Yes I've used it and have had much success with it. I have before and after pictures of using it on my mare with ulcers on the pyloric region. Night and day difference in just 4 weeks. It was recommended to me by the internal medicine vet that developed this product. If you'd like the pictures message me your email and I will send them to you or I can show you on my Facebook.
ETA - This is the only treatment she was on for the ulcers. I never used omeprazole, ranitidine, or sucralfate. After the last appointment and gastroscope I lowered her dosage on the ReLyne and started adding aloe vera juice. I've read good things on Papaya enzymes so I'm going to start adding that as well.
