Also, these muscles are massive; therefore, they receive a continual flow of blood, transporting testosterone to the tissues. They are also required when the injection of the drug is too painful to be administered subcutaneously. Testosterone injection is done intramuscularly. We aim to offer cutting-edge international treatment methods with over 25 years of experience in hormonal health, all backed by science and British safe practices. Mike Kocsis has an MBA with a focus on healthcare administration and is an entrepreneur and medical case manager for Balance My Hormones which offers medical services in the UK and Europe. If you are considering starting testosterone replacement therapy (TRT) or wish to get your testosterone levels checked, reach out to Balance My Hormones today for a free consultation. For those experiencing low testosterone, numerous treatment options exist, including testosterone gels and patches. Locate the middle of the muscle by measuring your palm above the knee, then below the greater trochanter. The quad can handle a significant volume of testosterone and is easier to get at than the glute. One option is to have a friend or spouse inject Testosterone. Also, injecting here reduces the possibility of damaging the sciatic nerve, which runs through the buttock's mid-to-lower area. You can locate the peak by feeling the highest bone area above both glute muscles. These areas are suitable since the muscles there are dense. Testosterone cypionate remains one of the most commonly prescribed forms of testosterone therapy in men’s health practice. Compounded medications give prescribers flexibility to tailor testosterone therapy and other treatments by adjusting strength, dosage form, and ingredient combinations to better match individual patient needs. Your TRT injection schedule depends largely on the testosterone ester (e.g., testosterone undecanoate, cypionate, enanthate, propionate) you’ve been prescribed. The best needle size for shoulder testosterone injections is 29G or 27G, 0.5 to 1 inch. The best needle size for quad/thigh testosterone injections is 25G or 27G, with a length of 1 inch or more. Don’t let the fear of needles and injections stop you from adding the powerful tool of testosterone to your anti-aging arsenal. For most folks, the preferred site for testosterone injections is the gluteus medius muscle (glute). During week 7 of the study, the dose of testosterone was either reduced to 50 mg/week or increased to 100 mg/week with the aim of maintaining on-treatment serum testosterone levels within the normal range (27). In another study, 150 hypogonadal men were started on SC testosterone enanthate 75 mg/week for 52 weeks, which was administered via a novel SC autoinjector (27). In 2006, a pilot study demonstrated the feasibility of the SC route as an effective option for testosterone therapy with testosterone esters (23). Recently, after assessing its safety and efficacy, the Food and Drug Administration approved an autoinjector device for weekly SC self-administration of testosterone enanthate (27, 29). In addition, testosterone therapy is used for gender-affirming (hormone) therapy for transgender men to induce masculinization (and suppress endogenous estradiol concentrations in patients with intact ovaries) (2). Therefore, the Food and Drug Administration has recommended that IM administration of testosterone undecanoate be performed slowly by trained personnel in the clinic, and the patient should be observed for at least 30 minutes after injections. A, Serum total testosterone concentrations in 63 transgender men on weekly subcutaneous testosterone enanthate or cypionate. A, Mean serum total testosterone concentrations in men on 50 and 100 mg subcutaneous (SC) testosterone enanthate measured predose (0 hour) and 24 hours post dose. Thinking about testosterone replacement therapy (TRT) to boost your energy or libido? Here’s the safest way to inject testosterone medications. How and where to inject testosterone And that includes injectable testosterone. It does an outstanding job of scaring people half to death and making them reluctant to inject anything, regardless of possible health benefits. Shift weight fully to non-injection leg to prevent muscle tension. Users report successful 3 ml injections with minimal discomfort when sitting and injecting slowly. Most experienced users agree that sitting is safer and more comfortable for quad injections. The best needle size for glute injection is usually 25G or 27G, with a length of 1 inch or more (depending on your size). Below are common injection sites and typical needle recommendations. At Voy, we use 29G or 27G needles for injecting testosterone, as these are smaller needles which tend to be more comfortable. The area under the concentration-time curve for testosterone during the last 2 weeks of the study (weeks 5 and 6 combined) in the 100-mg SC group was similar to that of the 200-mg IM group, suggesting that at steady state the bioavailability of testosterone enanthate is similar irrespective of the administration route (25). Dorsogluteal injections is the most common way that doctors and patients choose to administer testosterone treatment injections. The most common Testosterone injections are; testosterone cypionate, testosterone enanthate and testosterone undecanoate. For testosterone undecanoate, the only study that assessed pharmacokinetics after SC injection suggests that the same dose should be used that is used for IM injection (26); however, more studies with testosterone undecanoate will shed further light regarding the optimal dose for SC administration. Studies involving SC administration of testosterone cypionate or enanthate have used 1-mL Luer-Lok syringes with a 20- or 25-gauge 5/8-inch needle to inject testosterone into the SC tissue of the abdomen or thigh (28, 47). Ratio of 5-dihydrotestosterone and estradiol to testosterone (T) by dose and route of administration during treatment with T enanthate Few studies have evaluated serum concentrations of 5-dihydrotestosterone (DHT) and estradiol after SC injection compared to the standard IM route. Owing to the convenience of self-administration of testosterone esters, the SC route has recently gained popularity. Selection of the administration route of testosterone is influenced by patient preference, product availability, and the cost of the formulation. In the mid-1950s, long-acting testosterone esters (enanthate and cypionate) were introduced, and have since been the preferred testosterone formulation thanks to their affordability, longer half-life compared to propionate, and predictable pharmacokinetics (9). Here we review the pharmacokinetics and safety of SC testosterone therapy with both long- and ultralong-acting testosterone esters. Recently, subcutaneous (SC) administration of testosterone esters has gained popularity, as self-administration is easier with this route. Massey Drugs works directly with prescribers to prepare testosterone therapy based on individual patient needs. If you have questions about testosterone cypionate,, other men’s health compounds, or whether this therapy may be appropriate for a specific clinical scenario, our pharmacists are available to consult.
