Testosterone is
naturally produced in our bodies, it is a hormone that affects more
then just your sex life, although it is quite important in that area
as well. If you have low levels of testosterone, you will experience
erectile dysfunction, weight gain, loss of muscle mass, depression
and even an increase in potency for cancer. Testosterone peaks at the
age of 30 and for some men, its production in the body starts to
gradually decline, about 1% per year.
