Formula 707MuscleMx Equine Supplement, 10 lb Bag – Conditioning Support and Muscle Builder for Horses with Lysine, Gamma Oryzanol, Creatine & OKG

Really helps my 36 year old keep his topline and stay looking his best.

I bought this to replace a lesser quality weight gainer. I also bought a good quality fat source. The two together are definitely doing the trick.Very palatable, my horse loves it. I will continue to buy for maintenance.

Works good on a horse that needs help gaining weight

I bought a rescue horse that was very thin, flabby, and had absolutely no muscle. After just a few weeks of having this supplement added to her feed she has amazing muscle growth. She is also on a weight booster, which helps as well, but this isn’t just weight… it’s muscle in addition to weight. I’m very impressed with her progress and will definitely continue to use this product daily. In addition to the muscle growth, she has also had more energy and suppleness. Highly recommend!

Horses: 32 yr old and 25 yr Olds mobility. Only first month, I do see an improvement. I will get another month's worth and see if it continues to help. So far so good.👍

Giving it 3 stars cuz it came SUPER fast and just in time, but have yet to actually use it, so i dont know if it'll work. But the other reviews sound promising. It smells great and I'm excited to start my young mare on it. Weird nitpick though: it has a typo on the back. It's supposed to say 500-1,000 lbs not 500-*100*lbs. It makes no sense and that unprofessional error alone makes me feel sus about the product i recieved.... but i guess we'll find out. It comes with a cup, so that's really nice.

Helped build up my horses topline. He likes the taste and the price is fair.

I used this on a sales yearling and it helped build muscle.
