The natural production of HGH reaches its peak during adolescence, when our bodies are growing towards adulthood. HGH is primarily released in the pulses that take place in the beginning of the sleep cycle. It secretes from the pituitary into the liver where it is converted to IGF-1 (Insulin Growth Factor 1), or Somatomedin C. IGF-1 is responsible for most of the effects associated with HGH. In fact, doctors measure the amount of IGF-1 in the blood to determine a patient’s level of growth hormone secretion.

IGF-1 Promotes the transfer of glucose through cell membranes as a source of fuel for cells, which is insulin like effect. That is how IGF-1 got its name.

Daily growth hormone secretion diminishes with age. A 60-year old will only produce as little as 25% of someone in 25 years old. The decline of HGH is associated with the symptoms of aging. Grey hair, aging skin, insomnia, mental forgetfulness, osteoporosis, lower sexual desire, increased body fat and more.
