Dr. Mark Juhn, an attending physician at University of Washington's Hall Health Primary Care Center and a Husky sports team doctor, says if what arrives in the mail actually is HGH, these people are playing with fire. The commercial claims for HGH are way over-inflated. However, human growth hormone does have medical applications. It's easy to say that you will benefit from something you're deficient in, but if you already have enough, then too much of a good thing can be harmful. Most adults, contrary to the marketing pitches made for HGH, do not suffer a deficiency of the hormone.
Levels naturally decline after people reach adulthood.
Some people take HGH pills to look younger, but Juhn says that may be dangerous. There's nothing more complex in the human body than the endocrine system. It affects how the rest of the body's systems work. It astounds me that people are willing to mess with that. Juhn says no one knows for sure.
