Creatine
Creatine is an over-the-counter supplement best known for improving performance in sports involving short bursts of high-intensity activity, such as power lifting, wrestling and sprinting. Side effects include stomach pain, nausea, diarrhea and muscle cramps. High doses of creatine may be associated with kidney, liver or heart problems, and even high blood pressure, although definitive links to severe illness haven't been established.
Although teens may be taking creatine to bulk up, what actually happens is that your muscles draw water away from the rest of your body. The bulking up you experience is often the result of the extra water stored in your muscles, not increased muscle mass. You don't gain extra strength from water. But you may get seriously dehydrated from the redirection of your body's water to your muscles.
The effects of creatine on children and teens haven't been studied. And most studies of adults have followed participants for only a short time — as little as six weeks — so the long-term effects are unknown.
Androstenedione (andro)
Andro is an over-the-counter supplement purchased under the belief that it boosts testosterone production, which will in turn increase muscle mass, energy and strength. In reality, andro doesn't do any of that.
Side effects of andro differ for men and women. In men it can actually decrease the production of testosterone while increasing the production of estrogen. Side effects in men include acne, diminished sperm production, shrinking of the testicles and enlargement of the breasts. In women, side effects include acne and masculinization, such as deepening of the voice and male-pattern baldness. Andro might also stunt your child's growth.

Is there truth to any of this? (That isn't clearly biased in the direction of the 'worried parent'.)
