So I joined a gym...

it will take up to 3 months, depending on what you eat, how your body functions, to build up the muscle strength and mass for your upper part of body. once the muscles have reached to it's maturity you can start focusing on the muscles you want to build and cutting them up. if you want quicker responses, buy a blender and make yourself protein shakes everyday. i used to cheat by adding 2 spoonful of creatines per shakes, but it seriously fucked my already fucked up ankles up so i stopped cheating.
