"I've known Julian since his rookie year and he is a phenomenal athlete who takes his training seriously-it's disappointing to hear today's news," trainer Alex Guerrero said in a statement. "Elite athletes sometimes work with multiple coaches and health professionals as part of their training. Here at our facility, we take a natural, holistic, appropriate and, above all, legal approach to training and recovery for all of our clients. And anyone who would suggest otherwise is irresponsible, and just plain wrong."
