Also known as 1B-LSD, 1bPW

1B-LSD (1-butanoyl-lysergic acid diethylamide) is an LSD analogue which appears to be about as potent as 1P-LSD (slightly more potent than LSD) and has a slightly shorter duration than that of LSD, again thought to be about the same as 1P-LSD. Released in late 2018, and marketed agressively as a replacement for 1P-LSD. 1B-LSD does not yet have a clearly established safety profile,TS
