Three patients developed erythrocytosis that resulted in their discontinuation from the study (29). Local and systemic adverse events during subcutaneous administration of testosterone esters (number of events in parenthesis) ARatio of AUC0-168h of DHT and estradiol to AUC0-168h of serum total T at week 6 of treatment.
Rarely, the blood can explode from the injection site like an erupting volcano, immediately after the needle is pulled out. The downside of quad injections is two-fold. Here is another consideration about injections into the glutes. This is a desired area for injection since the muscle in this region has few nerves and few blood vessels and is relatively dense. Another benefit of injecting testosterone into these areas is that there is sufficient muscle to reduce the chance of hitting a significant nerve or blood vessel. The standard areas for intramuscular injections are the buttocks, the side of the thigh, and the deltoid region (shoulder). The third reason for intramuscular injection of testosterone is that this method allows the drug to spread from the injection site at a measured, exact rate.
To inject here, divide the thigh into thirds and use the middle section of the outer thigh as the target site. Much like the dorogluteal site, it is a muscle-rich area with fewer nerves and blood vessels, reducing the risk of pain or complications. This can be to stimulate delayed puberty in male teenagers but is more commonly given to older men experiencing a decline in testosterone.
Serum total A, testosterone; B, 5-dihydrotestosterone; and C, estradiol concentrations after subcutaneous (SC) or intramuscular (IM) administration of 1000 mg of testosterone undecanoate. In this context, SC administration of testosterone undecanoate could potentially be a safer route, because the SC compartment is less vascularized, thus reducing the chance of introducing the drug directly into the systemic circulation. The ultralong-acting ester testosterone undecanoate has been available for IM injection in Europe and Australia for almost 2 decades, and in the United States since 2014. B, Optimal doses needed to maintain serum total testosterone concentration within the desired range were not influenced by participant’s body mass index (bars indicate mean values). Interestingly, the optimal dose required to maintain serum total testosterone concentration within the desired range was not influenced by participant body mass index (Fig. 5B) (28).
Offers more stability and control over the needle, especially for beginners or those injecting large volumes. Fewer reports of post-injection pain or soreness when done correctly (relaxed, slow push). Can also work if weight is placed on the opposite leg to relax the injection leg. How often to inject testosterone? Yes, you can inject testosterone before bed, or any time of day that’s convenient for you. Can I inject testosterone before bed? Some testosterone oils are thicker than others and may require a thicker needle.
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).
