When it comes to increasing muscle mass, one of the most important factors is the HGH or human expansion hormone. HGH is a hormone that occurs as expected in the human body that is responsible for stimulating the growth and cell reproduction. Athletes and bodybuilders typically use HGH supplements to increase their muscle mass and reduce their levels of subcutaneous fat. Natural Methods
While HGH is a natural substance the body produces less and less of it as we age. Around age 20, the body begins to produce about 14 percent less HGH for each successive decade; which may have far-reaching effects on the state of the body. There are many different ways to increase HGH production, some of which do not require additional supplements or large changes.
