(NaturalNews) The topic of much debate and research throughout the centuries can be found in the seed of an idea: the reacquisition of youthful qualities. The 21st century is increasing past efforts, spending countless dollars on the development of products to help a youth obsessed society turn back the signs of time. One of the most promising developments occurred in the 90's when Dr. Daniel Rudman reported to the New England Journal of Medicine that he had reversed aging through the use of human growth hormone (hGH) injections. Unfortunately, shortly after we learned of its dangerous side effects, most notably insulin resistance, arthritis and heart disease. The most promising research today now focuses on hGH precursors known as secretagogues.
