I want to get taller?

Im 13, in few months I'll be 14. I am 6 foot 2, and 180 pounds. I am 3 inches taller than my older brother, and 20 pounds heavier. He is 15, I am alot stronger, and can beat him up. But, I want to be bigger. I play football, I play left guard on offense, and defensive tackle. I also play special teams, so Im never off the field. Well, this year I am going to a new school. Its a little larger than my last, and I know I will be the biggest on the team, but I want to be bigger. I am the kid you look across the line of scrimmage, and think "Im dead." But, I want to be the even bigger kid that you think, "This kid is like 20." I want to be about 6 foot 7 by the time Im 15. I was thinking growth hormones, I would pay for them. Since I work on roofs for my dads company. I want to be huge, at one point I was thinking steriods, but didn't want to take the chance of "being small downstairs." What can I do to be bigger, meaner, and more aggressive? Should I take growth hormones? Im willing to take risks.
