Considering you are a n00b you can see very impressive gain *if* you are true to your word and eat clean and work hard as hell in the gym. I would recommend getting your nutrition dialed in before you even pick up a weight, however. Nutrition is the most important part of the process and you will be spinning your wheels if you aren't educated.
Read the stickies and pick out a pre-made routine created by a professional. Eat clean and work hard and you will see great gains in 6 months.
