Since 1997!

I have been using OPC-3 since 1997 and it is wonderful. Back then there was a short black-and-white video that distributors could use that showed the blood before and after using OPC. Before, clumpy and chain-y, after blood cells separated, white blood cells not stuck in some of the clumps, all flowing smoothly. Six months after starting OPC, I had the opportunity to see how my blood was going under a microscope. Guess what? It was blood cells separated, white blood cells floating free to do their work. I have a testimony that this product does what it is claimed to do.
