1P-LSD Blotters 100 mcg support research into lysergamides. The molecule, known as 1-propionyl-D-lysergic acid diethylamide, includes a propionyl group on the indole nitrogen and a polycyclic system formed by a bicyclic hexahydroindole fused to a bicyclic quinoline group. Its structure closely relates to ALD-52, with a small difference in the attached acyl group.
