The injectable form of testosterone therapy (TT) is arguably the most widely known. Oftentimes, athletes choose this form of TT when attempting to build muscle mass because it provides a direct boost of the desired amount of the hormone into the body. In safe clinical settings, physicians must administer the testosterone injection into a large muscle groups like the thighs or buttocks.
Users must re-inject every two to four weeks depending on their dosage and the user’s condition. This means they must return to their doctor’s office every month, as many doctor’s offices rule that users cannot inject themselves. Mandatory rules like this prevents users from improperly injecting themselves, reducing the incidence of overdose. However, this is not to say that all physician’s practice this safety precaution.
Testosterone injections work by directly inserting different volumes of the hormones into the muscle tissues. The hormone-rich solution does not simply remain in the muscle it was injected into – it spreads to the whole body. This form of TT is notorious for its mood-related side effects as the medication initially spreads.
Before the body re-balances itself, users can experience mood fluctuations – not just aggression. The emotional side effects associated with directly injecting testosterone, versus allowing it to absorb slowly into the skin, have garnered negative connotations. However, these mood fluctuations can range in intensity and don’t always impact every user.
