To start your horse on Movex we recommend 1 dose per week for 4 weeks. After your horse has finished the 4 week phase, use 1 dose per month. 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!
