This is a 2 part question.
#1 Do pro bodybuilders EVER get off juice? Are they ON all the time? And if they are ON all the time, do they ever use HCG? Wouldn't make much sense to me if you're just going to go back on juice again. To me it would like crashing a car, getting it fixed up and then crashing it again.
#2 If someone were to be on exogenous testosterone (at bodybuilder doses of 300mgs and up per week) for the rest of their life, what would be shut down in their body? Just their testicles? Or would their thyroid also be shutdown? Would their adrenals be shutdown as well?
