http://www.news.utoronto.ca/bin6/060222-2077.asp) and they mentioned the problems associated with yohimbine...and tryptophan is fun (we put some crushed pills in cookie mix once) but it was a special occasion and we wouldn't allow anyone to have more than two... and those are just the ingredients in there that I know. Why not get cocoa powder, some agave nectar and coconut oil and make your own chocolate instead?
