Best practice indicates that a body weight derived dosage of psilocybin of 0.3mg / kg or 25mg should be used<ref>'''Pharmacokinetics of escalating doses of oral psilocybin in healthy adults'''. Brown RT, Nicholas CR, Cozzi NV, Gassman MC, Cooper KM, Muller D, et al. Clin Pharmacokinet. (2017) 56:1543–54. </ref>. This normal dose has also been found to have substantially better clinical outcomes than lower doses such 10mg or microdosing<ref>'''Single-Dose Psilocybin for a Treatment-Resistant Episode of Major Depression'''.

This equates to 10–20µg l–1 psilocin in plasma, which corresponds to ~60% occupancy of serotonin 2A (5-HT2A) receptors in the neocortex of humans.<ref>'''Psychedelic effects of psilocybin correlate with serotonin 2A receptor occupancy and plasma psilocin levels'''. MK Madsen Neuropsychopharmacology, first published 2019. Accessed on 5th November 2022 via https://www.nature.com/articles/s41386-019-0324-9</ref> Psychological effects start around 10–40 min after ingestion and last for 2–6 h. | |||
