Performance enhancing drugs like steroids can have both beneficial and adverse effects. Glucocorticoids are produced by the adrenal glands and have anti-inflammatory and stress response functions but long term use can cause rebound deterioration and complications. Androgens and anabolic steroids are synthetic forms of testosterone that are used by bodybuilders to increase muscle and bone growth but can cause long term side effects like acne, increased aggression, liver damage, and cardiovascular and reproductive issues.
