And the most damaging thing — the thing that kept him from finding the answer for three years — was that he had concluded this was just what 56 looks like.
What I need to tell you before I explain the mechanism is this.
The men in my practice who were living what Frank was living had not been passive about it. They had tried things. Multiple things. Repeatedly.
They trained harder. Changed the diet. Went to the doctor. Were sent home with normal for your age. Tried a supplement. Tried another supplement. Found the third one did nothing and concluded the category was broken.
That conclusion was rational. If I had tried three products over four years and none of them had worked, I would reach the same conclusion.
It was also wrong. And the reason it was wrong is specific, mechanical, and has nothing to do with the supplements being ineffective in principle. It has to do with the dose those supplements contained versus the dose the clinical research actually used.
But I will come back to the dose in a moment. First I need to explain what was actually happening in Frank’s body, because without understanding the mechanism, the dose revelation means nothing.
Testosterone and cortisol are biological antagonists.
Most people know that testosterone declines after 40 — one to two percent per year, gradually, without announcement. By 55, most men are 25 to 35 percent below their peak. Still within the normal range on a standard blood test. Which is why the standard blood test kept sending Frank home with normal for your age.
What the standard blood test was not designed to measure is what happens to cortisol when testosterone drops below its regulatory threshold.
Testosterone’s most important and least discussed clinical function is keeping cortisol — the body’s primary stress hormone — within functional limits. When testosterone is adequate, this regulatory balance holds. The afternoon cortisol spike stays manageable. The body responds to training. The neurochemicals behind mood, motivation, and drive stay in equilibrium. The automatic desire arrives without requiring a reason.
When testosterone drops below the regulatory threshold, cortisol stops being regulated. It runs completely unchecked. Every day. Without a counter.
Unregulated cortisol spikes every afternoon and depletes every reserve before the day is over. That is the wall. That is the sofa. That is the nothing left.
Unregulated cortisol drives visceral abdominal fat storage at the hormonal level, regardless of training effort and regardless of caloric intake. The effort goes in. Cortisol intercepts the output before it can compound. That is why the belly does not respond to the gym.
Unregulated cortisol directly suppresses the neurochemicals behind motivation, emotional stability, and what my patients describe as just feeling like themselves. That is the general bummer. The restless and lazy. The flatness with no external cause.
Unregulated cortisol suppresses the neurological pathway that generates automatic desire. The reaching. The wanting. The part that used to arrive on a Tuesday for no reason. That is where the man went who used to reach first.
The afternoon wall. The belly. The fog. The mood. The drive going quiet. The side character.
Not six separate problems.
