Low testosterone (also called “Low T”) is one of the most common — and most misunderstood — health issues men face as they age. But here’s the truth most guys don’t hear: low testosterone doesn’t just affect your sex drive. It impacts your energy, mood, motivation, muscle, sleep, confidence, and even how clearly you think.

If you’ve been feeling “off” lately, this guide will help you understand what's going on — without confusing medical language. And if any of this sounds familiar, AgeMD’s hormone specialists can help test, diagnose, and treat low testosterone safely.

What Testosterone Really Does

Testosterone controls:

  • Energy and stamina

  • Muscle strength

  • Libido and sexual function

  • Mood

  • Mental clarity

  • Metabolism and fat storage

When testosterone drops, it affects everything.

Common Signs of Low Testosterone

You don’t need a blood test to suspect something is wrong:

  • Low or inconsistent sex drive

  • Weak erections or reduced morning erections

  • Belly fat increase

  • Muscle loss

  • Mood changes

  • Low confidence

  • Brain fog

  • Sleep issues

  • Slow workout recovery

Why Testosterone Drops

Common causes include:

  • Aging

  • Stress

  • Poor sleep

  • Blood sugar problems

  • Weight gain

  • Medications

  • Thyroid issues

How Low Testosterone Is Diagnosed

AgeMD checks:

  • Total testosterone

  • Free testosterone

  • Estradiol

  • SHBG

  • Thyroid markers

  • Cortisol & DHEA

  • Metabolic labs

This ensures the most accurate diagnosis.

What Happens If You Ignore It?

Treatment Options

  1. TRT (Testosterone Replacement Therapy).
    Restores testosterone to optimal levels.
    Benefits: - Higher libido - Improved erections - More energy - Better strength - Less belly fat - Sharper focus

  2. Enclomiphene (Restart Therapy).
    Boosts natural testosterone — ideal for men who want to maintain fertility.

  3. Thyroid Optimization
    Thyroid and testosterone are closely connected.

  4. Peptides
    Support recovery, sleep, and hormone signaling.

Is TRT Safe?

When supervised properly, TRT is extremely safe. AgeMD follows strict monitoring:

  • Regular blood tests

  • Estrogen balance checks

  • Hematocrit monitoring

  • Personalized dose adjustments

How Fast Will You Feel Results?

  • 2–4 weeks: Better mood & energy

  • 6–8 weeks: Higher libido & improved erections
