Ok, so I am 25 years old, 5'11 190 pounds male. I use to be a real fatty until i had gastric bypass and lost like 150 pounds! Now I am left with a smaller body with no muscle and want to build muscle to my body without really gaining weigh. I just want to be muscular at the weight I am at now. I need to know what steroid I should take to do that? How long should I take them? Are steroid really as bad for you as people say? Is dick my going to shrink? I just need some help with this stuff. I don't have a clue what I am doing.
