Vet Testimonials
It is hands down the best product I have added to my pharmacy, the clients and patients love it. It has surely helped me change lives. I have seen muscle improvement in extreme muscular atrophy cases that I did not even expect to recover fully. I now have it on auto ship because it is my most asked for product by clients.
Dr. Carla Rodrigues
There are other products in the Equine market that address muscle, none work as good as this.
Geoff Vernon, Equestrian Sports Veterinarian
As soon as we learned about MYOS we knew we needed to carry it at our holistic practice and start our patients on it. We have seen wonderful results thus far, especially in our senior pets who are experiencing muscle wasting.

I started recommending MYOS a few years ago when my focus shifted entirely onto rehab, and have been very happy with the results. We use it for dogs of all ages and sizes. MYOS has become a vital part of our rehabilitation toolkit.

- CRCarri R.Verified BuyerReviewingCanine Muscle FormulaI recommend this productRated 5 out of 5 starsMy 19 yr old dog
A year ago, my 19 yr old dog started using a wheelchair full time. He had been ill and was totally paralyzed in his back legs. His front legs had atrophied (muscles got skinny) due to his previous illness. A dog wheelchair group on Facebook suggested the Myos Muscle formula. It really works. Lucky has regained his muscles in his front legs and can propel himself in his wheelchair. Lucky is also a very picky dog. He has been all his life. But he like the flavor of the powdered Myos Muscle formula. I only write reviews if I truly believe in a product and have first hand experience using it. I hope this review can help someone else's fur-baby.

My 12-year-old standard schnauzer has bladder incontinence when she was only 6 years old. She now has none. She's still very active and shows no sign of slowing down! I also add special amino acids to her daily diet to boost the effectiveness of the Myos Pet. Her veterinarian is very pleased!

This is a great product and has been a valuable regime in my dog's meal supplements for development of her muscles. After her TPLO surgery in early 2025 this was recommended by the surgeon and rehap vet and it helped advance her strength and agility.... she's on the twice a day regimen and as she continues to age, this will be a lifeline to ensuring her quality of active life.
