Given the confusion, if you are interested in HGH, simply do research outside of a forum. Unlike steroids, there are many documented trials on humans over the past 2 decades.
Simple answers: No you will not get taller. This only happens in children during puberity because they are growing, hence the additional HGH will cause more growth only during that time period.
You are confused by the name. With adults, increased HGH increases protien synthesis, and in general slows the aging process. If HGH made you grow did you wonder why you stop growing as an adult?
In very simple terms, we get older and we age. We get wrinkles and our bones begin to deteriorate. It is a scientific fact that there is a direct connection betweem aging and the face that our natural HGH production begins to decrease at the age of 18.
No your teeth won't grow, that is a fact and I find it dangerous for adults to be on here making comments without a clue as to what they are writing. When did that become ok on here?
Taking HGH will not stop or in any way reduce your natural HGH production.
Above All, please do your own research on the subject. Unlike anabolic steroids, there is an unlimited amount of factual information you can find for HGH. Don't rely on another persons oppinion when you can find the real facts and make an educated desicion on taking the substance.
