Dr. Smith Johnston, MD, MS, is a leading expert in space medicine with more than 25 years as a NASA Flight Surgeon, where he cared for astronauts, operationally supported over 25 Space Shuttle and 2 International Space Station (ISS) missions.  As Johnson Space Centers Aerospace and Occupational Clinic Medical Director from 2015 to 2019, he oversaw astronaut medical standards, fatigue management, and human performance programs. He retired NASA in 2019 and became the first Chief Medical Officer at Axiom Space, guiding crew health and readiness for private astronaut missions. In 2023 he left that position and now consults for numerous advanced medical technology and preventive medicine companies, and is a professor of Aerospace Medicine at The University of Central Florida, Aerospace Department of Medicine.

"I believe the Muscle Code formula shows great promise for augmenting and extending human performance and longevity, and especially in our aging populations. It’s what I use and what also recommend to my active and retired Astronauts and my earth bound patients."

Dr. Robert Wolfe, a leading researcher in muscle metabolism, has spent decades uncovering the power of amino acids in human health. With a career rooted in clinical research and physiology, he became particularly intrigued by how the body repairs and builds muscle—especially in aging populations and athletes. His research led to a groundbreaking discovery: essential amino acids (EAAs) play a far more critical role than previously thought. Unlike complete proteins, EAAs could stimulate muscle protein synthesis rapidly, even without exercise. This had profound implications—not just for body builders, but for older adults losing muscle mass, patients recovering from surgery, and anyone looking to improve recovery and performance.

"As both the inventor and a committed daily user of Muscle Code, I rely on it to keep my energy strong and my muscles performing at their best. The amino acids in Muscle Code help me stay energized, support my muscle strength, and recover smoothly so I can keep moving without slowing down. It’s the formula I trust—because I created it to truly work."
