I’ve used it in the past as well. One thing that I can say for it is that in my opinion, it’s one of the better tasting weight gainers out there. (When mixed with 2%, tastes kinda like a melted Mcdonalds milkshake) I’ve never really had much problem with size, I was just kinda in a bulking phase, and it was cheaper than Pro-Labs Whey. All and all though, it did it’s job quite well. You wanna really see those calories climb. Try mixing it with milk instead of water, and throw in a couple of banana's and/or yogurt for flavor.
