Fantastic Weight Builder Product!!
Absolutely love this stuff!! I have a Belgian that has Lymphoma and had lost a substantial amount of weight. The vet put him on some steroids and a weight gain supplement that was more of a vitamin oil. When that ran out, I searched for something to help him gain his weight back. I was feeding him his feed, Strategy, and beet pulp along with alfalfa hay. Then I added the Pennwoods Body Builder 4000 and oh wow!! What a difference it has made!! He is looking soooo fantastic and has energy!! I am only feeding him the lowest dose since he’s not working anymore. Now I’m thinking about putting his shoes back on! He has so much energy and is feeling so much better!! I have read that some horses don’t like the taste, well, mine loves it! A bag is lasting longer than other products I have used for weight management as well! Again, I love this stuff!!! Thanks Pennwoods!!

Good weight maintainer for older horses.
I feed two scoops to all my horses young and old. I add it to beet pulp soaked in warm water. Their hair coats, hooves, and body mass have improved and stay steady.

Zero improvement
Easy to use with scoop provided and seemed palatable as my horses did eat it. Unfortunately after 1 bag and 2 scoops everyday, the horse showed zero improvement. Disclaimer: horse has been seen by a vet and had his teeth done.

Great product
I have now use this product on several of my horses that needed to put on some weight. I used it also while they were in training and it really brought out the shine in their coat, better hair, weight needed and also muscle tone.
