Basically all you need to do is eat a surplus of calories and lift heavy to put on mass. For me 50-100g of protein a day is enough, but he might want a little more if he's eating 5000 calories. Aim for 10% of total calories. He should be getting a minimum of 600g of carbs a day and roughly 30-40 grams of fat. Try and get him to focus on whole fruits, vegetables, and starches like rice, beans, corn, oats, pasta, potatoes, etc...
Trying to build good aesthetic muscle all over your body without taking AAS is not possible.
All the protein in the world won't do much unless there is enough exogenous AAS to increase protein retention and synthesis.
I think you are wasting your time Elyse. This dude aint serious about it. Better to find a vegan swoldier already doing it.
True. No roids = no aesthetics. No photoshoots, social media following, etc.
But if he's young, eating a lot, and training properly he can surely add some lean mass.
Pineapple, bananas, beans, white rice, sweet potato. Soy food and protein powders in moderation. Fructose increases feed efficiency in studies done on cows.
