This is really making a difference in my 20 year old jumper.
He acts like he's 14. I use a lot of Summit Animal Health products. So if you haven't tried any of Summit Animal Health products give it a try for your horse or dog. I believe in them!!

Great so far
I am working on my bronze medal with my heart horse. She’s an 18 year old warmblood mare. We’ve competed in hunters for the last decade and stated on our dressage journey 2 years ago. We’ve had some stressors (barn move) and got a little discombobulated. We are doing so great now! We are working hard and making great strides! I started her on Muscle Builder a little over a month ago and I really believe it’s making a difference. She is at her peak right now! She’s so strong and willing. Very happy so far!!

PPID Mustang mare 19 diagnosed last year. Noticeably losing top line and I’ve had great success with Summit products( hoof strength). I’m well into the 2 month time frame and beginning to see a difference. I’ll send pictures in another month for visual improvement. Thank you Summit!
