Testosterone is a hormone that plays a vital role in the body, especially for people who are born male or for those who are taking it as part of hormone therapy. Sometimes, people need to take extra testosterone when their body doesn’t make enough. This is called testosterone replacement therapy or TRT.
There are different ways to take testosterone, but one standard method is through injections. These injections can be given in two ways:
In this blog, we’ll focus on SubQ testosterone injections, which are becoming more popular because they are easier and less painful for many people.
Instead of using a big needle to inject into a deep muscle, SubQ injections use a much smaller needle that goes into the fatty part of your body—like your belly or thigh. This method is often more comfortable and easier to do at home.
Many studies have shown that subQ injections are just as effective as those administered in deeper muscle tissue. A study published in a medical journal found that testosterone levels stayed steady and in the healthy range when people used weekly SubQ injections. People also reported feeling better and liking this method more because it caused less pain (NCBI).
Doctors now often recommend SubQ testosterone for people who want to do injections at home, whether they are men with low testosterone or people who are transgender and taking testosterone as part of their gender-affirming care.
If you need to take testosterone, there are different ways to do it. One way is to inject it into your muscle (called intramuscular or IM), and another is to inject it just under the skin into the fat layer (called subcutaneous or SubQ). Many people are now choosing SubQ injections because they’re easier and more comfortable. Here’s why:
SubQ injections use a tiny needle. It goes just under your skin, not deep into the muscle. This means it hurts less, causes less bruising, and is better for needle-phobic people.
When you use a big shot into the muscle, your testosterone levels can go up and down a lot. That can make you feel tired or moody. SubQ injections help keep your hormone levels more even, so you feel better all week.
In studies, people who tried both kinds of shots said they liked SubQ better. It was easier to do, caused less pain, and made them feel more in control. This means people are more likely to keep doing their shots on time.
Even though the needle is smaller and goes into fat, SubQ shots still give your body the same amount of testosterone. It works just as well as the muscle injections to get your hormone levels where they need to be.
Some people get side effects from testosterone, like acne or sore nipples. These can happen if your body turns too much testosterone into another hormone called oestrogen. SubQ injections may cause less of this than muscle shots.
SubQ shots are safe to do by yourself. Since you’re not going deep into the muscle, you don’t have to worry about hitting a blood vessel or nerve. That makes them an excellent choice for home use.

To administer a subcutaneous testosterone injection, clean the injection site, insert a small needle at a 45-degree angle into abdominal or thigh fat, and slowly inject the hormone. This method offers a gentler, more convenient alternative to intramuscular injections.
In the past, when people needed to take testosterone, they would get shots directly into their muscles.
This was because they needed to inject a significant amount at once, and it would slowly be absorbed into the body from a pool of oil left in the muscle.
However, newer studies have shown that taking smaller doses more frequently can be more effective. It causes fewer problems and helps maintain more balanced hormone levels. Because of this, now it's more common to get testosterone injections just under the skin instead of deep into the muscle.
Choosing between intramuscular (IM) and subcutaneous (subQ) testosterone injections depends on various factors, and each method has its advantages.
Subcutaneous injections, where testosterone is injected just under the skin, are becoming more popular, especially for testosterone cypionate, due to several reasons:
The injection angle is essential for sub-Q injections to ensure the medication is delivered just under the skin.
However, IM injections, where testosterone is injected deep into the muscle, are still preferred for certain types of testosterone, like Sustanon and Enanthate. These formulations contain preservatives that can make subQ injections more painful. Large-volume injections like Nebido (4ml) are also unsuitable for subQ injections due to the large volume. In individuals with a higher body fat percentage, the effectiveness of subQ injections may be affected due to the presence of more fat tissue.
Sub-Q injections are often recommended for small-volume injections (less than 0.4ml).

Remember, proper hand washing is crucial for preventing infections.
Injecting into the abdominal fat region is advisable due to its lack of nearby structures, such as blood vessels and nerves, minimising the risk of accidental injury. Additionally, this area typically has a sufficient layer of fatty tissue under the skin, preventing injections from going too deep beyond the subcutaneous layer. The abdomen is conveniently accessible and visible, facilitating easy administration of injections.
Administering a subcutaneous injection in the thigh may be slightly less comfortable compared to the abdomen, particularly for men who have less body fat in this region.
To locate the appropriate site, divide your thigh horizontally into thirds. The injection should be administered in the outer middle third, situated midway between the knee and hip along the first part of the thigh.
While this area may not be ideal for men with lower body fat levels, it could be a viable option to consider when rotating injection sites.
Here's how to get your injection dose ready in a more straightforward way:
Check Syringes and Needles: Ensure your syringes and needles packages aren't opened or damaged. If they are, don't use them because they're not sterile.
Opening The Ampoule (For Enanthate): If you're using Enanthate, hold the ampoule and snap it open like you're breaking a small stick. Aim to break it at the neck, right below the dot. It's the thinnest part, so it should snap easily.
Preparing The Vial (For Cypionate): If you're using Cypionate or a vial, you can use it more than once. Grab the vial and clean the rubber top with an alcohol swab.
Syringe and Needle: Open their packages carefully, ensuring they do not touch the ends of anything, including your skin.
Getting Rid of Air Bubbles: Once you've drawn the testosterone, check for air bubbles in the syringe. If you see any, tap the syringe gently to move the bubbles to the top, then push the plunger to expel the air. It's okay if a tiny bit of air remains at the top.
Switching Needles (For Ampoule Users): If you used the big needle to draw from an ampoule, now's the time to switch to a smaller needle (27G, 29G, or 30G). Don't take the cover off the new needle until you're ready to inject.
Double-check the Dose: Make sure the amount in the syringe matches what your doctor prescribed. Ask your doctor or healthcare professional for help if you're unsure.
Remember, keeping everything clean and not touching the needle or syringe end is critical to a safe injection.
Can I give myself a subcutaneous testosterone injection at home?
Yes, you can safely give yourself a subcutaneous testosterone injection at home with the right supplies and training. Many people prefer this method because it uses a small needle and is easy to do in the belly or thigh area. Always follow your doctor’s instructions for subcutaneous testosterone self-injection steps.
Does subcutaneous testosterone work as well as intramuscular injections?
Yes, research shows that subcutaneous testosterone injections are just as effective as intramuscular shots. They help maintain stable testosterone levels over time and may reduce the frequency of hormone fluctuations. Many people switching to subcutaneous testosterone therapy report better comfort and similar results.
How often should I inject testosterone subcutaneously?
Most people inject subcutaneous testosterone once or twice a week, depending on the dose and their body’s needs. Your doctor will decide how often you should inject based on blood tests and symptoms. Using the correct subcutaneous testosterone injection frequency is key to getting stable levels.
What’s the best needle size for subcutaneous testosterone?
The best needle for subcutaneous testosterone is usually a 25 or 27 gauge needle that’s ½ inch long. This size helps you inject into the fat under the skin without pain. Using the correct needle size for testosterone SubQ injections makes the process easier and more comfortable.
Where is the best place to inject testosterone subcutaneously?
The most common subcutaneous testosterone injection sites are the lower belly (about 2 inches from your belly button) and the outer thigh. These areas have enough fat to absorb the medicine well. Rotating your testosterone SubQ injection site each time helps protect your skin.
Can women or trans men use subcutaneous testosterone injections?
Yes, subcutaneous testosterone is commonly used by trans men as part of gender-affirming hormone therapy, and sometimes by women with low testosterone levels. It’s a safe and effective method for different people who need testosterone. Studies well support subcutaneous testosterone for transgender hormone therapy.
What are the side effects of subcutaneous testosterone injections?
Side effects may include mild redness, swelling, or itching at the injection site. Other side effects could consist of acne, mood changes, or oily skin from rising testosterone levels. Most people find that side effects from testosterone SubQ injections are mild and manageable with proper care.
Do subcutaneous testosterone injections cause less pain?
Yes, they usually hurt less than intramuscular shots because the needle is smaller and penetrates the fat instead of the muscle. Many people say SubQ testosterone injections are more comfortable and cause less soreness afterwards. This makes testosterone injection for low testosterone easier to stick with.
