Iso-LSD, also known as d-iso-LSD, (+)-iso-LSD, or (5R-8S)-LSD, as well as N,N-diethylisolysergamide, is a serotonin receptor modulator of the lysergamide family related to lysergic acid diethylamide (LSD). It is the 8-position epimer of LSD, with iso-LSD being 8α (8S) and LSD being 8β (8R). Iso-LSD is also the N,N-diethyl derivative of isoergine (isolysergic acid amide; iso-LSA), a constituent found in morning glory seeds. Iso-LSD is one of four possible stereoisomers of LSD.
