There isn't really a magic "get big quick" suppliment. I know that's probably not what you want to hear. A solid workout plan, pleanty of rest, limit alcohol to 1 day/week, and lots of food (4000 - 5000 calories/day is what I ate for months)
To answer you question I take BCAA's, protein powder, and just a basic pre workout supplement.
