At first 2-FA would come to my mind, then 2-FMA, 3-FPM, and 4F-MPH.
4-FA goes IMHO more in the direction of an empathogen, like MDMA.
I claim not that this is the truth. As this is just what got manifested into my mind at the current position in time on this physical plane. So please feel not offended by anything I say.
