Amplify is a nutritionally balanced high calorie supplement which provides needed fat for building and maintaining muscle and weight on your horse. I’ve found it to be an excellent product to help with the top line and use it faithfully on hard keepers and mares needing a little extra to keep them looking good. It’s already in many of the Purina feeds but it helps to be able to add a little extra! Big fan and have used it since it came out.

I am excited to see the results of Amplify!!

I think I have found a new supplement for my senior Arab gelding who has issues holding his weight in the winter. He gobbled this stuff up and I did an experiment and fed it to him alone with not grain. He will thought it was steak and potatoes. I am really anxious to see if he comes out in the spring better than he did last spring. Last winter was hard on him and he ended the winter a little too thin. My vet said to feed him a high fat grain. I found a higher fat grain but I thought he could benefit from benefit from a little more fat. With Amplify, I can get good amounts of fat without the volume of adding extra grain from his present feed. Sometimes I wish we could review these products twice, after we have seen the results after a few months. I think I will buy Amplify again!

Amplify Weight Supplement

My horse is a giant Percheron cross and is much more active then he has been for the last several years after moving to a new location and he was dropping weight despite increased grain and hay so I started him on a couple of different weight supplements to find the right one. After trying Amplify there is no other supplement I will give to him, I even added a 50lb bag to my monthly autoship because he absolutely LOVES IT! He would eat around all other weight supplments but not this one - this one is the real deal!

Good supplement for older, hard keepers.

I have four older retired show horses. They are now on pasture, grass hay, alfalfa cubes and Purina Equine Senior. The older purebred Arabian mare is 28 and is not aging well. I decided to give this to her in addition to her regular diet based on the recommendation of my large animal veterinarian. I'm hoping she will put on some weight but minimally stay happy and healthy and not loose more fat.

The pro-Horses like the taste and it has great fat content. Great for horses needing a bit extra fat. Con- if have an underweight horse the amount needed to be given would not be cost effective. I would suggest a good senior fat content like pro force And no additional supplements needed. But for just maintenance or for the winter Amplify is one of the best
