Low testosterone doesn't announce itself with a single symptom. It creeps in slowly—a little less energy here, slightly lower libido there, gradual changes you might write off as "just getting older." But these signs often point to something fixable.
The Numbers
Signs Your T Might Be Low
Not just tired after a bad night—persistently low energy regardless of sleep. The kind of fatigue that coffee can't fix. You feel drained by mid-afternoon, every day.
Sex drive that's dropped noticeably. Less interest, less spontaneous arousal, maybe erection issues. This is often the first sign men notice—and the most frustrating.
You're training the same but getting softer. Muscle seems harder to build and easier to lose. Body fat accumulates, especially around the midsection.
Difficulty concentrating, memory issues, irritability, or low mood. Testosterone affects your brain directly—low T can make you feel mentally sluggish and emotionally flat.
That fire you used to have—for work, for the gym, for life—feels diminished. You're going through the motions instead of attacking your goals.
What Causes Low T?
| Factor | Impact |
|---|---|
| Age | Natural 1% annual decline after 30 |
| Poor Sleep | Most T is produced during deep sleep |
| Stress | Cortisol directly suppresses testosterone |
| Body Fat | Fat tissue converts T to estrogen |
| Diet | Nutrient deficiencies impair T production |
| Sedentary Lifestyle | Exercise is essential for healthy T levels |
What You Can Do
Get tested. A simple blood test shows your total and free testosterone. Don't accept "normal"—ask for the actual numbers. Optimal is different from just scraping by in the reference range.
Fix the foundations:
- Sleep 7-9 hours (non-negotiable)
- Lift weights regularly
- Manage stress and cortisol
- Maintain healthy body fat
- Eat adequate protein and healthy fats
Support naturally. Once your foundations are solid, natural testosterone optimisers can push your levels higher without the commitment or risks of TRT.
