Vaporized 5-MeO-DMT (GH001) produces dose-dependent increases in psychedelic experience intensity in healthy volunteers, with individualized dose escalation yielding maximal effects on peak experience, mystical experience, ego dissolution, and altered states of consciousness. Higher single doses (6, 12, 18 mg) significantly increased ratings compared to 2 mg on all measures except challenging experiences. Cognition, mood, and well-being were unaffected. Vital signs remained stable, and adverse events were mild and self-resolving. Individualized dose escalation may be preferable for clinical applications aiming to maximize the psychedelic experience for therapeutic response.
