Dude, you probably know that already but I'm gonna say it anyway: the "intra-oral" part is just smoke for the FDA guys, in actuality you're supposed to take it intra-nasal. Look at the shape of that pump and then look at a real intra-oral spray (like something for astma). They look nothing alike! The thing is somewhere in that law that separates supplements from drugs it is specified that the delivery has to be oral. Speaking of which; I don't know how the trans-dermals got thru, there must be a loophole...
