Psilocybin 101 Psilocybin is the psychoactive compound in "magic mushrooms." When ingested, it converts to psilocin, altering serotonin receptors in the brain. Effects begin within 30–60 minutes, ranging from euphoria to visual distortions. Dosage matters—start low (1–2g dried) to gauge sensitivity. Always test substances for purity, as misidentified mushrooms can be deadly. https://alprahealth.com/en_us/product-category/magic-mushrooms/
