The huge concern is that many people don't realize that estrogen is a very important hormone in males from fertility, lipid health, cognitive function, etc. Guys get on here and think that if they crush their estro year-round they will stay lean, dry, etc. It's not smart to just decide you want to take pills to lower your estro year-round without actually knowing if you need to. For some it may be wise and healthy, but not for the masses.
