It might not just be stress or aging. If you’re over 40, there’s a good chance you’re experiencing some of the signs of low testosterone—a condition affecting millions of men in the U.S., often without them realizing it.

Let’s break down the most common symptoms and how to know when it’s time to take action.


Why Testosterone Matters After 40

Testosterone plays a vital role in everything from mood to muscle mass. But after age 30, levels naturally decline—about 1% per year.

For some men, this drop causes no issues. For others, it creates a perfect storm of low energy, mental fog, and emotional flatness.

“I thought I was just getting old… turns out my T levels were lower than normal for a 70-year-old.” — Reddit user @over40fatigue
