The Adequan... there is a loading dose, and then monthly or something I think. I don't quite remember.
Adequan DOES NOT recommend monthly use of their product. It's stated right on the front page of the website.
Adequan is administered in 7 doses, one every 4 days. Then the horse can go injection free for as long as a year, and then you do another round. My horse gets one round pre competition season (march), one round during (may/june) and one round before winter training starts (around mid-december).
Pentosan has a similar injection routine. One injection a week for 4 doses. Then you can apparently do a single booster shot, but I am skeptical.
Your best resource here is your vet. I know my vet won't recommend oral supplements because they plain don't work. As well he doesn't give lots of Legend for preventative. I went from 12 shots of Legend a year to one or two when I switched to him, and switched our generic glucosamine IM to Adequan and started on the "program" or 7 injections per cycle. My horse still x-rays totally clean after 5 years of solid work, and national/international level competition. I attribute that entirely to the program that my vet has my horse on.
