Realistically, it will take roughly 12-18 months to put on and keep that as actual muscle with low; 5-7% BF (2-4% pre-contest). Are you in your 20's or 30's. This is an important consideration as well.
I gain about 15lbs of solid muscle per year. 31lbs in the last 21 months to be exact. I am 220 now but it has been as high as 232. The more pure muscle you have the harder it will become to gain a lot of fast weight. What happens is the quality and density improve, and the quality not quantity scenario comes into play. Patience is key at this point. Here's the math I did for my gains timeline. 15lbs per year x 5 years= 75lbs lean mass. I have been training very strictly for nearly 2 years and gained 31lbs of muscle that I never had before. 2 years x 15.5= 31lbs+189lbs starting weight = 220lbs. At the current rate of gains, I will peak out at the 7 Year mark at a weight of 295lbs at 3%-7% bf. At 5 years (2020) , I should weigh around 270lbs. My goals are very high reaching, but that is who I am. I strive to be a champion in all aspects of life. Still working on it though. LOL.
The purpose of these calculations for myself is primarily to remain realistic as to my goals being actually reached. Also it gives a measurable rate at which you can monitor progress and know with confidence, that you are on track. It can get discouraging to feel as if you are plateauing, but these sort of hard numbers will bring you confidence and restore drive. Once you see your long term progress and how much you have actually changed your physique it can be revival.
Post some info about your weak points and where you want to come up. Physique wise and discipline wise. The gym is worth only about 20% of your kept gains. Homework is where you put on and keep muscle. The gym is for stimulating a growth inducing environment and opening our anabolic window. Another thing that helps me grow faster and keeps the gains going up; is to eat clean until you just can't hold anymore food. Calorie counting is for cutting and prep; not bulking. Eat like an elephant and you will grow like there is no tomorrow. If you you are training intense and heavy, you will not get fat. In fact your body will be using more fat for cellular energy uptake. Because of this you will need MORE fat in your diet to build all the muscle. Fat and oils are anabolic and make up our hormones. Greasy and lardy foods are what you need to stay away from on a bulk. To many triglycerides will shut down your anabolic furnace temporarily and slow results. If your body runs out of carbs and fat on a bulk it will take it out of the muscle along with protein, for functioning. This is how most muscle is lost. Protein deficit sets in about every 2 hours for an athlete. This is why you must eat at least every 2-3 hours. No exceptions or gains will for sure be lost. We lose the most muscle when we sleep for 8 hours without protein. So load up before bed or set the alarm for a 3 am power shake.
Post more detail about goals and training. Where do you need the muscle at most to win. That's where you need to train until it comes up. That is also why so much time is needed. Every group of muscle needs individual attention and focus in order to progress and mature. In bodybuilding we are attempting to complete the genetic development process and gene expression to it's absolute full potential. To actually change your residual self image in to what you visualize it to be. This is the maturation process and also taking the lead in your development and overall health, and to lead by example. And become superhuman of course. LOL
