Yeah, I was trying to explain. And also, that it would be better put if tryptamite had just referred to it as propylhexedrine, or made an analogy to it as meth with a cyclohexyl instead of phenyl, fully dearomatized. People would know here what propylhexedrine was, or could make the connection between a cyclohexane ring and a benzene ring, much more easily than hexahydromethamphetamine. A lot of us here aren't organic chemists, clandestine or otherwise, and wouldn't understand nomenclature such as hexahydro- tetrahydro- dihydro- etc.
I wonder how many of those internal double bonds that in benzene are delocalized would be required to make the molecule rigid and planar enough for psychedelic substitution patterns to work, because given the conformations of cyclohexane, I doubt propylhexedrine would take to such manipulations with success.
