Is it def pubertal gyno or is it fat? If it is fat, that is a tough area to lose it in and is the last to go. I have struggled with that my whole life. If it is gyno then I am not sure that taking anything is really going to reverse it. A lot of the protocols followed are for when you develop the early stages of gyno and it can be reversed. You are way to young to consider cycling and should really put your time into studying the information and diving into the diet section to learn how to eat for maximum results.
