We all naturally produce HGH. It is a hormone secreted by the pituitary gland, close to the bottom of the brain, which helps the cells to multiply and promote the body's development. This hormone produces a protein called insulin-like growth factor 1 (IGF-1) by stimulating the liver and other tissues. In turn, the World Anti-Doping Agency (WADA) says that IGF-1 can cause bone growth and play a key role in muscle and organ growth.
Recombinant HGH is a HGH made from genetically modified bacteria that was originally developed in 1981 to help those whose bodies naturally produce deficiency. However, the evidence that supplementing HGH does contribute to athletic performance is primarily anecdotal.
Recently, researchers from the Garvan Medical Research Institute in Australia published a new study in the "Physical Medicine Yearbook" to prove that athletes have at least some benefits.
The researchers tested 103 male and female casual athletes between the ages of 18 and 40. They divided the athletes into two groups. Within two months, one group received HGH injection and the other received placebo injection saline. Some men with HGH also receive testosterone supplements. Before and after the injection, all athletes were weightlifting, cycling, and jumping to test motor skills.
Two months later, the strength, strength or endurance of the athletes receiving HGH did not improve. The only improvement is the speed at which the athlete sprints on the bicycle. The number of patients given HGH increased by 4%, and the number of men who received testosterone and HGH increased by 8%. The researchers concluded that although the effect was not as extensive as previously thought, the speed was significantly improved.
