1cP-LSD is a semisynthetic psychedelic of the lysergamide class and an acylated derivative of LSD. It was first developed by Lizard Labs around 2019 as a legal alternative following the anticipated prohibition of 1P-LSD in Germany. It is structurally related to other LSD analogs such as 1P-LSD, 1B-LSD, and ALD-52. Research has demonstrated that it functions as a prodrug of LSD, with anecdotal reports describing near-identical effects.
