It will be my first real bulk. I am currently 170 pounds @ around 11-12% BF. I am gonna bulk until I'm at least 190, possibly 200. I will be eating clean but eating a lot. Also I will be using creatine for the first time.
How much muscle mass should I expect to gain if I handle this bulk right? My arms are currently 14.5 inches. How much could I expect to gain and how terrible should I expect fat gain to be?
