enhances cognitive function
- Neuroprotective properties
- May improve memory and focus
🔥 Niacin (Vitamin B3)
Dose: 100-200mg (flush dose)
Role: Peripheral vasodilation, "delivery mechanism"
- Causes temporary flush/tingling
- Increases blood flow
- May enhance compound distribution
- Cardiovascular benefits

Detailed Dosage Guidelines
Component Dosages
| Component | Starting Dose | Standard Dose | Max Dose |
|---|---|---|---|
| Psilocybin Mushrooms | 0.1g | 0.1-0.3g | 0.5g |
| Lion's Mane Extract | 500mg | 500-1000mg | 3000mg |
| Niacin (flush) | 50mg | 100-200mg | 200mg |
Important Notes
- Lion's Mane: Use extract (not whole mushroom powder) for standardized dosing
- Niacin Type: Use immediate-release niacin (NOT "no-flush" or time-release)
- Timing: Take all three components together in the morning with food
- Scales: Use accurate scale (0.01g precision) for psilocybin
The Niacin Flush: What to Expect
⚠️ Niacin Flush is Normal!
If you've never taken niacin before, the flush can be surprising. It's safe and temporary (20-40 minutes).
Niacin Flush Sensations
- Skin Redness: Face, neck, chest turn red (looks like sunburn)
- Tingling/Prickling: Mild to intense pins-and-needles sensation
- Warmth: Feeling of heat spreading through body
- Itching: Some people experience mild itching
- Duration: Peaks at 20-30 minutes, fades by 40-60 minutes
Managing the Flush
- Start with 50mg niacin to assess your sensitivity
- Take with food to reduce intensity
- Stay hydrated before dosing
- The flush becomes less intense with regular use
- Don't take antihistamines before (they block the flush - defeating the purpose)
- Avoid hot showers immediately after dosing
🚨 Avoid "No-Flush" Niacin
Do NOT use niacinamide or "no-flush" niacin. The flush is the point - it's what causes vasodilation. Without the flush, you're just taking vitamin B3 without the hypothesized synergistic effect.

How to Prepare Your Stack
Method 1: Capsules (Recommended)
Most convenient and accurate method
- Grind dried psilocybin mushrooms to fine powder
- Weigh 0.1-0.3g psilocybin powder per capsule
- Add 500mg Lion's Mane extract powder to same capsule
- Close capsule (size 00 works well)
- Take with 100-200mg niacin tablet
- Store in airtight container away from light
Method 2: Separate Dosing
- Weigh psilocybin dose daily (0.1-0.3g)
- Take Lion's Mane capsule (500-1000mg)
- Take niacin tablet (100-200mg)
- Consume all together with water and light food
What You Need
- Equipment: Digital scale (0.01g precision), coffee grinder, empty capsules (optional)
- Psilocybin: Dried cubensis mushrooms (Golden Teacher, B+ recommended for beginners)
- Lion's Mane: Extract powder or capsules (look for 30%+ polysaccharides)
- Niacin: Immediate-release tablets (NOT no-flush type)
Tracking Your Progress

Common Questions & Troubleshooting
The niacin flush is too intense - what do I do?
Reduce niacin dose to 50mg and work up gradually. Take with food. The flush becomes less intense with regular use. If it remains unbearable, you can reduce or eliminate niacin - the psilocybin + Lion's Mane combination still offers benefits.
Can I continue Lion's Mane on rest days?
Yes! Many practitioners take Lion's Mane daily (including rest days) for consistent nerve growth factor stimulation. This won't interfere with the psilocybin tolerance reset.
Is the Stamets Stack safe?
While individual components are well-studied, the specific combination has not undergone clinical trials. All three components have long safety profiles individually. Consult healthcare provider, especially if taking medications.
Do I need all three components?
Psilocybin + Lion's Mane is the core combination for neuroplasticity. Niacin is theorized to enhance distribution but is optional. Start with just psilocybin + Lion's Mane if niacin is uncomfortable.
How long until I notice results?
Some effects (mood, focus) may appear within days. Neuroprotective benefits are long-term. Most people notice significant cognitive improvements after 2-3 weeks of consistent stacking.
Can I use the Stamets Stack for microdosing long-term?
Follow a cycling schedule: 4 weeks on, 2-4 weeks off. This prevents tolerance and allows you to assess baseline state. Lion's Mane can be continued during breaks if desired.

The Science Behind the Stack
Psilocybin & Neuroplasticity
Research shows psilocybin promotes dendritic spine growth, increases synaptic connections, and enhances neural plasticity through 5-HT2A receptor activation.
Lion's Mane & NGF
Studies demonstrate Lion's Mane contains hericenones and erinacines that stimulate nerve growth factor synthesis, supporting neuron growth and myelination.
Niacin & Vasodilation
Niacin causes peripheral vasodilation via prostaglandin release. Stamets hypothesizes this may enhance compound distribution throughout nervous system.
⚠️ Safety Considerations
- Consult healthcare provider before starting
- Niacin can interact with blood pressure medications
- High-dose niacin may affect liver function (100-200mg is safe)
- Not recommended during pregnancy/breastfeeding
- Avoid if you have schizophrenia or bipolar disorder
- Check for medication interactions (especially SSRIs)
