" MDAT is also known as 6,7-Methylenedioxy-2-aminotetralin. This research chemical was developed in 1900s. The father of MDAT is David E.br Nichols who discovered 6,7-Methylenedioxy-2-aminotetralin in the process of chemical research. Its action is described as that of serotonin releasing agent. Chemical companies that supply MDAT say that it is non-neurotoxic entactogen. MDAT formula is C11H13NO2 n its molecular mass 191.223 gmol. Due to the lack of neurotoxicity its supply n sale is not controlled by law. Chemical companies supply MDAT in the form of crystallized powder. Though MDAT is supplied for research purposes only it is reported that 6,7-Methylenedioxy-2-aminotetralin is taken orally by some people. They claim that MDAT is a full substitute of ""Exstasy"" lacking its serotonergic neurotoxicity. The user who buy MDAT say it is stronger than MDAI n confirm that effects of this research chemical are close to those of MDMA, though weaker n lighter.
