Illegal application of HGH by athletes

Human Growth Hormone (HGH) has been originally developed for clinical purposes. This product is recommended to cure children with growth disorders and adults that suffer from deficiency of growth hormone and associated health problems. But this medicine is often abused. A lot of weightlifters and other sportspeople take this preparation for athletic purposes. Under laws of some countries, including the USA, purchase and intake of this preparation for non-clinical purposes are considered to be illegal.
However this product is illicit without any prescription, it is not difficult to obtain it. This drug is widely available online. Moreover, steroid dealers sell this drug. Since the price is not increased, many persons have possibility to purchase it.
Those that use HGH illegally abuse also other products. They are not limited only by illegal usage of this preparation. Which medicines are also administered by consumers of HGH?
Certain scientists decided to conduct a research related to illegal usage of HGH. They enrolled 230 weightlifters aged 18-40 into the research. The specialists could find out that the most of these weightlifters applied not only HGH but also anabolic-androgenic steroids and insulin-like growth factor-1. Moreover, many of them used recreational drugs, such as cocaine, ecstasy, etc.
Which dangers are faced by those that take increased measures of HGH long period of time? Unluckily, undesirable reactions caused by enhanced doses of this drug are not studied sufficiently because physicians usually don’t recommend enhanced measures.  High doses are commonly used by those that use this medication for performance-enhancing effects. But it is known that application of increased quantities during prolonged period of time may cause serious unwanted effects. This preparation may have negative impact on different systems, including endocrine, respiratory, cardiovascular, etc. It is important to be very careful because increased dosages of this drug are associated even with cancer.
