I am not really familiar about what is the best thing on the market. i dont know what i should take, i was thinking about taking Sus. but im not sure. I have a hard time gaining weight and ive been working out for over a year and i see little results. i have tried alot of things on the market but i still see no results. I have pretty intense workouts and i am getting fustrated.

I am 6' tall
160LBS
I am 20 years old and want to get around the 180lb mark.

I was wondering what is good to start with and how much everything will cost. If you guys can please help me that would be great. I dont want to be a monster just look pretty decent, i am ripped now but thats it i can't get bulk.
