You get what you pay for...I was in a pinch and low on money so I couldn't afford my usual go to So I figured I'd give it a try I knew going in after reading the nutrition facts it wasn't the best ingredients but it's what I could afford and I have had worse over the years So 12lbs for 30 couple bucks.. You would think though with almost as much sugar as a soda it would taste better just saying.*

Purchased the first bag on sale for my son and at a price worth trying out. The mass gainer served its purpose, and he liked the vanilla flavor good enough to order another bag. *
