We have been using your products for years. My mother’s 34 year old TB/QH cross started on Acti-Flex 4000 years ago and it kept him sound and happy. My 15 year old TB/QH had crappy feet prior to your Hoof Secret, Acti-Flex 4000 works wonders as well. This year we added Gain Weight and holy cow, I love it! He’s finally fat, which is a healthy weight for him. Thanks again for all that you guys do!! We really do love your supplements.
