Growth hormone reverses the age-related decline of sexual vigor and performance. And it does this at every level of bodily orginzation , from the cells to the organs to whole systems. At the cellular level , it increases protein synthesis and cell division involved in regrowth of organs. On the tissue level, the anabolic effects of nitrogen retention build muscle mass.

On the hormonal level , there is a direct feedback between the pituitary hormones and the gonadal hormones of the ovaries and testes. In many men, taking HGH is enough to bring testosterone levels up to normal. It is also interesting to note , says Karlis Ullis , M.D. , that growth hormone plays a role in both male and female infertitily, improving the effects of the reproductive hormones in the production of sperm and eggs. “This shows one , there is an enhancement factor and two , it is rejuvinating. It also crosses into the brain and seems to activate the whole nervous system. People report more pleasure , which could be because it sensitizes the nerve endings”.

On a systemic level, growth hormone improves cardiac function and circulation of the blood to every part of the body. When more blood is pumped into the penis , erections are firmer and can be sustained longer. Growth hormone has been shown to increase the HDL cholesterol. In one study , raising the level of HDL cholestrol increased the likelihood of an erection, perhaps by increasing peripheral circulation via the plaque removing properties of HDL. Growth hormone also accelerates the repair of tiny tears in the penis and vessel damages that come from trauma during intercourse, from riding bicycles or other activitys.
