Among the many side effects — skin defects (pimples), increased sexual activity, liver problems, aggression and mental instability. Other effects, such as gynecomastia ("bitch Tits"), high blood pressure, other disorders of the cardiovascular system, hair loss, growth retardation in adolescents and the development of prostate tumors (if exists already) can stay, even if steroids are discontinued. Women who use steroids, in addition to this, you may experience symptoms of virilization (acquisition of the properties of the male body) including amenorrhea (reversible process), hypertrophy of the clitoris, deepening of the voice, enhanced hair growth on the body with the simultaneous loss on the scalp and changes in the structure of the skin, sometimes irreversible. Not all steroids cause these problems. Some of the more hard steroids cause these problems only on the part of consumers, in excess of the dose. Some of the milder steroids did not cause these side effects. Therefore, the statement that all steroid users have the same problem, is a mistake. Most of the side effects — the result of the conversion of testosterone to either estrogen or DHT. Many anabolic steroids do not cause this conversion and the side effects they have less.
