The important thing to realise when training to gain muscle is that the Monster Mass Review  rate of improvement at any given time is i) subjective and ii) dependent on the level of the athlete in question. That means that if your friend is growing faster than you, that doesn't mean you're necessarily doing anything wrong and that if you're a beginner in the weight room you should be able to progress much faster than if you had 5 years training under your belt.

For a beginner who is looking to pack on serious amounts of mass in as short time frame as possible I suggest taking a logical approach of 1 to 1.5lbs per week in progression on the scales. That should equate to roughly 500 calories in excess per day of what you require to maintain. It is extremely important for you to realise that if you start to eat way in excess of your body's requirements, the process for building muscle doesn't speed up beyond a certain point. In other words, if you stuff your face, you'll get fat, not muscly.
