Testosterone plays a central role in men’s health, influencing muscle mass, energy, mood, libido, and overall vitality. Yet many men are unsure whether their numbers are “good” or a cause for concern. This guide breaks down healthy testosterone levels by age, explains what the numbers really mean, and answers the most common questions men ask about testosterone.
Key Insights
- Healthy testosterone levels by age generally fall between 300–1,000 ng/dL, with natural variation based on age and individual health.
- Testosterone levels peak in early adulthood and decline by about 1% per year after age 30.
- Most men feel optimal with levels between 400–700 ng/dL.
- A 500 testosterone level is considered good for most men and supports normal energy, mood, and sexual function.
- 700 ng/dL is high-normal, not excessively high, especially in younger or active men.
- Levels below 300 ng/dL are often considered low, particularly when symptoms are present.
- Common symptoms of low testosterone include fatigue, low libido, muscle loss, weight gain, mood changes, and brain fog.
- Testosterone is typically measured in ng/dL, and results should always be evaluated alongside symptoms.
- Natural ways to boost testosterone levels include strength training, quality sleep, stress management, healthy nutrition, and maintaining a healthy body weight.
What Is Testosterone, and Why Does It Matter?
Testosterone is the primary male sex hormone, produced mainly in the testes.
It supports:
- Muscle growth and strength
- Bone density
- Sex drive and fertility
- Red blood cell production
- Mental focus and confidence
Levels naturally fluctuate throughout the day, usually peaking in the morning. Over time, age, lifestyle, stress, sleep, and health conditions all influence testosterone production.
Testosterone Units Explained
Before comparing numbers, it helps to understand how testosterone is measured.
Most labs report testosterone as nanograms per deciliter (ng/dL). Some countries also use nanomoles per liter (nmol/L).
- 300 ng/dL ≈ 10.4 nmol/L
- 500 ng/dL ≈ 17.3 nmol/L
- 700 ng/dL ≈ 24.3 nmol/L
When reading lab results, always confirm the units and the lab’s reference range.
Normal Testosterone Levels by Age
Below is a commonly accepted breakdown of testosterone levels by age for adult men. Ranges may vary slightly by laboratory.
| Age Group | Normal Testosterone Level |
| Male Infants (0–6 months) | 75 – 400 ng/dL |
| Children (around age 10) | 7 – 130 ng/dL |
| Early Teens (12–13 years) | 7 – 800 ng/dL |
| Mid Teens (15–16 years) | 100 – 1,200 ng/dL |
| Late Teens (17–18 years) | 300 – 1,200 ng/dL |
| Adults (19+ years) | 300 – 1,000 ng/dL |
| Adults (30+ years) | 300–900 ng/dL |
| Adults (40+ years) | 300–850 ng/dL |
| Adults (50+ years) | 250–800 ng/dL |
| Adults (60+ years) | 200–700 ng/dL |
These average testosterone levels in men reflect the population averages, not necessarily what is optimal for you.
What Is a Healthy Testosterone Level at 30?
One of the most common question is “what is a healthy testosterone level at 30?”. For most men in their 30s, levels between 400 and 700 ng/dL are considered healthy and supportive of good energy, strength, and libido. While levels above 300 ng/dL are often labeled “normal,” many men feel their best closer to the mid-to-upper range.
Is a 500 Testosterone Level Good?
Yes, for most men, a 500 testosterone level is good. It sits comfortably in the healthy range and is associated with normal sexual function, muscle maintenance, and mood stability. If you feel well and have no symptoms, a level around 500 ng/dL is generally not a concern.
What is testosterone 400?
Testosterone 400 refers to a total testosterone level of 400 ng/dL. While technically within the normal range, some men may begin to notice mild symptoms at this level, depending on genetics, lifestyle, and sensitivity to hormonal changes. Others feel perfectly fine. Numbers should always be evaluated alongside symptoms, not in isolation.
Testosterone Decrease After 30
Yes. Testosterone typically declines by about 1% per year after age 30. This gradual drop explains why many men notice changes in energy, recovery, or body composition as they age. However, lifestyle choices can significantly slow this decline.
Many men explore natural ways to boost testosterone levels, such as strength training, better sleep, stress reduction, and balanced nutrition, before considering medical options.

Symptoms of Low Testosterone
Low testosterone (often defined as consistently below 300 ng/dL) may cause:
- Low sex drive
- Erectile dysfunction
- Fatigue or low energy
- Loss of muscle mass
- Increased body fat
- Mood changes or depression
- Difficulty concentrating
If symptoms are present, further evaluation is recommended even if levels are borderline.
How Low Is Too Low, and When Should You See a Doctor?
In most clinical settings, testosterone levels below 300 ng/dL are considered low, especially when confirmed by repeat morning blood tests. However, some men may experience symptoms at slightly higher levels, while others may feel fine below this threshold.
Men with repeated low readings, worsening symptoms, or significant quality-of-life changes should not ignore these signs. A doctor can evaluate underlying causes, rule out other conditions, and discuss appropriate next steps.
Untreated low testosterone may affect bone density, metabolic health, mood, and long-term vitality. Early evaluation allows for a broader range of options, including lifestyle optimization, nutritional strategies, or medical guidance when appropriate.
Ways to Boost Testosterone Levels Naturally
Many men can support healthy testosterone levels through lifestyle changes before considering medical treatment. While results vary by individual, the strategies below are widely supported by research and clinical guidance.
1. Prioritize Strength Training
Resistance training, such as weightlifting and bodyweight exercises, is one of the most effective natural ways to boost testosterone levels. Compound movements like squats, deadlifts, bench presses, and rows stimulate larger muscle groups and promote hormone production. Aim for consistent training rather than excessive volume, as overtraining can have the opposite effect.
2. Improve Sleep Quality
Testosterone is primarily produced during sleep. Poor or insufficient sleep can significantly lower levels, even in young, healthy men. Most men need 7–9 hours of quality sleep per night to support optimal hormone balance. Chronic sleep deprivation is one of the fastest ways testosterone declines.
3. Manage Stress Levels
High stress increases cortisol, a hormone that directly suppresses testosterone production. Long-term stress from work, lack of recovery, or mental health strain can contribute to lower levels. Techniques such as meditation, deep breathing, walking, and adequate downtime can help restore hormonal balance.
4. Eat a Testosterone-Supportive Diet
Extreme dieting and very low-fat diets can negatively impact testosterone production. A balanced, nutrient-dense diet supports healthy hormone levels by providing the building blocks the body needs to produce testosterone efficiently.
This includes consuming healthy fats from sources such as olive oil, avocados, nuts, and eggs, along with adequate protein to support muscle maintenance and recovery.
5. Maintain a Healthy Body Weight
Excess body fat, especially around the abdomen, can increase the conversion of testosterone into estrogen. Reducing excess fat through sustainable diet and exercise often leads to noticeable improvements in testosterone levels.
6. Limit Alcohol and Avoid Substance Abuse
Heavy alcohol consumption and drug use are linked to lower testosterone production. Moderation plays a key role in long-term hormonal health.
Many men focus on these natural ways to boost testosterone levels as a first step, especially when levels are borderline rather than clinically low.
