@Nameless eat and drink a ton. Instead of eating aot at once keep eating through our the day in a lower and constant amount. Based on your body and stuff you will have to research about what food is better for and and while you eat try to increase the amount every day. After that exercise and stuff.
@Nameless chicken is obviously the best meat for bulking. But if you have the same problem I do with the protein shakes where it's hard to drink because of the taste, then you can get premier protein from Costco and mix it in with your coffee instead of milk
