Brain Juice?

Alright. So pimps have pimp juice, health nuts have veggie juice....we, the medical students have what? Brain Juice. Now, this has been used in reference to any substance that we ingest that has some effect (whether percieved or real) on our energy and concentration abilities. It really could just be ground up chalk in a capsule form and believe me, we'll take it if you promise us it'll make us concentrate more, think faster, recall any page of text in any given textbook or just not stare blankly at a professor while we search for an answer or (the usual response) hope that by staring blankly they'll give up and ask someone else or just forget we were ever in the room to begin with. So anyway, I'm considering ordering this Brain Quicken stuff cause they say that I get 110% money back guarantee that ......"BrainQUICKEN is a lab-tested performance product scientifically engineered to quickly increase the speed of neural transmission and information processing (perceptual focus, memory storage, and recall), with a prolonged effect of 2-6 hours following each dosage."......Now seriously, how could I even consider not ordering it??? A fellow medical student was popping them like Tic Tacs while studying for her boards....and, well, she made it to them exam! We don't know her score yet but I'm willing to bet it was fantastic. Hmmmmm, Decisions. Decisions. Obviously the fact that I've never heard of any of the ingredients has no bearing on this decision cause THEY SAID IT'LL WORK. That has to count for something. Ooooooh, brain juice.
