What our customers say

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.

Alexia Tsakiris, BVetMed, GDVWHM, CVA, RH(AHG)

MYOS 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.

Dr. Carla Rodrigues DVM, CCRP, CVA, CVMMP

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.

Dr. Cara McNamee, DVM, cVMA, CCRT
