I started to see improvement in my gelding within two weeks. He has been suffering from ulcers for some time and nothing else worked. After wasting money on other feed thru treatments I stumbled upon this website while looking for an alternative. I love the granules. You can put them right on top of the grain and they eat it. This is much more affordable than pasting (which not all of us get to the barn every day) and can still be given every day.
