I don't think of these substances as aphrodisiacs because they don't make you horny. However, they can still very much enhance sex.
RC's aside.
Look into Horny Goat Weed. The one from the Vitamine Shoppe is one of the best and not that expensive.
Take 2-3 of them a day, after 3-4 days - just wait and see the difference.
2CD got me definately horny more than once.2C-D also gets people horny, because of the phenetylamines and therefor delicious bodyload you get from it (unless you get visuals on top), so again different people different strokes.
2C-B although this effect does vanish with too much use
You serious?
...sometimes my brain can switch from "mm, beautiful labia" to "ugh, gaping wound" in a matter of seconds.
