Hey Macro, has Yohimburn ES been known to cause any skin irritations? and what would be your opinion on applying Yohimburn ES and then wearing one of the Neoprene Sweat belts...You know, the stretchy thing that you buy @ Walmart that promotes sweating. I like using these belts...similar to the old female corsett, if you wear it tight enough and long enough, it will actually make the area smaller.
