The benefits of growth hormone (GH, also known as human growth hormone or hGH) have received increasing attention from not only the media but the medical profession as well, as a result of studies indicating GH may have the ability to restore a more youthful physiology and enhance the quality of life. However, there is controversy centered on the possibility that maintaining youthful GH levels may actually be harmful in the long run and may result in shortening life span by inducing cancer.
The first foundational objective essential to gaining an insight into these issues is to clearly understand the hypothalamic-pituitary axis. More often than not, we forget the physiological safety mechanisms designed within our systems to protect us. In this case, we refer to the negative inhibitory feedback loop designed to decrease or stop the release of endogenous GH when levels exceed the physiological range. This inhibitory feed back loop plays a significant role in the hypothalamic-pituitary axis and realizing its significance is vital to understanding the advantages of using growth hormone releasing hormone (GHRH) to increase endogenous GH as opposed to using exogenous GH.
This will lead to the discussion of why assessing increases in insulin-like growth factor type1 (IGF-1) as a marker of GH efficacy may not only be unreliable, but a compelling argument will be presented that the practice may be nothing more than the perpetuation of a medical myth. In fact, conclusive data from multiple sources showing that increases in IGF-1 are conducive to the propagation of oncogenesis will be presented and then supported by general physiological concepts, scientific observation and published research.
Finally, the inter-relationship of GH, GHRH, and IGF-1, as well as how each individual component correlates with incidence of cancer, will be thoroughly explained.
