There is a lot of misinformation out there in the bodybuilding world. I like to call it bro-logic. It's the dumb one-liners you hear brobros telling each other in the gym; toolbags passing misinformation back and forth like a venereal disease (believe me, it's that bad). Things like "repping out is 12 reps, dude," or "yeah bro, let's do another set--you're hella strong!" after a set of all forced reps. Sigh. This is why I listen to EDM so loud at the gym--I have to in order to drown out the retardation.
Oftentimes, the most dangerous, pervasive, and completely-off-base bro-logic centers around human endocrinology--you know, hormones and stuff. Because of the ultra-obvious elephant in the gym, many do not bother educating themselves enough about managing and manipulating the body's natural hormonal responses to training, diet, and other external and internal stimuli.
