LSD-Pip
# LSD-Pip

LSD-Pip is a compound from the ergoline family, related to LSD but with the N,N-diethyl substitution replaced by a piperidine group. It is more potent than the corresponding pyrrolidine and morpholine analogues (LPD-824 and LSM-775 respectively), but is still several times less potent than LSD as a $5-HT_{2A}$ agonist. Early studies suggested this compound to be inactive as a psychedelic in humans, though this does not seem to have been confirmed by any more recent work.
