Alright so, As some of you are aware, some are not.
I work out, have been since my 15th, but like.
I never was able to gain mass.
about a year ago, i weighed 143lbs (65kg), at about 6 ft. (1,90m).
I know, this is ridiculously skinny. but i can't do much about it. my metabolism is fast as fuck. for about a year, i ate 10 to 18 sandwiches (excluding other stuff) a day. with everything on it really. white meat, red meat. fish. you name it.
I gained weight, hardly any mass. and got up to 165lbs~. (75kg).
this took me almost a year.
And seeing as i can't (or barely anyway) gain any mass, and more bulk, when i hardly gain shit. WTF am i supposed to do.
I know some of you know some about training and stuff.
I tried reading websites and stuff. but not much success.
Would love to have some help/info etc.

Keep in mind my extremely fast metabolism. food like, evaporates before it hits the stomach (figure of speech)
