Homo-MDA

Homo-MDA, also known as α-methyl-γ-propylamine, is a entactogen-like drug related to 3,4-methylenedioxyamphetamine. It is an analogue of MDA in which the side chain has been lengthened by one carbon atom.
Unlike the stimulant amphetamine and the psychedelic DOM, and in contrast to MDA, homo-MDA has no effect on locomotor activity in rodents. It was found to be more toxic than MDA in rodents.
The effects of homo-MDA in humans are unknown. It is not a controlled substance in the United States as of 2011.
