In defense of the people getting it: that's kind of the tricky part.
My understanding of medical science is that we have a big wide range of what "normal" testosterone levels are in males, and it's expected to drop to some extent as you age, but the range is so big as to be almost meaningless.
I'm not sure what the long-term answer is, but we could benefit a lot from long-term studies on T levels throughout the male lifetime to get a better idea of what the optimal level is for at least the "average" male.
This feels like one of the areas of study that is politically problematic, and therefore avoided.
