Human growth hormone or (HGH) is a substance that is produced in the body by the anterior pituitary gland. It helps regulate metabolism of body fat, and is key in repairing muscle and building new muscle. Bodybuilders have used HGH as a way to maintain muscle mass, and increase lean muscle mass.

There are many ways to naturally increase the human growth hormone in your body. One way is through exercise, intense workouts stimulate the body to make more HGH. High intensity sprinting has recently been found to stimulate the growth of HGH, and the key word here is high intensity. Exercise needs to be strenuous in order for the increase to be significant. Sleep is another way to stimulate your body's production of this hormone. Getting at least 8 hours of sleep a night will go a long way to helping your body repair itself and in turn make more human growth hormone. Studies have shown that 75% of the body's HGH production occurs while sleeping.

There are supplements that can help stimulate your body to make more human growth hormone. One of the most popular, is an amino acid called GABA or gamma-aminobutryic acid. This amino acid is classified as a neurotransmitter, and GABA has many positive effects on the nervous system. GABA has a calming effect, so it is best to take this amino acid about two hours before bedtime. This supplement promotes sleep, and is said to give people who take it more vivid dreams. Getting a restful night's sleep, as we know, is important for HGH growth, and this will lead to an increase in energy during the day. People who take GABA have reported a marked increase in energy levels. In addition to an increase in human growth hormone, GABA is also reported to aid the body in fat loss. When supplementing with GABA, good results were obtained with 2-5grams a day. For people who want faster results,5-18 grams works well. There are no side effects from taking this supplement, however, some users reported a slight tingling feeling and a slight increase in heart rate after taking GABA. This does not usually last long, and is mild.

Human growth hormone decreases as we age, so using a supplement to help stimulate it's growth is a good idea. It will help your body to rest better, increase metabolism and help increase the body's lean muscle mass.

Another possibility would be to use Sytropin.
