yes i use it on my old rodeo gelding. he has a bad hock. tried all kinds of supplements and legend, got his hocks injected and still was hot and swollen and he was SO SORE. Three months after his hocks were done he was still sore, so I started him on summit. He's been on it since May of this year. HE is great! back to work - well ranch and trail work. Feeling awesome.
I went with Movex simply because I can order from the company. It's not a MLM. My mare made the best two runs of her life after two doses. I gave the third dose today.
