    Summary Erowid

    MDPR is a synthetic phenethylamine. Very little is known about its possible effects as there is nearly no history of human use.

    Perspectives

    “There are the slightest hints of physical response, maybe a smidgin of a lightheadedness at the one hour point. Perhaps a slight teeth clench. Certainly there is no central mental effect.”
