Self-experimentation refers to single-subject research in which the experimenter conducts the experiment on themself.
Usually this means that a single person is the designer, operator, subject, analyst, and user or reporter of the experiment.
Also referred to as Personal science or N-of-1 research,[1] self-experimentation is an example of citizen science,[2] since it can also be led by patients or people interested in their own health and well-being, as both research subjects and self-experimenters.
