Human Growth Hormone, Testosterone, Estrogen: Healers or Harmers? Part 1.


Let’s face it, nature wants us dead. We were born to die. That may seem a bit harsh but I don’t make the rules. Can the use of human growth hormone and sex steroids help us delay this inevitability? Maybe.

After birth most living things are programmed to develop physically and sexually, to rise to dominance in their environment, pass on their genetic material as fast and as frequently as they can…then die. The species which masters these simple principles rules the earth. As well they have. I refer to cockroaches, ants and other creepy crawlers. Then comes us, the humans. We lag behind because we are slow reproducers and possess a stubborn refusal to die.

I am imagining most of you nodding your head in agreement as you read the programmed stages of life…develop sexually (yes), dominance (yes, yes), pass on genetic material fast and furious (oh yes, oh yes). Then comes the frown and gnashing of teeth… death you say? Death can’t be part of the plan. How could we be programmed to die?

Scientific support for a natural death wish comes from several angles. For example, there is a suicide gene in our cells. The term for programmed cell suicide is apoptosis. When the genes for apoptosis are turned on in a cell, the cell dies. These genes (some are termed “reaper” genes) are responsible for cell suicide. From another perspective we learn that the machinery for cell repair and replication has a built in limit. After a certain amount of replication the cell machinery runs out of supplies and the cell will die. Together these irreversible features of cells guarantee death.

During the development years (up to age 25 or so) the apoptosis genes mostly serve constructive purposes like removing tissues that stand in the way of growth or to prevent cancer cells from reproducing. The chemical messages of growth and development produced in our endocrine glands (known as hormones) are released into our blood in abundant amounts. These hormones include growth hormone, sex hormones (testosterone and estrogen), and adrenal hormones such as DHEA. After that these hormones gradually decrease and our abilities and physical attributes begin to decline.

The role of growth hormone in the adult remains controversial. Once the bones have grown to full adult size some experts claim that there is no other important role for growth hormone. I disagree. There are many tissues in the body that have “receptors” for HGH so that growth hormone can continue to play a role in maintenance of bone, muscle, brain, immune cells and other tissues. I believe that nature intended “growth” hormones to maintain, sustain and repair the body that it helped create during the development years. Without them the aging process through cell suicide, starvation, or disrepair is unopposed, and decline and death are not far behind.

To cripple the body a good starting place would be elimination of the machinery for making the caretaking hormones. The onset of menopause is the most obvious example of natural ending of the hormone making process. The changes of menopause due to estrogen deficiency that occur in the skin, hair, bone, arteries (arthrosclerosis), are all very well known. Not to mention hot flashes, moodiness and loss of libido which reduce the quality of life. Less obvious but just as critical hormonal declines associated with aging are the steady dwindling of testosterone in men, and the reduction of growth hormone and DHEA levels in both sexes.

The questions before us are whether or not replacement of these hormones will delay aging or improve the quality of our lives.

Important Notice: Hormones such as growth hormone, testosterone, and T3 are prescription drugs to be prescribed by a licensed professional within a doctor patient relationship. Prescribing or using growth hormone for the purpose of enhancing athletic performance, or using these hormones without a prescription is illegal and punished by fines and possibly jail. Metabolism.com and Dr. Pepper continue to support a lively debate about the appropriate use of these medications to help patients with true medical needs.
