Hormones, like testosterone (T), and receptors are very similar to keys and locks. Testosterone binds to “androgen receptors” all over the body to send essential messages, start and stop vital bodily functions. Although testosterone (T) can be found in men, women, children, and other animals, it’s the primary human male sex hormone.

T regulates growth phases, controls the metabolization of food into energy, enhances sexual function and development, stabilizes mood, and plays a significant role in other physiological processes.

Bound testosterone is already attached to proteins, meaning the body can no longer use it. This is why free testosterone is so important in maintaining homeostasis, which are the optimal conditions of internal, physical, and chemical balance.

When free T levels drop too low, below 300 ng/dL, men can experience a wide range of uncomfortable symptoms due to a condition called low testosterone (low T) or hypogonadism. Some of the common symptoms of low T include low sex drive, hair loss, fatigue, weight gain, and mood swings. Low T affects as many as two to four million adult men in the US.

Testosterone Injections and Low T

Ever since the FDA approved testosterone injections as a therapeutic answer for hypogonadal men, it has continued to grow in popularity. According to one study published in JAMA Internal Medicine, 10 million men ages 40 and older have used testosterone therapy to alleviate the symptoms associated with low T.


Factors like age can deplete testosterone levels over time, but testosterone is one of the essential components for metabolizing carbohydrates, fats, and proteins.

That’s why men with low T may notice physical changes like weight gain and loss in muscle mass. Low T chips away at fat-free mass in men, and increases fat accumulation, causing muscles to shrink and fat deposits to expand, especially in the abdomen.

Testosterone injections can restore muscle mass and performance. In a study following 370 adult males during low T treatment, participants performed better in upper and lower extremity strength tests and increased their lean muscle mass during the experiment.


The brain also contains androgen receptors that bind with T cells to control mood and promote an overall sense of well-being. The emotional and cognitive effects of low T cause many hypogonadal men to experience mood swings and depression, especially if they are 50 years of age or older.

Studies have found that testosterone injections for hypogonadal men can reverse irritability and fatigue, enabling clients to feel like themselves again.

After researchers followed 51 men with low T during two months of therapy, the participant’s self-reported incredible improvements in mood indicators like energy, good feelings, and friendliness, as well as a decrease in negative indicators like anger, anxiety, and irritability.


Since testosterone is the primary male sex hormone, abnormally low levels can drastically impact sexual health and function. Men can experience a decline in libido, along with difficulty producing and maintaining erections.

Erections are created by a series of chemicals, including nitric oxide. Testosterone affects the body’s ability to produce enough nitric oxide for erections, which is why T injections can reverse erectile dysfunction in hypogonadal men.
