At this point I do not recommend anyone younger than 18 to use creatine except under medical supervision. If your personal physician and parents approve your use of creatine, it should only be taken for a brief period of time, such us a couple of months for a particular sports season, and then you should be off it the rest of the year. Daily dosage is best kept to 3 gm, with two days off per week.
I am uncomfortable with teenagers using creatine without supervision since they often do not know their limits. My website gets frequent emails from parents wanting to know whether creatine is safe for their teenage son or daughter.
Since creatine is readily available over the counter, it is unlikely that we can prevent teenagers from using it. Therefore, a "Just Say No" policy won't work. What we can do, though, is have a balanced viewpoint and encourage communication between teenagers, parents, coaches, and a physician.
I am definately against teenagers using hormones.
