Isagenics
I think you may mean Isagenix, and yes, I've used it. I became a distributor, also. They are my number one tasting shakes, it is SO good, and tasted like ice cream when I would make it with water, ice cubes, blueberries and the vanilla powder. At the time, about six years ago? I was training for a half marathon and a triathlon, and I used their products religiously. It is cheaper to become one of their associates if you're going to be using a lot of it. We made some cash. Other than that, it basically is just a MLM business. :)
