Testosterone injections can lead to a variety of physical and emotional effects. Here are some quick answers to common questions about how you may feel after receiving a testosterone shot:
Immediately After the Injection
You may experience:
- Slight pain or burning at the injection site
- Bleeding or bruising at the injection site
- Dizziness or lightheadedness from the injection process
These sensations should go away within a few minutes. Applying pressure and cleaning the injection site can help minimize pain and bleeding.
Later the Same Day
Later in the day after your testosterone injection, you may notice:
- Increased energy and alertness
- A boost in mood and motivation
- More mental clarity and ability to focus
- Enhanced sex drive and arousal
- A greater sense of well-being and confidence
These effects occur as the testosterone circulates through your system and starts to take effect. The surge of testosterone can make you feel more energetic, driven, and sexually charged.
The Next Few Days
Over the next few days following your injection, you may continue to experience:
- Higher energy levels and stamina
- Increase in strength for workouts and exercise
- Better mood and sense of motivation
- More mental clarity and ability to concentrate
- Continued increase in sex drive
The benefits of the testosterone shot tend to peak in the days after receiving it. You’ll likely feel capable, energized, and driven to accomplish your goals.
Downsides and Side Effects
Potential downsides and side effects include:
- Mood swings – emotions may feel more volatile
- Headaches or migraines – from hormone fluctuations
- Acne outbreaks – testosterone stimulates oil glands
- Sleep disturbances – you may have trouble falling or staying asleep
- Changes in testicle size – testosterone can cause shrinkage
If you experience negative side effects, discuss them with your doctor. Adjusting your dosage or frequency may help manage side effects.
When Benefits Wear Off
The effects of a testosterone injection typically start to wane after around 7-10 days. As your hormone levels decline, you may feel:
- Decrease in energy, stamina, and motivation
- Reduced strength and endurance for exercise
- Drop in sex drive and difficulty getting or maintaining erections
- Loss of mental sharpness and ability to focus
- Lower mood, and sense of well-being and confidence
This dip is normal as your testosterone returns to baseline pre-injection levels. Timing your next injection before the low point can help maintain optimal hormone levels.
Long-Term Changes
With consistent testosterone therapy over months or years, you may experience these ongoing effects:
- Increased muscle mass and strength
- Decreased body fat and thinner waistline
- Denser, stronger bones
- Resolution of erectile dysfunction
- More energy, stamina, and ability to build muscle with exercise
- Improved mood, mental sharpness, and motivation
Testosterone injections can help restore normal hormone levels in deficient men, providing a variety of physical and emotional benefits.
Conclusion
Testosterone injections lead to both immediate and long-lasting effects. In the short-term, you may feel more energetic, driven, and sexually charged. Some side effects like mood swings may occur. Long-term benefits include increased muscle mass, improved mood and motivation, and restored sexual function. Learning how you respond to testosterone therapy can help you maximize the benefits while managing potential side effects.

Frequently Asked Questions
How soon after a testosterone injection will I feel the effects?
You may start to feel increased energy, sex drive, and mood enhancement within a few hours of receiving the injection. The effects tend to peak in the first 1-2 days and remain elevated for around 7-10 days afterwards before tapering off.
What are the most common side effects of testosterone injections?
Common side effects can include mood swings, headaches, acne, sleep disruptions, enlargement of the prostate, and shrinking testicles. However, side effects are usually mild and can be managed by adjusting dosage and injection frequency.
How often do you need testosterone injections for best results?
Most men receive testosterone injections every 7-14 days. Frequency depends on the formulation and your individual hormone metabolism. Work with your doctor to determine the optimal injection schedule for consistent symptom relief and to avoid peaks and troughs.
How long does it take to notice the benefits of testosterone therapy?
Some positive effects may be apparent within a few hours or days after starting therapy. But it can take 2-3 months of regular injections for testosterone levels to stabilize and the full effects on energy, sexual function, muscle growth, and mood to become apparent.
Can testosterone injections permanently increase testosterone?
No, testosterone injections provide only temporary increases in testosterone levels. Levels will return to baseline within 1-2 weeks after each injection, hence the need for ongoing regular injections to maintain the benefits.
Do testosterone injections increase the size of the penis?
Testosterone injections can sometimes increase the length and girth of the penis by causing growth of penile tissues and increased blood flow. However, significant size changes are uncommon. If erectile dysfunction is present, testosterone therapy may improve erection quality and “usable” penis size.
How much does a course of testosterone injections usually cost?
The cost for testosterone injections varies depending on the specific medication, dosage, clinic fees, and health insurance coverage. Expect to pay $200-$500 for a 10mL vial, with insurance bringing the out-of-pocket cost down to $20-$75 per month in many cases.
Are there alternatives if you don’t want testosterone injections?
Yes, alternatives for boosting low testosterone include gels, patches, pellets, nasal sprays, and oral capsules. Each approach has pros and cons to discuss with your doctor. Injections tend to provide the most consistent absorption and testosterone levels.
Here is a comparison table of the different testosterone replacement options:
| Treatment | Method of Administration | Frequency | Pros | Cons |
|---|---|---|---|---|
| Injections | Intramuscular injection | Every 2-7 days | Provides consistent testosterone levels, convenient | Injections required, peaks and valleys in levels |
| Gels | Applied to arms/shoulders | Daily | Easy to administer, mimics natural secretion | Potential skin irritation, transfer to others |
| Patches | Worn on arm, back, lower abdomen | Daily | Easily self-administered, mimics natural secretion | Can irritate skin, fall off |
| Pellets | Inserted under the skin | Every 3-6 months | Consistent long-term release, only needed a few times per year | Requires doctor’s visit for insertions |
| Nasal Sprays | Nasal inhaler | 2-3 times per day | Convenient dosing, portable | Can irritate nasal passages, variable absorption |
| Oral Capsules | Taken by mouth | 2-3 times per day | Easily self-administered | Processed through liver, less testosterone reaches circulation |
Discuss your personal preferences and needs with your doctor to determine which testosterone replacement method is right for you.
Lifestyle Changes to Support Treatment
You can enhance the benefits of testosterone therapy by adopting some supportive lifestyle habits:
- Strength train – Lifting weights triggers your body to utilize testosterone to build muscle.
- Eat nutritious foods – A diet rich in protein, healthy fats, and micronutrients provides fuel for testosterone.
- Reduce stress – Keeping cortisol under control maximizes testosterone effects.
- Get plenty of sleep – Aim for 7-9 hours per night for optimal testosterone production.
- Achieve a healthy weight – Excess body fat causes lower testosterone levels.
Making fitness, nutrition, stress management, and rest priorities enhances your capacity to benefit from testosterone replacement therapy.
The Takeaway
Testosterone injections can produce noticeable effects on energy, mood, motivation, sexual function, and muscle growth. While some men experience side effects like acne or sleep disruptions, most find the benefits of testosterone therapy outweigh the potential downsides.
Learning how your body responds to injections allows you to time them properly for peak benefits. Ongoing monitoring and being aware of changes after each shot helps optimize your testosterone replacement regimen.
Pairing injections with a healthy lifestyle maximizes your chances of improving muscle mass, strength, stamina, mental clarity, and overall vitality. Give testosterone replacement therapy time to work and be diligent about tracking benefits and side effects.
