The rest of you can look at it, but I can't advise you use it, because the interplay of both estrogen and testosterone is very necessary during development, through age 20-22.
There is something you can try: supplementing with inositol and glucuronolactone, both of which aide in the removal of estrogens from the body.
This is a mechanism the liver uses for control of estrogens - after they are produced. The natural compound medley in Aromastat addressed aromatase conversion enzyme that produces excess estrogen in certain tissues.
The combination might be useful for severe gyno, in mature adults.
The best course of action for young men is to wait patiently, as the great majority of these cases spontaneously resolve themselves without chemical intervention. The problem in using an approach like aromastat is that you don't know when you might be inadvertantly acting at the gene level by what we call permiscuous binding of ligands to gene receptors. Thats the reason that I can't recommend its use. I post this link purely as a service for adults whose symptoms have failed to regresss and fade over time
