Go with the doc's script. Anyway the body will only absorb what estrogen it can handle and it gets rid of the rest mostly through your pee. So the more you take doesn't mean quicker results or the more e in your body. The body as a natural way of dealing with hormones and balances and regulates its self, cool stuff, hay.
No reason to risk taking more because it isn't going to do any good.
