The Human Growth Hormone (HGH) is one of the most important hormones in the body, affecting everything from muscle mass to insulin secretion. HGH is secreted by the pituitary gland; a tiny pea sized organ that sits at the base of the skull. Aside from HGH, the pituitary gland also secretes eight other hormones, however, for the sake of this article, we will look at the interaction between the pituitary gland and HGH.
Regulated by the hypothalamus, the pituitary gland has access to both HGH and GHIH (HGH inhibitor) and depending on the state of each individual, it will release different levels of HGH into the blood stream. The largest dose of HGH is found to be released into the body about an hour after sleep, but there are also other factors that can increase or decrease HGH release into the blood stream. A few examples of HGH stimulators are sleep, exercise, and nutrition, while inhibitors can include obesity and high blood sugar.
Although HGH is known to taper off as we age, during childhood HGH release into the blood is very high. One source has reported HGH in adolescents to be around 700 ug/day, while adults secrete around 400 ug/day, a drop of almost 50%. However, cadaver studies have shown that even 80 year old adults still have a significant store of unreleased HGH in their pituitary glands. What causes adults to stop releasing is still a mystery.
Because HGH is known to increase muscle mass, decrease fat mass, and increase bone density in adults, it is currently a well sought after supplement for athletes. However., HGH intake has also recently increased with the general population looking to reap it’s benefits. In the US, HGH injections are only available through a prescription and companies looking to sell supplements are forbidden by the FDA to state that it contains HGH. This is because aside from the many benefits, synthesized HGH has yet to be studied enough by the FDA to ensure that it is not harmful to people who take it without a prescription.
So with all these restrictions, how can there be so many companies out there selling HGH supplements? A quick search on any search engine will bring up hundreds of companies selling HGH as a spray or pill, so what’s up? Well, even though the FDA bans companies from selling HGH in any form to customers without a prescription, it does not ban the sale of dietary supplements which trigger the release of the HGH stores that are present in every adult’s pituitary gland. These companies are not selling synthesized HGH but rather helping customers unlock their own supply. So, does it work? From the looks of things, it seems like it does, but again, customers who are looking to reap the benefits of this powerful hormone should ensure that they do their research, talk to their doctor, and find a source that is both trusted and safe.
