The Complete Guide to Testosterone Replacement Therapy for Men Over 40

If you're a man over 40 and you've noticed declining energy, unexplained weight gain, reduced motivation, or changes in your sex drive, you're not imagining things. These are real symptoms — and they may be related to declining testosterone levels.

Testosterone naturally decreases by about 1-2% per year after age 30. By 45, many men are experiencing the effects. The good news: testosterone replacement therapy (TRT) is safe, effective, and can genuinely transform how you feel.

Here's everything you need to know.

Signs of Low Testosterone

Low testosterone (often called "Low T") doesn't just affect one area of your life. It's systemic:

Physical symptoms:

• Persistent fatigue despite adequate sleep
• Increased body fat, especially around the midsection
• Loss of muscle mass and strength
• Decreased bone density

Mental/emotional symptoms:

• Brain fog and poor concentration
• Irritability or mood swings
• Reduced motivation and drive
• Depression or anxiety (sometimes misdiagnosed)

Sexual health symptoms:

• Decreased libido
• Erectile dysfunction
• Reduced sexual satisfaction

If you're experiencing three or more of these symptoms, it's worth getting your levels checked.

Testing: More Than Just One Number

A proper testosterone evaluation includes more than just "total testosterone." At Precision Health, our hormone panel includes:

• Total Testosterone — the overall amount in your blood
• Free Testosterone — the bioavailable amount your body can actually use
• SHBG (Sex Hormone Binding Globulin) — affects how much testosterone is available
• Estradiol — estrogen levels (yes, men have estrogen too, and it matters)
• DHEA — a precursor hormone
• PSA — prostate safety screening
• CBC and Metabolic Panel — baseline health markers

We look at the complete picture, not just one number. Many men are told their testosterone is "normal" because it falls within the lab reference range (250-1,000 ng/dL), even though they feel terrible at 300. There's a difference between "normal" and "optimal."

Treatment Options

If TRT is appropriate for you, several delivery methods are available:

Injectable Testosterone (Most Common)

• Weekly self-injections (we teach you how)
• Most cost-effective option
• Consistent, reliable delivery
• Our patients' most popular choice

Topical Creams/Gels

• Applied daily to the skin
• No needles required
• Good option for needle-averse patients
• Requires avoiding skin contact with others after application

Testosterone Pellets

• Tiny pellets inserted under the skin every 3-6 months
• "Set it and forget it" convenience
• Consistent levels without daily or weekly dosing

Dr. Brown will recommend the best option based on your lifestyle, preferences, and how your body responds.

What to Expect on TRT

First 2-4 Weeks

• Improved energy and mood (often the first things patients notice)
• Better sleep quality
• Reduced brain fog

4-8 Weeks

6-12 Months

• Optimal results achieved
• Body composition significantly improved
• Lab markers optimized

Safety and Monitoring

TRT is safe when properly prescribed and monitored. At Precision Health, we check:

• Hematocrit/Hemoglobin — TRT can increase red blood cell production
• PSA — prostate monitoring
• Lipid panel — cardiovascular health
• Liver function — metabolic safety
• Estradiol — to manage estrogen conversion

We monitor these markers every 6-12 weeks initially, then every 3-6 months once stable.

1. In-person evaluation — physical exam, not just a questionnaire
