I’m not familiar withe the product brands you are taking, but you should do this. Look at the ingredients label. The ingredients should indicate one ingredient only. That ingredient should be “green coffee bean extract” and the label should also indicate the chlorogenic acid level. The chlorogenic acid level should be at least 42%. Look at this label to see what an authentic pure green coffee bean extract label should show. See here http:///green-coffee-extract/buy-green-coffee-extract/ . By the way, this excellent green coffee, called Perfect Green Coffee, can be shipped to Trinadad, .
