Long ago I tried taking equimolar amounts of powder caffeine, theophylline, and theobromine to see if it was better than an earlier theophylline experiment that just give me sour stomach and a theobromine one that contributed to severe hiccups. It was not like chocolate at all, of course. My final attempt was to add the amounts equivalent to 400 grammes of dark chocolate to a proportional amount of dextrose, with some calcium carbonate, the surface scraped from green M & Ms and catnip. Then with citric acid and a lemon-juice catnip extract. All PO via parachuting or mixing into seltzer. An early attempt at an aphrodisiac when I was still in secondary school. The three of us working on it even had a trade name picked out for our chocolate alkaloids salts-chalk-catnip-green M&M concoction -- the Hershey's Hand Job, which was more to the point than PantChocPon-Pussy Forte or the like.
