Full Description


Simple. Natural. Proven. MYOS uses a single, all-natural ingredient called Fortetropin®. No additives or artificial ingredients. Fortetropin® has been shown in multiple clinical studies to accelerate gains in muscle mass, improve mobility and enhance recovery from injury.

Veterinarian Recommended. Veterinarians reported that older dogs engaged in more physical activity after consuming Fortetropin® and resumed certain activities that were thought to have stopped because of age.

100% Safe. Not only is MYOS safe for your dog, but it's safe for you too. We wouldn't feed our dogs something that we wouldn't be willing to eat ourselves.

Fortetropin® is an all-natural bioactive composition made from fertilized egg yolks that is processed using a patented process which preserves its biological integrity. Fortetropin® contains various molecules that are clinically proven to build and support muscle health for optimal physical performance, mobility, and vitality. Read a case study about it here.
