Has anyone ever used tandem oral joint supplement? I had the vet out yesterday for fall shots and we got to talking about joint supplements and she recommended this one. (He does need injections but as we are nearing end of season I was going to do early next year before we start running hard) I was also going to do adequan beginning of season as well. 
Horse is 15 years old and has just started running this hard. But he was bought through a horse trader so I don't now his background. Thanks in advance
