This is a natural formula product, which is very good for calming horses that are nervous and anxious when you need to improve focus. During high intensity exercise the stress hormone cortisol is released and high levels of cortisol is linked to fatigue, mood swings and depression. It is not subjected to herbs, sedatives or any banned substances and will not sedate the horse like many other products. With this you will have all the energy but none of the nerves. The easy to use syringe allows for individual dosing as needed.
