Use this for our female huskie post-cancer surgery, based on suggestion by her vet and after checking results of a University of Pennsylvania study that indicated it had a remarkable ability to stop cancer cell growth. Our dog has a large mammary tumor with an extremely aggressive cancer. Surgery margins were clean but odds of recurrence within six months were considered high. That was nearly two years ago and she is going stronger than ever, with as much energy as she had at half the age. Chemo treatments would have cost much, much, much more and are not demonstrated to be effective in canines. Very, very happy with this product, and the price could not be better. I looked.
