Introducing Testosterone and "Low T" from Drug Story. Follow the show: Drug Story It used to be that getting older meant slowing down. A little less pep, a little less zip, a little less zest. So it goes. For men, this was partly about testosterone. After 40 or so, our bodies produce less and less testosterone, the hormone that helps give men energy and vigor and sex drive. Lower testosterone was just part of growing older. But that was then! Nowadays, “Low T” is a bonafide medical condition - easily treated with a shot at your local neighborhood men’s health clinic. Today, what used to be a secret sauce of bodybuilders or cheating athletes is now downright normal. Millions of men worldwide take testosterone therapy - and not just those over 40. Check out Reddit or TikTok...It is a WHOLE THING. In this episode of Drug Story, we look at how TRT went mainstream, and how part of ordinary aging somehow became a disease.
