I would say you wait a little. Wait till your body is more developed like around 17yrs. No point in putting all those supplements into your body. Creatine is just gonna make you light heavier and what does lifting heavy do to your body at your age? it may interupt your growth porcess. I heard it also shrinks your nuts.... jk.. lol. No but at your age i say go natural food for a while.
Isn't it kinda late to ask now that you've taken it. Your diet should be perfect before you start taking creatine...and then there's the whole body development thing as well.
