P90x. I am 5’9″ 140lbs and about a week and a half into p90x.?

How much weight or muscle mass will I gain if I do the workout routines? I want to get to 150lbs with muscle is that possible?

It is very much possible..

Stick with the routine. Be serious and motivated.

Supplement your workout with proper diet and protein shakes, you will see results in 30 days.
