Testosterone Replacement Therapy: Compare Your OptionsTestosterone Replacement Therapy, or TRT, is the safest and most effective way to treat men suffering from the ravages of age-related testosterone deficiency. But did you know there are different forms of TRT, and they are not equally effective in treating low testosterone?
At The HGH Therapy Doctor, we understand that every man’s hormonal health journey is unique. That’s why we offer several medically proven options for TRT, including the most widely prescribed and effective method, testosterone injections. This page explains everything you need to know about injectable testosterone, the different forms of testosterone available, how they work, and why our doctors recommend injectable TRT and other testosterone delivery methods like testosterone gels, patches, or hormone pellets.
TRT can be prescribed in several different forms. These include topical forms such as creams, gels, and patches, subdermal “hormone pellets,” or testosterone injections. However, our doctors have found that testosterone injections are the safest and most effective way to provide testosterone replacement therapy. Let’s take a closer look at all of these methods and see why our healthcare providers believe that testosterone injections remain the “gold standard” for delivering TRT.
Testosterone gels are rubbed directly onto the surface of the skin. Although easy to apply, gels can pose a serious risk of “transference” to women or children through skin contact or clothing. This can lead to accidental hormone exposure and related side effects in others. Additionally, absorption through the skin is inconsistent and can be affected by sweating, showering, and clothing. Nasal gels may eliminate the transference issues, but they still have not proven to be as effective as TRT injections.
Testosterone patches offer a slow, steady release of testosterone. While they can raise hormone levels, they may cause skin irritation or fall off during physical activity or in humid conditions. Like other forms of topical testosterone they can transfer hormones through contact and often lack flexible dosing options.
Testosterone pellets are surgically implanted under the skin and release testosterone slowly over time. Advocates believe the slow release is closer to the way your body produces and releases testosterone. While they eliminate the need for frequent dosing, they require a minor surgical procedure and cannot be easily adjusted—removing or modifying the dosage means undergoing another procedure. Also, they are available in far fewer dose strengths than injections.
Our doctors have found that TRT delivered via intramuscular injections are the safest and most effective because:
Testosterone injections restore healthy hormone levels by delivering bioidentical testosterone directly into the bloodstream. Once injected into the muscle, the testosterone gradually releases the active hormone, maintaining stable levels and relieving symptoms of low testosterone over time.
Testosterone injections are available in different “esters.” These esters are all forms of synthetic testosterone that differ in their molecular structure. These molecular differences effect the drugs “half-life” or how long they take to work and how long they last in your system.
Testosterone Cypionate
Testosterone cypionate is the most frequently prescribed TRT medication in the U.S. It’s known for its reliable absorption and long-acting effects. Typically administered once weekly, testosterone cypionate maintains stable levels with fewer injections than some shorter-acting options.
Sold under brand names such as DEPO-Testosterone (Pfizer), it is usually compounded in oil-based solutions (e.g., cottonseed or sesame oil) and is available in concentrations of 100 mg/mL or 200 mg/mL.
Testosterone Enanthate
Another trusted TRT option, testosterone enanthate, has a slightly shorter half-life than cypionate, remaining active in the body for around 4–5 days. Injections are usually given every 5 to 7 days. This ester allows for good control of testosterone levels while still offering flexibility in scheduling.
Testosterone Undecanoate
The newest long-acting option is testosterone undecanoate, an ester that only requires seven injections per year after the initial loading doses. Its extended half-life (around 35 days) makes it ideal for men who prefer fewer clinic visits or injections. It is typically administered as a 750 mg dose every 10 weeks following a two-shot loading phase. As of 2021, this ester has replaced Testosterone Propionate as the most popular long lasting form.
Comparison of the Three Main Injectable Esters
| Ester Type | Half-Life | Injection Frequency | Common Dosage | Carrier Oil | Cost |
| Testosterone Cypionate | ~8 days | Weekly or biweekly | 100–200 mg per injection | Cottonseed or sesame oil | $ |
| Testosterone Enanthate | ~5 days | Every 5 to 7 days | 100–200 mg per injection | Various oils | $$ |
| Testosterone Undecanoate | ~35 days | Seven injections annually | 750 mg per injection | Soybean oil | $$$$ |
Though all testosterone esters provide the same hormone, they differ in absorption, duration, and how they are administered. Your provider at The HGH Therapy Doctor will tailor your prescription based on your current hormone levels, symptoms, and lifestyle preferences.
Factors influencing your TRT type and dose include:
TRT injections can:
As mentioned above, our doctors have found that testosterone injections are the most effective method to deliver testosterone replacement. There is such a variety of types and dosages available in testosterone injections that your doctor is bound to find one that is best for your symptoms and lifestyle. And should your dosage of testosterone need to be adjusted over the course of your therapy, that is also very easy with injections. The dosages available in other forms of testosterone medications are far more limited.
Any doctor can prescribe TRT, but that does not mean you should get your testosterone from just anyone. To get the most out of your testosterone therapy, you want to see a doctor like ours who specializes in hormone replacement services.
However, not all hormone replacement therapy clinics and doctors are the same. You want to look for a testosterone clinic that:
