Even more diet pills..

I am starting to get goggle-eyed over the many different forms of diet pills there are out there and ever more tongue-tied with their names. the latest one I have come across is called Ephedra eca stack and contains caffeine and aspirin (Ephedra Caffeine Aspirin - get it...??)
Now you know right off that some people are sensitive to aspirin, so it is as well to be informed about what these medications consist of. From what I know, caffeine is used as a stimulant to push drugs around the body quicker, so that explains what the caffeine is doing there. There have been restrictions on the use of ephedra/ephedrine in some places in the past so make sure you do your own thorough research before taking anybody's word for the effectiveness of this drug.
