About the Authors: Karlis Ullis and Josh Shackman

Karlis Ullis, MD, is the Medical Director of the Sports Medicine and Anti-Aging Medical Group in Santa Monica, California and a faculty member of the UCLA School of Medicine. He is an internationally recognized authority on anti-aging medicine and sports medicine. 

Dr. Ullis has recently completed two books published by Simon & Schuster: Age Right : Turn Back the Clock With a Proven, Personalized Antiaging Program and Super-"T", The Complete Guide to Creating an Effective, Safe, and Natural Testosterone Enhancement Program for Men and Women (Fireside Division of Simon & Schuster). He first began developing his theories on anti-aging medicine while at UCLA where he worked with some of the world�s greatest athletes, including Olympic Gold Medallists Gail Deevers, Jackie-Joyner Kersee, Mike Powell, and "Flo Jo" Joyner, among others. When he began applying these advanced anti-aging techniques to patients in his private practice, the results were startling: Middle-aged men and women who had accepted a decline in their health as a "fact-of-life" were re-vitalized - physically, intellectually and sexually.

Josh Shackman, M.A., is the Research Administrative Director at the Sports Medicine and Anti-Aging Medical Group and a co-author of Super-"T", The Complete Guide to Creating an Effective, Safe, and Natural Testosterone Enhancement Program for Men and Women.
