Testosterone enanthate is a steroidal hormone derived from testosterone. It's usually administered through an injection into a muscle where it may then disperse into the body. Though not as commonly used as other steroids, it treats people with male delayed puberty, metastatic breast cancer and hypogonadism, which is a condition where the testicles produce little to no testosterone. As with almost any type of medication, testosterone enanthate isn't without its own set of side effects.
Male Side Effects
One of the main side effects of testosterone enanthate in men is an increase in the frequency and duration of erections, according to the Food and Drug Administration (FDA). These erections aren't necessarily caused by arousal or stimulation and may become painful. It's also possible to develop male pattern baldness and acne on the face, neck, shoulders and back. During the course of treatment, the body may adversely react to the testosterone enanthate by causing the skin to feel some level of numbness, tingling, prickling or even burning. You may also notice a change in your libido, emotions and reactions to stress.
Female Side Effects
For women, one of the more common side effects of testosterone enanthate is menstrual irregularities; menstruation becomes more or less frequent as well as heavier or lighter than normal. You may also notice a change in your voice, taking on a certain level of hoarseness, as well as the development of facial hair. Much like men, you can encounter a change in your libido, emotions and reactions to stress.
Other Side Effects
Both men and women may experience a fairly serious side effect involving their health. Through its use, testosterone enanthate increases cholesterol levels, which can put you at a greater risk of developing coronary artery disease as well as suffering a heart attack or stroke. This steroidal hormone may also cause nausea, upset stomach, vomiting, headaches, bloating (due to water retention) and joint pain (due to inflammation). Sometimes, it can affect the way in which your blood clots, which could cause blood loss and lengthen healing time of wounds.
