What is a typical dose for psilocybin?

For microdosing, typically, the goal of microdosing is not to produce noticeable or profound changes in cognition and perception. Data from recent systematic reviews on low-dose psychedelics by Vince Polito and Paul Liknaitzky, and Joseph Rootman and colleagues summarizes microdose quantities used in past research. As an estimate, a microdose is between approximately one tenth and one twentieth of a typical recreational dose. Since an effective recreational dose can vary substantially from one individual to the next, use a conservative “low and slow” approach and start as low as possible as you identify an appropriate dose, especially if you aren’t sure of how much you’re giving yourself. Track your progress carefully and accurately through written records. Polito and Liknaitzky, and Rootman and colleagues, provide the following plausible dose ranges for microdoses of Psilocybe cubensis dried mushroom, oral ingestion: 0.1-0.5g/70kg (per 70kg bodyweight); Low dose ≤ 0.1g; Medium dose = 0.1-0.3g; High dose ≥ 0.3g.
