MYOS Fortetropin® is a groundbreaking, all-natural muscle health supplement clinically shown to help build muscle and improve mobility in dogs and cats. Made with USDA fertilized egg yolk powder in the US.
We have had great personal success with MYOS with our own 13 year old malamute girl Sacha. She has been on it for 2 years and still goes on 2 mile walks every day and is still doing stairs!
