In the 1950’s it was recognized that growth hormone was required not only for growth and development in children, but also maintenance of mass, particularly muscle mass, in adults.
Over the past 40 years there has been extensive research into Human Growth Hormone, as well as growth hormone effects in mammals. All of this research has pointed to the fact that adequate levels of growth hormone are required for regeneration and repair, particularly of muscle cells, as well as maintenance of strength, contour and athletic ability.
About 40 years ago it was realized that high protein diets could assist in the development and enhancement of muscle mass, athleticism and improved sports performance. These enhancements were due to the high protein diet providing improved growth hormone levels. Unfortunately a high protein diet can only do so much, however, fortunately, exercise itself will elevate growth hormone levels, so there is a greater return from the right kind of strengthening and other forms of exercise than just the exercise itself. This is a result of improved growth hormone levels enhancing muscle development.
