Prostate cancer is the most common cancer and the second leading cause of cancer-related deaths among men in the United States.  The prostate is a walnut-sized gland behind the base of a man’s penis and below the urinary bladder. Its function is to make seminal fluid, which is the liquid in semen that protects, supports, and helps transport sperm.  Once you understand the risk factors of prostate cancer, you can undergo tests, implement lifestyle changes, or take medications or supplements to help reduce your risk of prostate cancer.

Others purchase HGH products -- or products that claim to increase your body's own production of HGH -- in the form of pills and sprays. Companies that market these products on TV infomercials or online claim they turn back your body's biological clock, reducing fat, building muscle, restoring hair growth and color, strengthening the immune system, normalizing blood sugar , increasing energy and improving sex life, sleep quality, vision , and memory. However, the Federal Trade Commission has seen no reliable evidence to support the claim that these products have the same effects as prescription HGH, which is always given by injection. Taken orally, HGH is digested by the stomach before it can be absorbed into the body.
