"600mg of weekly testosterone administered for 10 weeks, without any exercise, has on the average increased men's fat-free body weight by 4.5%, their strength by 10%, and their muscle area by 6% (quadriceps) and 12% (triceps). The increase in fat-free body weight was greater than that of a control group who took a placebo and performed exercise (2.7% increase). No negative side effects were noticed."
