Has anyone ever tried these? Have been given some by a body builders runner girlfriend to aid running - dont know much about them really but tried one and they gave me palpatations and then when I went to the gym - I seemed to think I was hulk hogan! Even though im not - so came away quite sore. Just wondered if anyone else has any experience of them - apprantly its a combination of caffine and asprin? Raises metabolism and gives surplus energy...?
Thanks in advance.
