Participate: Microdosing and the menstrual cycle

by | Nov 12, 2025

Maastricht University is seeking female participants who self-initiate in microdosing, for a study investigating the influence of microdosing on menstrual-related symptoms.

Microdosing with psychedelics is the practice of taking small (i.e., 10-20% of a dose that typically induces psychedelic effects) repeated doses of a psychedelic substance such as LSD or psilocybin over a period of time.

The study involves filling out a total of 9 weekly questionnaires throughout two menstrual cycles, covering menstrual-related symptoms such as body discomforts, changes in mood, memory or concentration.
