i haven't tried it and doubt i could even get it over here in australia but favourite writers from t-nation.com swear by it so take it if you can...that being said unles your food is spot on it will be useless
just FYI the product is produced by the company that owns t-nation. from what i read many say it works as it makes you sweat alot... i personaly don't believe these stimulators to be healthy.
