Normal levels of testosterone are between 300 and 1,000 ng/dL, however, over the age of 40 men can have blood tests that show much lower levels than the norm. This may call for specialized therapies known as testosterone injections.
Testosterone injections are commonly inserted into the buttocks or thigh. These areas tend to be easier for people to handle pain and thus (depending on the dosage), patients can take testosterone injections for weight loss up to 4 times per month. This type of testosterone therapy is common for people who experience feelings of lethargy, exhaustion or simply desire extra support to achieve their best body.
