I was skeptical at first, but very happy with results. My 11year old mare had gotten buddy sour over the years, and nervous trailering. This project has made her more relaxed while standing in cross ties, and while riding. She used poop at least 4 times in the cross ties. While using this product she doesn’t even stress poop on cross ties anymore. She doesn’t even whinny to other horses when ridden. I haven’t trailered her yet since using the product. Does take about 2 weeks to start working. She is not dull or lethargic.

I love Formula 707 products. I use the calming pellets, hoof formula and the Metastable. Great products.

This is the best formula I’ve used. I feed it continually so it is in my horses system at the proper level. He is not a high anxiety horse, but he travels thousands of miles in a year in the western states on the APHA show circuit. He also gets the digestive formula along with it. I use both just to help maintain a healthy balance for him. In pellet form it is easy to travel with and my horse looks forward to it, he thinks it is a goodie and eats it right up.
