As a biochem major I can't recommend 1,3-dimethylamyamine; it was originally made as a nasal decongestant so it wasn't made as a stimulant.

The thing is are you talking about the street drug Cocaine or the energy drink Cocaine? The street drug is obviously really bad but the energy drink might give you what you're looking for but just have a breath freshener on you because it tastes like raw cinnamon powder mixed with habenero pepper juice the first time you drink it.

If that doesn't work then I would suggest that you try to get your hands on this underground energy shot called Kickin' Energy; it's grape-flavored and although it is kind of pricey it is amazing for a 2 fl oz shot. I drank it the morning of my AP test for Calc and in half an hour I went from dozing off to feeling like I could compete in a decathalon. If that doesn't work then I don't have many ideas.
