Why Do I Feel So Tired After a Testosterone Shot?


If you’ve recently received a testosterone shot, it’s not uncommon to feel tired or experience fatigue afterward. While testosterone therapy is generally beneficial for many individuals, it can sometimes lead to temporary side effects, including fatigue. In this article, we will explore the reasons why some people may feel tired after a testosterone shot and provide useful information to help you understand and manage this potential side effect.

Understanding Testosterone Therapy:

Testosterone therapy, commonly prescribed to address low testosterone levels in men, can offer various benefits, such as increased energy, improved mood, enhanced sexual function, and muscle growth. However, as with any medical treatment, it can also have side effects. Feeling tired or experiencing fatigue after a testosterone shot is one such potential side effect that some individuals may encounter. It’s essential to understand why this happens to effectively manage any discomfort and seek appropriate medical advice if needed.

Possible Reasons for Feeling Tired:

1. Hormonal Imbalance:

Testosterone shots can cause hormonal fluctuations in the body, which can sometimes result in feelings of fatigue. When you receive a testosterone shot, it stimulates the production of testosterone in your body. This sudden increase in testosterone levels can disrupt the balance of other hormones, such as cortisol, leading to fatigue.

2. Metabolic Changes:

Testosterone therapy can affect your body’s metabolic rate. Some individuals may experience an increase in metabolism, which can lead to a higher energy expenditure. This increased energy usage may result in feelings of tiredness, especially if your body is not accustomed to this change.

3. Sleep Disruption:

Testosterone shots can also affect your sleep patterns. Some individuals may experience difficulty falling asleep or staying asleep after receiving a testosterone shot. This can lead to inadequate or disrupted sleep, resulting in daytime fatigue.

4. Psychological Factors:

Feeling tired after a testosterone shot may also be influenced by psychological factors. The anticipation of side effects or anxiety related to the treatment itself can contribute to feelings of fatigue. Additionally, if you’re experiencing mood changes, such as irritability or depression, they can also impact your energy levels.

Managing Fatigue After a Testosterone Shot:

While feeling tired after a testosterone shot can be bothersome, there are several strategies you can try to manage this side effect effectively. It’s crucial to consult with your healthcare provider before implementing any changes, as they can provide personalized advice based on your specific circumstances.

1. Adjusting Dosage or Injection Frequency:

If you consistently experience fatigue after receiving a testosterone shot, your healthcare provider may consider adjusting the dosage or injection frequency. Modifying these factors can help minimize the side effects while still maintaining the benefits of testosterone therapy.

2. Ensuring Adequate Sleep:

To combat sleep disturbances, it’s important to prioritize quality sleep. Establish a consistent sleep schedule, create a relaxing bedtime routine, and make your sleep environment conducive to rest. Avoiding stimulants like caffeine close to bedtime and minimizing exposure to electronic devices before sleep can also promote better sleep.

3. Managing Stress Levels:

Stress can exacerbate fatigue, so it’s important to find healthy ways to manage stress levels. Engaging in relaxation techniques, such as deep breathing exercises, meditation, or yoga, can help reduce stress and promote overall well-being. Additionally, engaging in regular physical activity can also have a positive impact on stress levels and energy levels.

4. Maintaining a Balanced Lifestyle:

Adopting a healthy lifestyle can aid in managing fatigue after a testosterone shot. Focus on consuming a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Stay hydrated by drinking plenty of water throughout the day. Regular exercise, within your healthcare provider’s recommendations, can also contribute to increased energy levels and overall well-being.


Now, let’s address some frequently asked questions regarding feeling tired after a testosterone shot:

1. How long does fatigue typically last after a testosterone shot?

Fatigue can vary from person to person. While some individuals may experience fatigue for a few days following a testosterone shot, others may find it subsides within a few hours. If your fatigue persists or becomes severe, it’s important to consult with your healthcare provider for further evaluation.

2. Can certain medications or medical conditions contribute to increased fatigue after a testosterone shot?

Yes, certain medications or medical conditions can influence fatigue levels. It’s essential to inform your healthcare provider about all the medications you are taking, as well as any existing medical conditions. They can assess the potential interactions and provide appropriate guidance.

3. Are there any warning signs that indicate I should seek medical advice for fatigue after a testosterone shot?

While feeling tired after a testosterone shot is generally considered a common side effect, there are instances where medical advice should be sought. If your fatigue is severe, persistent, or accompanied by other concerning symptoms, such as shortness of breath, chest pain, or dizziness, it’s important to consult with your healthcare provider promptly.

4. Can lifestyle factors impact fatigue levels after a testosterone shot?

Yes, lifestyle factors play a crucial role in managing fatigue. Prioritizing good sleep habits, managing stress levels, and maintaining a balanced lifestyle can help minimize fatigue after a testosterone shot. Additionally, avoiding excessive alcohol consumption and quitting smoking, if applicable, can also contribute to overall well-being and energy levels.


Feeling tired after a testosterone shot is a potential side effect that some individuals may experience. Understanding the reasons behind this fatigue can help manage it effectively. By working closely with your healthcare provider, you can adjust your treatment plan, address any underlying factors, and adopt strategies to mitigate fatigue. Remember, if you have any concerns or the fatigue persists, always consult with your healthcare provider for personalized advice and guidance.
