What Are Growth Hormones?

Human growth hormone (HGH), or simply growth hormone, is a hormone that does exactly what it sounds like -stimulates growth and regeneration. More specifically, growth hormone is a peptide hormone, which means that it’s made up of a large number of amino acids that form a long single-chain polypeptide. In the human body, growth hormone is produced and released by somatotropic cells found in the anterior pituitary gland  – more on that later.

The term ‘growth hormone’ or ‘human growth hormone’ can refer to hormones of two different types. The first is known as ‘growth hormone 1,’ or somatotropin – which is produced naturally in all animals. The second type is the synthetic form of somatotropin, known as somatropin, or more commonly by its brand name – Humatrope.

Growth hormone was originally discovered nearly a century ago, and isolated (in the form of somatotropin) in the mid 1950s. Since then, scientists have been astounded by the many benefits of HGH, and its many modern day applications. To this day, science continues to reveal additional uses for this wonder protein.

Although the human body produces HGH naturally, its levels gradually decline as we age. In males aged somewhere between 20 and 30, a normal level of HGH would be indicated by approximately 15-20mU per litre of blood measured at any given time3. Studies show that this level drops by about 25% every year, meaning that by the time you’re 60 your body is operating at only 25% of the original capacity. If our body didn’t have this so called limitation, and level of HGH held steady throughout our lives we would grow several inches taller, have more muscle mass, and very easily live until we’re about 1401.

For that reason, growth hormone is often used in modern medicine to help treat disorders and conditions that involve, or stem from, a growth hormone deficiency in both adults and kids. Amongst much else, growth hormone is used to encourage growth and development in children. Additionally it is used to help regulate bodily fluids, fat metabolism and heart function.

While we still don’t know everything about the growth hormone, but there is a lot that we do know. For starters, we know that there are three ways to elevate levels of HGH naturally within the body – training, rest and nutrition. Implementing a well thought out training regimen, proper nutrition and adequate rest will help maximize your natural potential. HGH is released in pulses throughout the day – with peaks in secretion being about 3 to 5 hours apart, largest of which occurs around an hour after falling asleep.
