[QUOTE="Blackhawk, post: 250446, member: 16042"] Endogenous: made by/inside the body. Endogenous testosterone is the stuff your testicles make. Exogenous: coming from outside the body. Exogenous testosterone is what you are injecting. They are chemically identical, but... Normally, when you are not taking testosterone, your pituitary makes Lutienizing Hormone (LH) in response to decreasing testostertone level in your blood as it gets used up. This hormone signals the testicles to make more endogenous T. When you inject enough testosterone (Exogenous), and levels remain high enough, there is no reason for the pituitary to make LH, and the testicles do not receive the signal, so they do not produce T. Taking exogenous testosterone shuts down your body's endogenous testosterone production. In this circumstance, Working out does nothing to boost your natural T. Working out will not cause the pituitary to make produce LH when there is already more than enough T. Using Exogenous T is the cause of testicular atrophy from using testosterone. EDIT: Not saying that working out is useless! LOL! You should indeed work out, but the reasons are for your health and fitness! Just like eating right, getting good sleep, etc etc are all important for good health. [/QUOTE]
