estrogen related sides?

hey guys
just wondering what all the possible estrogen build-up related side effects could occur? i know about gyno and water retention already, but there must be more? does anyone have a list? i don't mean all the sides of roid use. i mean just the sides for the estrogen that builds up from the conversion process. thanks.

i think acne???but not sure so.....BUMP

estrogen related fat deposits is another one i suppose

add elevated blood pressure to the list as well

estrogen will give you smooth skin, at least my girlfriend has nice skin anyway.. Look at Micheal Jackson that is a good example.. :)
