A little over 7 weeks ago I started my horse on what I thought was Adequan. Turns out it's the Adequan Compound, Acetyl-D Glucosamine. I was a little confused at first about this, because the vet that had perscribed it to me, said it was actually Adequan. She wasn't exactly straight forwarded. I called her up for clarification and an explanation. Anyway, once I found out that actual Adequan is around $60 a month, I decided to just stick with the compound. She said that it is basically the same thing as Adequan, just not as quick to take effect. She told me that many of her clients use the compound and are quite happy with it. Is anyone else giving their horse Acetyl-D injections once a month? Is it working for your horse(s)? What do you think of it? EZ will be getting his first monthly vaccination coming up soon for his mild arthritis.
