Lysergic Acid Methyl Ester
is an analogue of Lysergic Acid Diethylamide
, or LSD-25, though it may be 2-3 times more potent. Like LSD, it is active at extremely low doses (measured by micrograms). It is a member of the tryptamine
family and is extremely uncommon. It acts on the 5-HT receptors in the brain, as do most tryptamines.
