Dr. Walker is a serious academic scientist specializing in antiaging research and HGH replacement therapy. He believes Human Growth Hormone (HGH) to be one of the most beneficial antiaging substances available, based on its ability to reverse many age-related changes in the body – this does continue to be a controversial subject, however.
Dr Walker founded the Scientific Aging Research Academy (SARA) and has spent a large amount of time studying the role of GHRP (Growth Hormone Releasing Peptides) in slowing down aging.
