-Calorie dense food such as natty PB, olive oil, some fried foods, whole milk
-Perhaps a weight gainer like Cytogainer (personal fav)
-Creatine (retain water)
-Heavy compound lifts only, low reps, no cardio
-Focus on squats and deadlifts
There's plenty more, but those are just a few suggestions.
Credulous at best
Your desire to believe in
Angels in the hearts of men.
But pull your head on out of your hippie haze
And give a listen
Shouldn't have to say it all again
