....Help wanted....

I´d like to gain 10 Ibs the nearest 3,4 maybe 5 months naturally, no AAS included!!
I know it´s not impossible. Everything is possible it´s just a matter of dedication, preparation and time & effort.
But, today my bodyweight is 204Ibs and I would like to get some opinions regarding how many carbs and how much protein you would suggest me to take...

I´ve read figures claiming 2 grams of carbs / Ibs of BW and 2-3,5 grams of protein / Ibs of BW...and as always I like to ask questions and get second opinions about most things before I settle myself for the tough quest of gaining as much musclemass as possible without gaining too much fat

Of course I´ll gain some BW including fat, but I don´t want to look like a seal on land, I´d like to look like I still work out. Even tho' I´m in a 'mass gain mode'
