Steroids are used by both male and female teens to lose fat, increase muscle mass, and gain strength and endurance.
Teens don’t realize that side effects can include stunted growth, aggressive behavior, trembling, severe acne, aching joints, premature baldness, high blood pressure, liver damage, cardio-vascular damage, damage to reproductive organs, impotence and infertility.
Most steroids are obtained illegally and lack any quality control.

Steroids may be contaminated, mislabeled or bogus.
