Are you wondering, What is a good TRT dosage per week? You’re not alone! Testosterone replacement therapy (TRT) has become a popular treatment for men with low testosterone levels. But, determining the right dosage is crucial for getting the best results while minimizing side effects.

In this article, we’ll break down everything you need to know about TRT dosages: what’s typical, how to figure out the right dose for your needs, and what factors affect it. Whether you’re just starting TRT or tweaking your treatment plan, you’ll find helpful insights here.
What is Testosterone Replacement Therapy (TRT)?
Testosterone replacement therapy is used to treat men with low testosterone, often referred to as low T. Testosterone is a hormone that plays a vital role in mood, energy, muscle mass, and libido. When testosterone levels drop too low, it can cause various symptoms like fatigue, decreased sex drive, and difficulty building muscle.
TRT helps restore testosterone levels to a healthy range and improve these symptoms. It’s available in different forms, such as:
- Injectable testosterone (most commonly used)
- Topical testosterone gels
- Testosterone patches
- Pellet implants
For this article, we’ll focus mainly on injectable testosterone, which is a go-to choice for many men.
What is a Good TRT Dosage Per Week?
When it comes to what is a good TRT dosage per week, there’s no one-size-fits-all answer. Dosage varies based on individual needs, age, and overall health. However, there are general guidelines that can help you understand what to expect.
Typical TRT Dosage for Beginners
For most men, a good starting dosage is typically 100 to 200 mg per week. This is the most common range prescribed by doctors for men diagnosed with low testosterone. Your dosage might be adjusted over time based on your response to treatment and blood test results.
- 100 to 200 mg per week is a common starting point.
- Some men may need a higher dose, up to 300 mg per week, if they don’t respond well to lower dosages.
- Your healthcare provider will recommend whether to inject once a week or split the dosage into two injections (e.g., Monday and Thursday).
Factors That Affect Your TRT Dosage
Here are a few things that influence how much testosterone you need:
- Your Testosterone Levels: The first step in determining your dosage is a blood test to check your current testosterone levels. If you’re in the low-to-normal range, your doctor will adjust your dose accordingly.
- Your Age: Younger individuals may need slightly higher doses to achieve optimal testosterone levels, while older men might need less.
- Body Composition: People with higher body fat may need a higher dosage, as fat cells absorb more testosterone.
- Your Symptoms: If your symptoms (like low energy or poor libido) are more severe, you may start with a higher dosage.
- Health Conditions: Certain health conditions, such as diabetes or heart disease, may require adjustments to your dosage to ensure safety.
Injection Frequency: Should You Inject Once a Week or More Often?
Many people are curious about how often they should inject testosterone. While some men stick to a once-a-week schedule, others may find that more frequent injections work better for keeping testosterone levels steady throughout the week.
Injection Schedules You Might Encounter:
- Once a week: Most people start with this frequency. It’s simple, convenient, and effective for many.
- Twice a week: Injecting more frequently can help avoid fluctuations in your testosterone levels, leading to more consistent results.
- Every 3 to 4 days: If you experience large swings in your testosterone levels, your doctor might suggest injecting more frequently.
The key here is to maintain stable testosterone levels, and this varies from person to person. Your healthcare provider will recommend what’s best for you.
How to Administer TRT Injections Safely
Administering your testosterone shots correctly is just as important as getting the dosage right. Here are a few tips for ensuring your injections go smoothly:
- Choose the Right Injection Site: Common sites for injections include the glutes (buttocks) or thigh muscles.
- Rotate Injection Sites: To prevent irritation or scarring, make sure you switch up where you inject.
- Use the Correct Needle Size: Your doctor will recommend the appropriate needle and syringe for your injections.
- Stick to the Schedule: Injecting on time and as prescribed is key to maintaining consistent testosterone levels.
Monitoring Your TRT and Adjusting Dosages
Once you begin TRT, regular check-ups are essential to ensure you’re on the right track. Monitoring involves not just testosterone levels, but also other factors like red blood cell count and general health.
Typically, your doctor will order blood tests every 3 to 6 months to see if your levels are in the optimal range and to check for any potential side effects. Common tests include:
- Total testosterone levels: The target range is generally 300–1,000 ng/dL.
- Red blood cell count: High testosterone can increase red blood cell production.
- Hematocrit and hemoglobin: These will be checked to ensure your blood isn’t becoming too thick, which could lead to complications.
If your levels are off or you’re experiencing side effects, your doctor will adjust your dosage accordingly.
The Benefits of TRT
When used correctly, TRT has a variety of benefits. Some of the most noticeable include:
- More energy and less fatigue
- Improved mood and cognitive function
- Enhanced libido and sexual performance
- Increased muscle mass and strength
- Better bone density
- Improved sleep quality
These benefits can drastically improve your quality of life, especially if you’ve been suffering from low testosterone symptoms for a long time.
Possible Side Effects of TRT
Like any medical treatment, TRT can come with side effects. Some of the most common side effects include:
- Acne or oily skin
- Sleep apnea
- Increased red blood cell count
- Fluid retention
- Testicular shrinkage
If you experience any of these side effects, it’s important to talk to your doctor. They can adjust your dosage or explore other treatment options.
Conclusion: Finding Your Ideal TRT Dosage
In conclusion, what is a good TRT dosage per week? The answer is not the same for everyone. While most people start with 100 to 200 mg per week, it’s important to tailor your dosage to your individual needs. Your doctor will work with you to monitor your testosterone levels and symptoms to find the right balance.
Remember, consistency is key. Stick to your prescribed schedule and keep an eye on any side effects. With the right dosage and regular monitoring, TRT can significantly improve your energy, mood, and overall well-being.
