- CHCarol H.Verified BuyerI recommend this productRated 5 out of 5 starsWowza!
Myos is one of the few supplements that I can SEE the improvement. My old dog had a scrawny ****. Now she doesn’t and can again get in and out of my truck. I have a big horse that is older. He’s regained muscle where he needed it. I started taking the human version Yolked as I am losing muscle from aging. Works on me too! My vet and farrier have their older dogs on it as does my farm manager. Great stuff.

My senior Arabian gelding was struggling with muscle wasting and arthritis and is now doing well after being on Myos. I did have to mix it into the grain as he is VERY picky, but I am so glad that I gave it a try as I was strongly considering euthanasia and now he is back to light work and some rehab therapy! (Photo is from him post workout last week!) I have had nothing but good experiences with Myos and am so thankful that it is available

- HBHelen B.Verified BuyerI recommend this productRated 5 out of 5 starsUsing on 7 year old eventing horse
This supplement has made a big difference in my 17 hand 7 year old event horse. He’s definitely put on more muscle and feels stronger. Only negative comment would be I wish it came in a bucket instead of packets as I can’t stand all of the waste. Otherwise, great product!

My horse won’t eat here grain when the myos is in it.
If you have a suggestion of how to get her to eat it, I’d love that- my dog loved Myos and it’s helped him so much
Was this helpful?MPMYOS Pet1 year agoThanks so much for reaching out—and we’re so glad to hear Myos has helped your dog!
For your horse, we understand some can be picky with new additions to their feed. A few suggestions that might help:
Try mixing Myos with a small amount of a favorite mash or soaked pellets to mask the flavor.
Start with a smaller amount and gradually increase the dose over a few days to allow her to adjust to the taste.
Adding a touch of unsweetened applesauce or molasses can sometimes make it more appealing.
Let us know if any of these work—or if you'd like more ideas. We're here to help!
