How can i produce more human growth hormone (hgh) in the body?

Sleep and good diet: You may be able to produce more natural growth hormone from getting enough rest and eating a good diet, but this will not change your genetic growth potential (if your parents are not tall, then you won't be either). If you are concerned about growth hormone deficiency, see your doctor and get evaluated. Too much growth hormone is dangerous but only a tumor will cause your body to make too much.
