Lysergic acid dipropylamide

Lysergic acid dipropylamide (LSDP), also known as N,N-dipropyllysergamide (DPL), is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). It is the analogue of LSD in which the amide group has two propyl substitutions instead of two ethyl substituents.
