It'd be a nice theory but we actually know that as men get their testosterone levels lower they get to be at higher and higher risk of certain diseases. For example, testosterone is often cited as carrying risk of CVD and for many years we were confused why men with below low cutoff testosterone are at even higher risk of CVD than men just above high cutoff. As it turns out, estrogen, another sex hormone, pretty important for CV health is made through aromatisation from testosterone in the walls of blood vessels. Thus, surprisingly being low on testosterone actually increases risk of CVD through estrogen insufficiency. Yes, human endocrine system is complicated like that, and no, testosterone is not a fashion or something we can improve because we're smarter. We're studying AAS for about 70 years now and we still know pretty little. Testosterone and estrogen are "kinda" understood as they're mainly endocrine hormones. As for those secreted in para- and autocrine fashion (e.g. DHT) we still know not enough.
