HGH is otherwise known as the human growth hormone, and its synthetic form is popularly known as Somatropin. Somatropin is in fact an exact replica of growth hormone. Athletes use HGH, now HGH promoting products because somatropin is illegal, because it helps to build new muscle. Muscle cells are generally determined by genetics. After puberty, HGH declines and muscle cells cease to develop. After puberty, the only way is to increase the size of these cells using weight training. Steroids make the muscle cells bigger by filling them with more water. Therefore growth is extremely fast. But with HGH, the gain is slower, 1 to 2 pounds of muscle every 2 to 3 weeks with proper weight training. The difference is HGH actually develops new muscle cells.
Secondly, HGH increases energy and metabolism. This means that your body is naturally burning more fat and you are able to exercise more and burn more calories that way. You will find HGH at its highest levels in puberty. But as you age and your HGH levels decline, so do your energy levels and metabolism. Providing this supplementation once again brings them back up to speed. And when your body secretes HGH, it also secretes a hormone known as IGF-1. IGF-1 actually forces your body to tap fat reserves for energy rather than the food you consume, leading to significant weight loss, even when you’re not actively working out.
Third, it shortens recovery time. It can strengthen joints and heal damaged tissue, helping your body to recuperate and build more muscle, work out, etc. In all these ways, it has been popularly used by athletes, in some cases in injection form. However, all major sports leagues are now cracking down on users of the synthetic substance, and it has been illegalized by the FDA. So many athletes, professional and amateur alike, have begun to look to HGH supplements, which they are often finding to be more impressive anyway.
