Every Man Over 40 Should Probably Know His Testosterone Level

Testosterone levels in American men have been declining for decades — measurably, generationally, in ways that are not fully explained by aging alone. Men in their thirties today have meaningfully lower testosterone on average than men in their thirties did in the 1980s. One in five men under 40 meets the clinical definition of testosterone deficiency. Four in ten men over 45 have low testosterone. And the vast majority of them have never been told.Not because the symptoms aren't there. They are. But because the symptoms of low testosterone — fatigue, low motivation, mood changes, body composition shifts, loss of drive — look exactly like what society tells men getting older is supposed to feel like. So they accept it. They blame work stress, poor sleep, getting older. They never ask the question that might actually have an answer.This is a personal episode. Dr. Chris Lee talks about his own relationship with hormone health — what he has checked, how he thinks about it at his age and stage, and why he believes this conversation is one of the highest-ROI health discussions any man can have. He covers what low T actually looks like beyond the libido clichés, what labs to actually order and what the numbers mean, what TRT involves and who it's right for, who it isn't right for, and where peptides and adjunct therapies fit into the fuller picture of male optimization.
