Before you decide to cook with magic mushrooms, take note of dosage. Measuring magic mushrooms in grams is the most precise and convenient way to dose. One-tenth of a gram of magic mushrooms is enough for a mild microdose, while up to 2 grams per serving is good enough for beginners. If you are looking for a stronger, hallucinogenic experience, you may want to increase your dose to 3 or 4 grams for one serving.
