MYOS Corp Consumer Bait and Switch
The MYOS corporation sells quality products, unfortunately it also failed to honor a 25% Father’s Day discounts on Amazon - though customer service admitted to advertising the 25% discount on the Amazon website as well as other venues. This form of bait and switch isn’t okay as the other sites charge $10.00 shipping. Amazon Prime doesn’t as consumers pay a fee for free shipping. I’m reporting this after giving MYOS customer service repeated chances to escalate my reasonable complaint for supervisor review and response. To be clear, I even have a screen shot where the company admitted they listed Amazon as part of their Father’s Day sale venues then failed to honor their offer.

NO favorable results from Myos Canine Muscle Formula, and a company with suspect, greedy values
We gave Myos Canine Muscle Formula (Vet Strength) a full year, hoping that we would eventually see an improvement in our dog's hind-end muscle weakness. Her condition was muscular, not neurological, and we wanted to believe that Myos might help strengthen her muscles and improve her quality of life.
Sadly, our dog passed away before we could ever attribute any improvement in her rear-end weakness to Myos. Aside from this issue, she was otherwise in excellent health.
Over the course of that year, we spent hundreds—if not a thousand dollars on Myos Canine Muscle Formula. Unfortunately, it was only after our dog's passing that we discovered what we believe to be the true character of the company behind the product, Myos.
When we notified Myos that our dog had died and asked whether we could return one unopened canister of Myos Canine Muscle Formula, for a refund, we were told no. The reason given was that the product had been purchased more than 30 days earlier, making it ineligible under their return policy. I understand and respect that that policy exists for a reason. However, what disappointed us was the company's unwillingness to exercise any discretion or compassion in light of the circumstances. Given the amount of business we provided Myos, over the years, it would have been meaningful if Myos had chosen to make an exception, of a refund, for a single unopened canister. Instead, Myos simply reiterated their return policy—twice. In my opinion, this response spoke volumes about Myos’ corporate values, customer commitment, and company culture. Had this product been purchased through Chewy, a company with which we now intend to concentrate our future purchases, I am certain the outcome would have been different. Based on our past experiences, Chewy would have refunded the purchase, expressed sympathy for our loss, and perhaps even suggested donating the unopened product to a shelter. In fact, CHEWY did just that (and sent us a bouquet of flowers, as an expression of their sympathy). Myos, unfortunately, demonstrated a very different approach, they quoted cold-blooded rules.
What did we learn from this experience?
First, we will not do business with Myos again.
Second, we continued purchasing Myos Canine Muscle Formula, year after year, because we hoped that, eventually, we would find the right dosage or duration of Myos Canine Muscle Formula, and finally see meaningful results. Looking back, that expectation may have been unrealistic. Most importantly, we learned that Myos is not the type of company that, in our experience, chooses compassion over policy when faced with exceptional circumstances. We leave as former customers of Myos, feeling disappointed and undervalued, and never to return to Myos, again.
One final note: if you have a senior dog, I encourage you to consider enrolling your senior dog in the Dog Aging Project, a remarkable research initiative led by the University of Washington and Texas A&M University. The project is helping researchers better understand aging, health, and longevity in dogs. Given that many of Myos’ customers are owners of senior dogs, it would be wonderful to see the company support efforts like the Dog Aging Project by contributing a portion of its proceeds to canine aging research. Such a commitment would demonstrate a level of community engagement and customer-centered values that, unfortunately, we did not experience, firsthand, from Myos.

Customer support is poor
Customer support is poor. It took me 5x to change my credit card. Now my dog is no longer here and I cant cancel the subscription. It also stopped helping him when he was using it. I notified my vet and PT that treated my dog.

My horse won’t eat it
My horse won’t eat it. And there is no email on the website to get my money back even though there is a 30 day guarantee.

A month later, paid but not received
My order was shipped on 10/8/25. On 11/3/25 I notified myospet. They told ME to file a report with USPS. Well, only the shipper can do that. So I had to again email their lazy customer service who then said they would re-ship. As of today, I have received no tracking information on the order I placed 10/3/25. I am asking my vet to recommend a new product, one we can get sometime before my dog passes away.

They keep emailing me over and over…
They keep emailing me over and over despite unsubscribing multiple times. Their product also made my cat sick.
