don't use it man, it's a wee bit too dangerous IMO, beta 3 receptors rather than beta 2...I'm not sure how effective the inhalers'll be either, having never seen it for sale like that, I'd guess it's not that effective...
IMO you should concentrate on your diet, lifting + lots of cardio - I reckon the amount you lose from decent cardio (which you shouldn't do to protect your heart) will be as much as you lose from albuterol...
edit: also...you won't get side effects like the shakes, cramps + insomnia (besides others, these're the only ones I got though) from doing cardio
