It's not about the brand.. If you keep drinking ONLY after workout then you're wasting your money.. your body need calories too on non-workout day..
Mass gainer is just a supplement and IF you don't eat as much as ur body need then you won't gain weight.. You need to calculate ur calorie intake..

Serious mass strawberry is delicious for the first time but now i don't even wanna think about it.. makes me wanna throw up..
