To start your horse on Movex, we recommend 1 dose every 4 days. After your horse has finished the startup phase, use 1 to 2 doses per month (complete instruction sheets provided with each order). Each vial contains a single 5ml dose (250mg of Chondroitin 4 Sulfate suspended in sterile water adjusted for PH 50mg/ml) to be administered intramuscularly in the neck. Wondering if Movex is right for your horse? Buy two doses to try it! You should see results after the second dose.
