what is this i dont even
I don't get what you're trying to say here. It can be bad for you in some ways, but here's the rundown on it.
Milk contains lots of calcium, as does practically any mammal's milk. Your bones and teeth, specifically your bones, are made of a mix of calcium and phosphorus. Without said calcium, you get osteoperosis, which is brittleness of the bones.
Milk also contains several different vitamins that you need to process food and such.
But; it contains fat. Fat is what worries quite a lot of people in the sense that it'll make you fat as well. Not necessarily; if you buy skim -> 2% milk.
Now, these hormones you speak of are corporate additives to the cows themselves to make them grow faster, to output more milk. Only incredibly tiny amounts of these hormones actually get into the milk, and you'd get more eating, say, hamburgers or steaks.
Milk also contains large amounts of bacteria, which is killed in the standardized pasteurization process.
