Injectable Testosterone:3Options You Should KnowAbout - dreamdragon221 - 07-14-2026
What are the different types of testosterone injections?
Testosterone is an important sex hormone, especially for men. Your body makes it naturally, but it can also be given as a medication. Many people inject testosterone under their skin or into a muscle.
Injectable testosterone has been modified to last for days or weeks in your body. These modified versions of testosterone are called testosterone esters. Testosterone cypionate, enanthate, and undecanoate are testosterone esters that boost your testosterone levels.
These testosterone esters differ in many ways. The most important difference is how long they last in your body. Testosterone enanthate lasts for the shortest time; it has the shortest half-life. The half-life of a medication is how long it takes your body to remove 50% of the medication. Testosterone cypionate lasts longer than testosterone enanthate, but testosterone undecanoate lasts the longest.
Other differences are logistical. For instance, some products must be injected by a healthcare professional. Others can be safely injected at home. Regardless, they’re all options to consider. Let’s look at each one in more detail.
1. Testosterone cypionate
Testosterone cypionate (Depo-Testosterone) is a common form of injectable testosterone. It’s available as a brand-name and generic product, and it’s injected into your buttock muscle every 1 to 4 weeks. You may inject it at home, or a healthcare professional can give it to you.
The recommended dose of testosterone cypionate ranges from 50 mg to 400 mg. Your healthcare professional will pick and adjust your dose. It will depend on your age, how you respond to the medication, and side effects you experience.
Testosterone cypionate, like all testosterone injections, doesn’t work right away. It can take a few weeks for your testosterone levels to increase and symptoms of low T to improve.
2. Testosterone enanthate
Testosterone enanthate is another version of injectable testosterone. It’s administered in two ways.
Testosterone enanthate (Xyosted) is an under-the-skin injection. Other versions are intramuscular (IM) injections.
- Under-the-skin injection: The recommended Xyosted dosage is 75 mg every week. You can inject it into your stomach at home. Your healthcare professional may adjust your dose depending on how you respond.
- IM injection: Many generic versions of testosterone enanthate are injected into the buttocks. You may receive 50 mg to 400 mg every 1 to 4 weeks.
Approved uses for testosterone enanthate
Generic testosterone enanthate is an IM injection. It has more approved uses than other forms of injectable testosterone. Testosterone enanthate can treat:
- Adolescents experiencing delayed puberty
- Adult men with low testosterone (hypogonadism)
- Adult women with metastatic breast cancer
3. Testosterone undecanoate
Testosterone undecanoate (Aveed) is a newer brand-name injectable testosterone product. It’s an IM injection administered into your buttocks by a healthcare professional.
You can receive testosterone undecanoate less often than the other injections. Once your body is used to it, you can go 10 weeks (2.5 months) between doses.
The recommended dose of testosterone undecanoate is 750 mg. After your first dose, another shot is given 4 weeks later. You can receive doses every 10 weeks after your third dose.
Compounded testosterone injections
In some cases, a commercially available testosterone product may not be appropriate. Your healthcare professional may recommend a specific strength or form of testosterone. This is made by a process called compounding.
If your healthcare professional prescribes a customized testosterone product, you can get it at a compounding pharmacy. They can tell you more about what to expect.
The bottom line
There are several types of testosterone injections. These include testosterone enanthate (Xyosted), cypionate (Depo-Testosterone), and undecanoate (Aveed). They offer several benefits, but these injections can cause serious side effects. Use them only if they’re recommended by a healthcare professional.
