As someone who’s crossed the 30-year milestone, I’ve noticed subtle changes in my body and mood that I never paid attention to in my younger days. It started with feeling less energized, occasional brain fog, and let’s be honest—wondering if I was losing a bit of the edge I once took for granted. At first, I brushed it off as part of life, but then I stumbled upon something that surprised me: testosterone.

Did you know that testosterone, the hormone most associated with vitality and masculinity, peaks during adolescence and early adulthood? After 30, it begins to decline by about 1% each year. That might not sound like much, but over time, it adds up. Low testosterone—often called “Low T”—doesn’t just affect energy and muscle tone. It can also increase the risk of issues like erectile dysfunction and even depression.
