In risk mitigation in psychedelic treatment, dose figures are most useful when read as one component of a full research protocol: participant selection, medication review, preparation, setting, observation, response planning, and follow-up all shape the safety context. A useful starting point is the broader risk-management overview, which frames dosing as a decision that should never be separated from eligibility and acute safeguards.
Contemporary psilocybin trials have commonly used fixed, session-level doses such as 20 mg or 25 mg, while some earlier studies used weight-based dosing. MDMA-assisted therapy studies have commonly used an initial dose with a supplemental dose later in the session; ketamine research spans intravenous, intramuscular, intranasal, and oral approaches with materially different pharmacokinetics and observation needs. These published figures describe study procedures rather than universal recommendations. The ClinicalTrials.gov study record system can help readers locate the protocol context behind a trial rather than treating a headline dose as a standalone instruction.
Other substances discussed in psychedelic research have less consistent contemporary safety evidence, particularly across non-research settings. Dose comparisons can therefore be misleading when formulation, route, concomitant medicines, prior exposure, medical history, or support conditions differ. The ibogaine and brain-aging resource is relevant here because pharmacologic risk cannot be inferred from a substance label alone.
