What is the most effective drug to lower estradiol levels? My bone age is 2 years advanced.

Not worth mentioning. At age 19 you are done growing taller and your bone age should be that of an adult. Estradiol has a peripheral role in maintaining bone health but not something I would try to suppress for such a complaint. If you have man boobs due to excess levels you need to have the issue evaluated by your doc. Injected testosterone or medical problems can be the origin. .
