because your body tries to maintain homeostasis... imagine if u got bigger just by eating more protein lol, just imagien what the fuck society would look like
test is not that important, there's a lot of misconceptions in society... everyone wants to be a high testosterone male, or estrogen is supposed to be a femine hormone... it's all kind of like marketing, it's all bullshit, sure if u have no test or estrogen in ur body u may not get a boner, but walking home ater a work out i have to put effort toward maintain a falccid penis becaue i want to fuck anyone and everyone. but test is low after a work out, so test is just not that important
