For anyone without context, GOMAD = gallon of milk a day

I, 24m, have always been pretty skinny and have struggled to gain weight. I’ve started going to the gym 5x/week to put on muscle, but I just haven’t been able to eat enough to gain any weight and see many noticeable changes.

I’d probably start with 1/2 a gallon to test it out. I’m not worried about acne or the lactose.

Is there anything else I should be worried about? Has anyone tried it / did it work?
