worth it or not ? no, hell no, i would rather eat a variety of food that i like, milo ais, ice cream, chips and shit

but, convenience ? hell yeah, the macros is easy to count since you eat so little variety of food, most of your macros and calories from mass gainer

also you dont even need to cook, just shake shake and can drink

In short, not worth it but very convenient

this is not going to happen. at least to you, and me

research around on what their routines and diet are and see if you can do that, normal person couldn't, and that is why they're famous on youtube and facebook

some of them trained even 2 sessions a day, AM and PM, squat 3x a week deadlift 3x a week

for us, just bulk up and gain strength and try to maintain strength during a cut is more than ideal already
