I'm not denying that hormones have an effect on muscle growth. The lack T in women is the reason they don't grow as big as men.
What is in question is whether or not a little elevation for 30 minutes post exercise will cause more growth than no elevation.
No one has proven that it does, and I challenge anyone to provide a study which shows this. For all these years that people have spoken about the neuroendocrine response, the fact of the matter is that its hypertrophy enhancing effects have been a mere unproven assumption.
Furthermore, injecting someone with roids raises CHRONIC levels of testosterone, and this accounts for increased muscle growth, whereas the neuroendocrine response is an ACUTE (30 minute) effect. This is a significant difference which makes the two cases unanalogous.
