"Creatine only helps the most highly
trained and conditioned athletes. Creatine
gives them extra energy so the can work
out longer and harder. Lazy slobs, or even
occasional athletes, who don't have much
muscle or strength to begin with won't
benefit much from taking creatine. This is
especially true with kids who are still
growing. Muscles that grow too quickly
through the use of supplements like
creatine or steroids are more likely to
get injured."
