    My horse didn’t eat his grain for a month because I tried to start him on a different supplement – picky eater doesn’t even begin to describe him! I started him on the Performance Builder while at a horse show, and he ate every kernel of food and licked the bowl clean! In the 3 weeks he’s been on the Performance Builder, he’s gained all the weight back he lost from the previous month and then some – all while at a horse show!! He’s finishing every meal & I can see a positive difference in how his topline is building. I couldn’t order more fast enough!!

    Love this stuff! My draft mix was losing his top line and muscle in his hind end. Within a month he has more muscle tone and has filled out a bit as well. True to the claims…it has not changed his temperament!

    Great product! Worked wonders on our 18yo paint that hadn’t been worked in a few years. Not only did he muscle up, his coat shined up too. He looks and feels great!

    This is an amazing product I use it on my racehorses and thought I would try it on my OTTB that is an extreme hard keeper and oh my goodness you would not believe how much he has progressed…..

    I train thoroughbred racehorses. I started my 6 year old thoroughbred on Finish Line Performance Builder 45 days ago. The difference is absolutely amazing! More stamina training and swimming. Definition in muscle mass and tone. He has finally turn the corner in his training. Very impressed with the overall focus and attitude he has now. If you feel your missing something in your training and feed regime add this product. Definitely a must have in any racing or performance stable.

    Loving over all results. An ease of feeding with other finishline products!

  9. Leah Arledge

    We are giving this product to our 27 y/o Quarter Horse Stallion War Cal. It has made a huge positive difference in his appearance and his energy level. Hence I ordered an additional supply after the “free “ trial product.

  10. Leah Arledge

    Delivered fast. Corrected the invoice to credit the farm tax. Working good on our 28 y/o stallion.

    I was sent a sample and asked to try it. I was quite skeptical as not usually a believer that this type of supplement could make a difference. I was wrong! What a tremendous difference in my horse. He looks amazing! I am extremely happy with this product. So much so that I put more than half of my barn on it!! Not only do my horses look amazing but they’re healthy happy and feeling great. I could not try it when sent as was winter and downtime but now with spring I gave it a skeptical shot. Glad I did!! Try it and turn yourself into a believer.
