"The day we ordered MYOS, we were preparing to have our dog put down because he would not get up anymore. He had stopped going potty for fear of walking. His muscle tone was all gone. He was in pain and could not walk. Pain meds were no longer helping.

It's now been a month on MYOS and he is jumping for his cookies, has gained muscle where he was all bones and is going up and down steps!

I have to say what a miracle this product was for our dog.  Our dog is 13 years old with Addisons. He no longer needs his pain meds and is a renewed dog."


"Our dog Diesel was experiencing sudden muscle loss and suffering with a heart breaking limp.

I tried MYOS after trying laser therapy, acupuncture and swim therapy with no success.

I am happy to report with the addition of this supplement and continued water therapy that Diesel is almost limp free and running again!"

"I have a 10 year old boxer. Over the past year, he had been steadily losing weight, experiencing muscle loss and weakness mostly through his hind quarters.

After only 2 months on MYOS, he has regained 4 lbs of muscle!

I have used the supplement under my Vet's supervision and checking blood work. My Vet confirmed the muscle is coming back in his hind quarters."
