    Rated 4 out of 5 by from Overall improvemet I bought this over a month ago and noticed an improvement in my horses muscle tone, tolerance to increased challenge, improvement in transitions into canter, and has more forward movement.

    Rated 5 out of 5 by from Saw results in 1 week. These pellets ate amaing. I turned my hard keeping Arabian Gelding into a Stallion. He looks absolutely amazing. I have added a photo to prove this stuff works.

    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'

    Rated 5 out of 5 by from Great product! Bought this for a 22 yr old Tennessee Walking Horse who had lost a lot of her muscle tone and weight. A little over a month and I'm already seeing a difference! She still has a long way to go, but I think this product is working great!

    Rated 5 out of 5 by from Worth Trying! I tried this on a big warmblood that has always had weight issues and never seems to carry much muscle along his topline, no matter how much work he gets. I admit I was skeptical but with SmartPaks great policies, I figured what the hey! Within a week I was noticing a difference. His weight is better and so is his topline. I couldn't be more pleased. And I can't be entirely sure, but I swear he seems happier! I don't think you'll regret giving it a try.

    Rated 5 out of 5 by from I started my 8 year old thoroughbred mare on this product about 5 weeks ago. When I got her several months ago she was underweight with very little muscle. With work and good nutrition, her condition improved, but she was slow to put on muscle. Within 2 weeks I saw a tremendous improvement in her musculature, and after 5 weeks she has shoulders and a hind end like a quarter horse! This product worked for us.
    Date published: 2016-04-06
    Rated 5 out of 5 by from It works! I have been using this product for about 6 weeks. I give it to my mare, who is coming back into work after foaling. There has been a transformation in my mare. I ride her for 30-45 minutes 5 days a week, and after my ride I give her the aminos, which she eats out of my hand like a treat. She is developing muscles in all the right places. Her back is getting broader, her neck is filling in in front of her withers, and her shoulders and haunches are getting more muscular. She looks fabulous! Her back is broader now than even before the baby. I am very happy with the results I'm seeing!

    Rated 5 out of 5 by from Really noticed a difference I started my pony on this about a month ago and have noticed a huge difference in his muscle mass starting to form. He was lacking in muscle mass even during show season so we decided to try this before training even started and have noticed a change already.

    Rated 5 out of 5 by from I have a young horse again! I purchased an almost 18yr old Friesian mare in Dec 2015. She had been out of work almost a year and a half when I got her. Initially, when she came to me, she was fat, but after putting her in a 5 day a week riding schedule, the fat quickly melted away and I was left with a hollowed out horse with almost no muscle mass. In January, I started her on the Smartflex Senior supplement to help with her joints and any stiffness. In February, after going through all the rave reviews, I decided to try the Smart Muscle Mass supplement as well. Today, my 18 year old horse is like a young horse again!When we first started doing lessons with my trainer in December, 45 minutes of walk/trot had this mare panting like she was gonna fall out. On Jan 30th, we did a clinic with a GP rider. He asked to see our canter, and despite my best efforts, I could not get this mare to canter to save my life! Today? I simply have to put my outside leg back and off we go!She's gained substantial muscle, stamina, and strength on these two supplements and I've watched her become stronger and more supple everyday and she's only been on the muscle mass roughly 6 weeks now. Seeing the change in my horse is simply remarkable!

    Rated 4 out of 5 by from So far so good! My mare has only been on this for a few weeks but we have already started noticing the build up in muscle. Nothing huge right now, which would be alarming if there was, but definitely starting to see the definition in her butt and shoulders.
    Date published: 2015-11-26
    Rated 5 out of 5 by from Great results! I bought this a month ago and my horse looks great. Thunder came to us as a rescue and we found that he will not eat powder supplements. We struggled to put muscle on him for 2 years. He loves the pellets and now after only a month he looks amazing.

    Rated 5 out of 5 by from Work well and fast I had a mare that wasn't building muscle well and we had a show coming up in 4 weeks, I used this product and saw results as fast as two weeks into it. Very nice product.

    Rated 5 out of 5 by from Really Works! I added this to my horses smartpak a month ago just because he wasn't filling out quite like I wanted. He has been in the same amount of work with no change in feed. The difference is amazing already! He is now more filled out over his top line and his hind end is noticeably better. Thank you smartpak!!
