I just don't want the average horse owner to see this post and think they have to inject their horses because unless you have a serious competitor (thus a market of owners who can afford to continue those injections) you could severely limit the potential sale of that horse.
I would love to see a clinical study supporting this.
I actually attended a lecture last week by a well regarded sport horse veterinarian who claimed that Legend shots really only supply enough HA to support the production of joint fluid for 7-10 days. Contrary to what I had previously thought, he suggested that Legend could be injected up to once a week. I have also read articles supporting the thought that the HA sits in the horse's bloodstream until it is needed and only acts as a buffer to the horse's natural production of HA. The Legend is only put to use by the horse's body in periods of high stress.
The only injections clinically proven to cause damage at this point are steroidal.
