LA-Pip
Lysergic acid piperidide (LA-Pip or LSD-Pip), also known as N-piperidinyllysergamide, is a serotonin receptor modulator of the lysergamide family related to lysergic acid diethylamide (LSD). It is the analogue of LSD in which the N,N-diethyl substitution has been replaced with an N-piperidide ring.
