Experimental: Psilocybin, Dose A
Single oral dose during an 8-hour supervised session (Specific dose withheld during conduct).
|
The specific doses (in mg) are intentionally omitted from this registration during the conduct of the trial to preserve masking and reduce expectancy effects.
The doses will be disclosed when results are reported after primary completion, by which point participants have been debriefed.
