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 the real deal! Our bear had lost a ton of weight (BBQ grease incident). We switched to raw food and needed to get healthy weight on his bones. Our trainer told us about MYOS. It has been such a blessing. He looks and feels amazing. After 1 mo, I could see it working, 2nd month did the trick. 3rd month just to be safe. We are gonna try to go off for a month and see if he holds his best weight. If not, we are glad to spend the money for more Myos. He may have a sky high metabolism thus needing the extra support. I'm so grateful for Myos muscle. I highly recommend the product.

Millie was limping on her front right paw from fluid in the joints and what looked to be arthritis. After a couple vet visits, nothing was changing. Fortunately we tried MYOS Muscle Formula & within 2 days, her limp was GONE! She was walking normally and better than ever! So thankful this formula is vet approved & so so healthy for them! It saved us so many vet bills 😅! (Insta: @rescuednreactive)
Was this helpful?MPMYOS Pet2 days agoWow, what an amazing update and AMAZING picture! We’re so glad to hear Millie is back on her feet and feeling better—it’s incredible how quickly you noticed a difference. Thank you for trusting MYOS and for sharing your experience (and Insta!). Give Millie some extra love from us 💛🐾
- KBKimberly B.Verified BuyerReviewingCanine Muscle FormulaI recommend this productRated 5 out of 5 starsGreat Product
My 12 year old GSD and I were in a very bad car accident a few years ago. Although she was in a crate which saved her life, she is now experiencing problems due to injuries sustained to her back. Although she is not in any pain and remains the happiest dog ever, she is starting to show severe neurological symptoms in her rear end. Because I can’t exercise her anymore, I have added Myos to her list of supplements and it is helping to keep her from loosing too much muscle. I’m very happy with this product and would definitely give it to my next dog which I will include as part of their daily diet.
Was this helpful?MPMYOS Pet1 week agoHi Kimberly,
WOW! Thank you so much for sharing your story—we’re so sorry to hear about the accident you both went through, but we're incredibly grateful your girl made it through and is still her happy self. It means a lot to hear that MYOS is helping support her muscle health during this stage of her life. Your dedication to her care is inspiring, and we’re honored to be a part of her wellness journey. Wishing you both continued strength —and thank you for trusting us with her care. 🐾 - DMDanielle M.Verified BuyerReviewingCanine Muscle FormulaI recommend this productRated 5 out of 5 starsWe make sure to never run out!
I’ve been giving myos to my Belgian Malinois for the past 3 years. There have been a few times that we ran out, and I wanted to see if her body condition would change without it, and it did. I can see a change when she’s consistently on it.
We compete in a few dog sports, and it makes me feel better knowing her muscles are fueled properly. Of course she’s properly exercised as well.
Was this helpful?MPMYOS Pet2 weeks agoWow—thank you for sticking with MYOS all these years! 💪🐕 It’s amazing to hear how consistent use has supported your Malinois, especially with her active lifestyle. We’re honored to be a part of her journey in dog sports and beyond. Keep crushing it, team! 💥
