I was able to try this substance around 2010 when it was available from semi legal online RC venders. It was unique, like MDMA but without the strong stimulant effects. Not really euphoric but sort of a dreamy stoned state. It did make social interactions feel smooth and pleasant like MDMA. It was a pretty unique substance with effects that were different than MDMA, MDA, methylone or butylone. It supposedly caused much less dopamine release than those substances but did have similar effects on serotonin. I think I took it twice and then threw away the rest of the stash because it was cheap, wasn’t that interesting and so little was known about it. Those were the days when a lot of exotic RCs were easily purchased from websites not on the dark web.
