As we get older, we all experience a steep decline in growth hormone levels. After the age of 30, growth hormone levels drop by 15% on average for every decade of life. Remember the seemingly endless energy you had as a teenager? Well this youthful vitality is due in part to abundant growth hormone production and release by your pituitary gland. During puberty, males release an average of 150 nanograms of growth hormone daily for every kilogram of bodyweight. This amount settles to about 25 nanograms per kilogram a day at the age of 55 - an 83% reduction in daily growth hormone levels. What this means is an increased body mass index due to higher body fat ratios, reduced muscle mass and strength, decreased bone density, and poorer lipoprotein (cholesterol) profiles among other things.

Like many aspects of the aging process, decreased growth hormone production is usually asymptomatic at first with its ill effects not becoming apparent for some time. Up until recently, the only option to replace growth hormone came in the form of exogenous (from outside the body) human growth hormone (hGH). However, besides being illegal for the purposes of anti-aging, hGH has a whole host of unwanted side effects that most people would rather avoid. They include an increased risk for tumor growth, heart disease and diabetes. These major side effects are commonly attributed to the fact that when you use hGH, levels of growth hormone are unnaturally high throughout the entire day. So what can you do if you are feeling the physiological and psychological effects of aging and want to reverse the hands of time by increasing your growth hormone levels? 

If you know anything about hormones then you likely know that they are quite easy to throw out of balance. That is why sermorelin, and other growth hormone releasing hormones (GHRHs), are so safe and effective. Sermorelin stimulates the production and release of your own growth hormone, in a way that complements your natural biological rhythms. Usually, growth hormone is released in pulses throughout the day, with the biggest pulse coming just before you usually go to bed. Sermorelin stimulates the production of growth hormone in your pituitary gland, allowing for your deeply embedded feedback loops to facilitate or stop production as necessary. So now you know how it works, but how well does it work?
