An introduction to Human Growth Hormone

Understand the basics…

By its simplest definition, HGH (or human growth hormone) is a hormone that is primarily responsible for the growth and development of your body. Growth hormone (GH) is a very important hormone that can influence your health in many ways. It is powerful enough to change the way you look, feel, and function.

What are hormones?

Hormones are substances formed in a type of body organ called a gland. A hormone is then directly carried in the blood circulation to another organ or tissue where it has a specific effect.  In case of HGH, such gland is called as pituitary gland and it is situated inside your skull, just at the base of your brain.

HGH – Mode of action

It stimulates the liver and other tissues to secrete insulin-like growth factor (IGF-1). IGF-1 stimulates production of cartilage cells, resulting in bone growth and also plays a key role in muscle growth. In children, this leads to growth in the length of the bones and increases the child's height. By puberty, however, the cartilage at the ends of most long bones is converted to bone and subsequent action of growth hormone or IGF-1 usually cannot increase their length. Therefore, as per medical evidence, taking HGH injections cannot increase your height after the age of 22 in majority of cases.


HGH – Benefits

The reported benefits of maintaining optimal levels of HGH in the body include:


  • Reversal of common diseases associated with ageing

  • Improved brain activity and function

  • Strengthening connective tissue which reduces the probability of injury

  • Weight loss without any loss in lean mass

  • Reduction of wrinkles by rejuvenating the skin

  • Increasing energy levels and brightening mood

  • Promotion of muscle growth

  • Improved libido

  • Improved lung function

  • Provides immune system support and thymus gland function, and the ability to produce more individual muscle cells

  • Has an “anti-aging” effect


In addition, some individuals also use HGH because they perceive that it is as effective as anabolic steroids with fewer side effects, and is difficult to detect in a drug test. It is being used alone and in conjunction with other substances to induce anabolic effects, reduce muscle cell breakdown and reduce body fat. HGH seems to decrease body fat and increase fat-free mass. However, there is less evidence that these effects translate to increased strength, endurance and sporting performance.

HGH and sleep connection

One of the most critical functions that HGH supports is sleep. That is maintenance of REM sleep or rapid eye movement sleep.  HGH guides you into REM sleep and promotes the maintenance of it. Patients with low HGH levels, often described their sleep pattern as waking up numerous times throughout the night, often unable to go back to sleep.

Finally, human growth hormone is essential to growth and as we age it is critical to repairing.

HGH levels fall steadily in everyone once they reach adulthood. Since we now realize that HGH is indispensable throughout life, it must be considered a vital hormone for maintenance of the adult body. Therefore, achieving or maintaining the optimal or at least normal levels of HGH especially after thirties is crucial.
