Product Overview


MYO-X is a revolutionary myostatin inhibitor that can help you build muscle mass safely and effectively. This revolutionary supplement with all natural actives has been shown in clinical research to both significantly lower serum myostatin levels in test subjects and substantially increase muscle mass and muscle thickness in study subjects who used MYO-X along with only a moderate weight training program.

Clinical Study Reveals MYO-X Significantly Builds Muscle
In a landmark clinical study at the University of Tampa Human Performance Laboratory, MYO-X was shown to significantly enhance muscle growth. What makes this even more impressive is that the test subjects were able to experience these powerful benefits when training just two times weekly for 12 weeks!

Research study subjects were able to:

  • Add Up to 8 lbs. of Lean Muscle Mass.*
  • Gain 4X Greater Muscle Thickness.*

This newest study further supports MYO-X’s role as an effective myostatin inhibitor and muscle builder. In prior clinical trials, MYO-X had already been shown to significantly reduce myostatin, a growth factor protein that limits muscle growth. Scientific evidence supports a correlation between reductions in myostatin and muscle growth.

Backed by more than a decade of investigative research and a number of published scientific studies showing how MYO-X can reduce human myostatin levels.

Clinically tested and shown to suppress myostatin levels in 100% of the human test subjects in a single-dose, acute research study.

Manufactured using a proprietary High Grade Handling process and contains a magnified concentration of 80 proteins, 700 peptides plus many biologically active growth factors.

YO-X: The Next Step in Evolution of Muscle Growth Potentiators

Overcoming Myostatin’s Genetic Limitations

Since the discovery of hyper-muscled animals and humans who genetically lacked the specific growth factor protein myostatin in 1997, scientists have been frantically searching to unlock the secrets behind controlling or reducing this powerful negative regulator for growth. One look at images of the Belgian Blue bull, Bully Whippet dog or other examples of “double-muscled” animals shows the incredible potential that myostatin inhibitors hold. The study of human myostatin-deficient ”mutants” with excessively muscular physiques has helped scientists understand the correlation between myostatin and muscular growth (or the lack thereof). When this negative growth factor binds to its receptor on muscle cells, it prevents muscle tissue from growing. Not only does myostatin block muscle protein synthesis, it also blocks the proliferation and differentiation of satellite cells – precursors to muscle cells.

Real Examples of Myostatin Deficient Effects*

Documented cases of myostatin deficiency in mammals, including humans, display astonishing muscular growth and reduced body fat levels. Researchers have been studying the rare accelerated growth of a German child deficient in myostatin since he was first referenced in the New England Journal of Medicine in 2004, while the tremendous muscularity of the Belgian Blue bull and “Bully” Whippet dog breed are other prime examples of “double muscling” due to the absence of myostatin in animals.*

MYO-X Reduces Myostatin & Increases Muscular Growth+

Myostatin is a potent catabolic limiting factor protein that exists in all of us, and works to limit muscle growth in a genetically predetermined pattern. But thanks to MHP’s MYO-X, myostatin can be reduced safely and naturally. MYO-X has already been shown in clinical trials to significantly reduce myostatin levels in human test subjects. The impressive 8 lb. muscle gain demonstrated in the latest scientific research is good news for athletes and fitness enthusiasts looking to increase muscle mass, and shows that MYO-X is a powerful, one-of-a-kind muscle building supplement.

"I’ve never experienced anything like MYO-X. I believe this stuff has extremely powerful effects."

Brian Shaw
2X World's Strongest Man

"If you’re looking to perform better, you need MYO-X. It was an integral part of my training and nutrition program that helped me win the 2013 World’s Strongest Man title!"

"In my work with elite athletes I have seen firsthand the muscle enhancement impact of MYO-X when used in conjunction with intense weight training. These athletes have made vast improvements in muscle size, strength, performance and improved recovery." – Carlon M. Colker, M.D., FACN, Sports Performance Physician, Inventor of MyoT12®
