Apologies if this should have been posted in the beginner section.
I am 16, 5’10", 145lbs and about 8% bodyfat. I am looking to add mass and right now am trying to figure out a basic nutrition plan:
Should I be taking in more/calories/grams of protein? And just how many grams of carbs should I be eating on a daily basis? I was thinking of going with Grow! Whey for a protein supplement-any reasons not to?
