<h1>The Stamets Stack: Psilocybin + Lion's Mane + Niacin</h1><div style="background:#f0fdf4;border-left:4px solid #16a34a;padding:16px 20px;margin-bottom:24px;border-radius:4px;"><strong>Direct Answer:</strong> The Stamets Stack combines psilocybin (0.1–0.3g), Lion's Mane mushroom (500–1000mg), and niacin (100–200mg) on a 5-days-on, 2-days-off schedule. The theory is that these three compounds synergistically enhance neuroplasticity.</div><h2>The Rationale</h2><p><strong>Psilocybin:</strong> Activates 5-HT2A receptors, promotes BDNF, disrupts DMN. <strong>Lion's Mane:</strong> Promotes Nerve Growth Factor (NGF), supporting neuron growth. <strong>Niacin:</strong> Vasodilator that may help deliver the other compounds across the blood-brain barrier.</p><h2>The Schedule</h2><p>5 days on, 2 days off (typically weekdays on, weekends off). More intensive than the Fadiman Protocol — better for people seeking maximum neuroplasticity effects.</p><div style="background:#1a0a2e;border:2px solid #7c3aed;border-radius:12px;padding:24px;margin:32px 0;text-align:center;"><p style="color:#e9d5ff;font-size:1.1em;margin-bottom:16px;font-weight:600;">Ready to experience the difference for yourself?</p><a href="https://secret.shrooomz.com/tabloid-checkout" style="background:#7c3aed;color:#fff;padding:14px 32px;border-radius:8px;text-decoration:none;font-weight:700;font-size:1.05em;display:inline-block;">Try Transformation Shrooomz →</a></div><h2>FAQ</h2><h3>Is the Stamets Stack better than the Fadiman Protocol?</h3><p>It's more intensive and theoretically more neuroplastic. But it's also more complex and may cause more side effects (niacin flush). The Fadiman Protocol is better for beginners.</p>
