    Rated 5 out of 5 by from Helps hold weight on my old performer! I have been using this for over 2 years. My horse is a performer. He is 20 and competes FEI - Dressage. I believe this has helped him keep and build weight and muscle - Thank God!

    Rated 5 out of 5 by from Smart Muscle really helped my horses top line I noticed a difference in my horses appearance within a month of starting Smart Muscle. Great Product!
    Date published: 2016-12-02
    Rated 4 out of 5 by from It works well It works very well for helping to build muscle. My horse likes it, but gets picky about too many pellets in her food, so 2 scoops sometimes seems like a bit much for her. I feel like execising the horses while on this supplement helps them even more, otherwise it seems more like fat builder. My mare is chunkier, almost like a pony though.

    Rated 5 out of 5 by from This stuff really works! My horse has been on this for less than 1.5 months and I've already seen a huge difference! Although my horse has technically moved to a new facility 3 months ago and is on a much better training regiment than she was in the past, Im still sure a large part of astounding improvement is due to this product. So my mare has never been the big drafty type of warmblood; she's more of a dainty lighter warmblood. Despite that, she has developed a beautiful top line, a cresty stallion neck and her quarters are totally filled out. Even my trainer is lost for words my mare's improvement. I am continuing to see results in her top line week by week and its jaw dropping! This combined with well balanced strength training made my horse look like a million bucks!

    Rated 5 out of 5 by from Great Product! I have been using this mainly during the winter, to keep muscle on my OTTB, who is a senior citizen. I found out it's great all year-round to keep him fit, and I don't have to worry about him getting "robby" or losing his top line. Love this supplement!

    Rated 3 out of 5 by from Small difference I saw a small difference in his weight/muscle, but his coat is amazing. My horse is very active but doesn't work hard. Maybe if he was working hard he would have shown more muscle development.

    Rated 5 out of 5 by from Great so far I've already seen a difference in my guys muscle mass! I own an OTTB who was in a hospital for 4 months and 8 months of rehab and his muscle is coming back nicely. We started off on muscle recovery and just swapped to this.

    Rated 5 out of 5 by from Keeping the top line up. I have had my older gelding on this for about a year and its great. He had some trouble keeping weight and muscle on over winterandlast spring just looked pathetic. so i puthim on this and he has been steadily improving each month i see his top line improve.

    Rated 4 out of 5 by from So far so good I'm about half way through with my second month and this stuff Seems to be starting to do the trick. I bought this for a skinny mare who had put on a lot of weight but top line was just not wanting to fill out on her. She hasn't completly filled out but it seems to be helping her move in the right direction. I will be continuing this for sure!
    Date published: 2016-07-25
    Rated 5 out of 5 by from Noticeable Results I've had my horse on this for 3 months now and the results have been great. His coat is shinier, his top line looks way better, and it helps support all of his muscles during increased workload.

    Rated 5 out of 5 by from Awesome product! I was skeptical when I bought this product but my vet recommended a muscle building supplement so I went for it and I couldn't be more happy with the results! My gelding looks fabulous!

    Rated 3 out of 5 by from Smart muscle mass I feel my horse has not be on it long enough to rate yet. My horse has heaves and it takes longer to see results but I'm sure I will be happy all the other products I have purchased have helped her. Without them I feel she wouldn't be doing as well as she is. I have her on the lowest dose of steroids and she is breathing fine. I just have to get some weight on her.

    Rated 5 out of 5 by from Works for my horse I bought this for my Morgan gelding a few years ago and he beefed right up. I currently am using it with my 7yo Oldenburg and she's been having issues putting on muscle but I'm really seeing a difference 6 weeks in. Love this product.

    Rated 5 out of 5 by from Excellent results I bought this to help a couple of my older horses pick up some muscle. In just a couple of weeks I saw a big difference in the way they look amd feel. Very impressed with this suppliment.

    Rated 5 out of 5 by from Saw Improvement in 6 weeks Our chiropractor recommended this for my 24 yr old Dutch Warmblood. I see improvement in his muscles on his back and withers. He tends to get a sore back and this has definitely helped with his muscles. I plan on starting my 18 yr old Swedish Warmblood on it as well. Not sure it's creating muscles but it is definitely improving the condition of the muscles in my older horse and it seems to be stopping the muscle loss that happens naturally at these older ages.

    Rated 5 out of 5 by from Great product. Our horse was in poor condition when we bought him. He received weight gain for almost a year to help get him back to a healthy weight. Once the rest of him looked great, his topline (which the vet told me is always hard to get back in older horses) still needed a little more so I decided to switch him to SmartMuscle. I started to notice a change after about 2 months and by month 4 he had put on enough muscle across his back that his saddle no longer worked. We have a second horse that we also bought in poor weight who is younger so his weight bounced back very quickly, but we put him on this too to support muscle development. I have been noticing his hind end filling out nicely.

    Rated 4 out of 5 by from Happy so far My 2yr old Standardbred Race filly has been on this supplement for just over a month. I have noticed some more muscle definition in her hind quarters and chest. After another 60 days I think I will get the results I am looking for. She eats the pellets without a fuss. Also this supplement did not make her 'hot'
