Former Bodybuilder taking TRT and Bodyweight set point theories

In this episode, we have a question from a former bodybuilder who wants to get back to his old form. In doing so, he wants to know if he should start taking Testosterone Replacement Therapy and start under Dr. Rand's supervision. The second question is from a 50yr old male who's been taking Test Cypionate, and trying to lose weight. He wants to know if his bodyweight set point is related to only bodyfat, or does it take into account his muscle mass as well. GREAT physiological questions in this segment!
