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.

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.

I make my own food for our two Mountain Cur hunting dogs. They are now seniors & each has had surgeries for various maladies. More than ever I want to insure they’re getting enough protein. Their surgeon recommended your products & we haven’t been disappointed. They are still very active & playful. I’m confident Canine Muscle Formula is helping maintain their health.

My senior dog is allergic to yeast so any product with yeast gives him HORRIBLE rashes all over his body finding this product was perfect and he’s been able to hop off the porch steps with a bit more ease. This is just a month of taking so still need to continue to see it work properly .

I won a door prize of Myos Canine Muscle Formula and have been totally impressed at Gracie’s increase in lean muscle mass, energy and stamina, so I ordered another canister and have just broken in to it. Besides Certified Pet Therapy Dog, Gracie is also a Human Remains Detection, Search and Recovery K-9. The two videos included are from our weekly trainings. Definitely can see the results. Thank you for a great product that actually does what it is advertised to do.
