Water Retention:
This is most common from using steroids. It is a “puffiness” or swelling in the neck and facial areas. It is rather notable mainly if you know the person is on steroids.

Acne:
It is a very common side effect, it can give acne to someone who has never had acne, and it can make acne worse for others. It can also appear in new places for a person, such as, the back and neck. There have been several users that have not received acne on the other hand.

Gynecomastia:
It is the formation of breasts, or abnormally large glands. The first signs are lumps under the nipples, then will gradually grow to fatty tissue and increase in size.

Aggression:
Aggression, also know as “steroid rages”. Surprisingly, several athletes feel this is a positive effect. They often find they lift more, and are more intense during workouts. On the negative side, users find themselves fighting with family, friends, and co-workers with an uptight behaviour.

Hypertension:
High blood pressure is also a chance when taking steroids. Most athletes would not know if they had high blood pressure. High blood pressure can lead to many more serious diseases.

Cardiovascular Disease:
Studies have shown that steroid use is a risk factor for heart disease. This is because steroids affect the cholesterol levels. Over a period of time the cholesterol builds up and clogs the arteries.

Palpitations:
Heart palpitations have been reported by a number of athletes on steroids. These may indicate an excited or elevated level of the central nervous system.

Impotence:
Impotence occurs when a user goes on and off steroids. When steroids are first used sexual interest increases because of the heightened frequency and duration of the erections. But eventually the opposite happens and no erections can be produced.

Jaundice:
This is a serious liver disease, which is found by an enlarged painful liver, yellowing of the eyes and skin, and flu like symptoms. This happens when athletes use high dosages of steroids.
