As far as OTC diuretics go, dandelion root is a good mild one, but Universal Nutrition's Arbuterol is absolutely sick, especially at the recommended max dose. I'm serious in only a few days it will have very noticeable effect and you piss like a race horse on it. Last time i took it, i took the max dose for three days 3 x 3 caps and after that dropped the dose to 3 caps once per day and looked pretty good at the time, i tend to hold water extremely easily so maybe that's why it worked so well on me, also it's very cheap...
