    Summary TheDrug.Wiki TripSit

    2-Chloroephenidine has the highest NMDA receptor affinity within the diphenidine family in vitro, though in vivo potency appears comparable to ephenidine. Very limited human safety data exists. Users report poorer urinary tract tolerance compared to other dissociatives and a steep dose-response curve above 150 mg.
