Safety of GH001 in Healthy Volunteers


Brief Summary

The aim of the study is to investigate the safety of GH001 (containing 5-methoxy-dimethyltryptamine; 5-MeO-DMT), and its dose-related psychoactive effects in healthy volunteers. The study will evaluate single, ascending doses of GH001 in Part A and an individualized dosing regimen of GH001 in Part B.
