We have been using Neprofin AVF and Novequin for the past 7 months and have seen drastic results in one of our performance horses that was injured in her hip area. She lost muscle and was sunk in on one side. After being on the product she has almost completely filled in her right rear hip. Results were so amazing that we started several of our other performance horses on the products as well. As long as these horses are in the rodeo arena, they will be on both of these products.
