The Human Genome Project identified approximately 40,000 genes that
dictate every aspect of human physiology including height, eye color,
enzyme activity, susceptibility to disease, capacity to gain fat and
muscle, and athletic ability.
British muscle physiologists, led by Geoffrey Goldspink, identified a new anabolic chemical called mechano growth/repair factor (MGF) that is produced by the same gene that makes IGF-1 (another important chemical that stimulates muscle growth). Following weight training the gene produces MGF, which jumpstarts muscle hypertrophy. They found that a single injection of the gene into a muscle increased its size by 25 percent in three weeks. IGF-1 and growth hormone are powerful anabolic agents that are popular with bodybuilders and strength athletes. MGF has the potential to be even more effective as a muscle-building drug and could be easily stimulated using gene doping techniques by graduate students with knowledge of genetics and muscle biochemistry.
