Query: Don't waste money

I bought this for my boyfriend as he was trying to gain more mass. I was excited to buy this for him.The serving size is 2 HEAPING scoops. I looked for the scoop and it was more like a bowl!! It's 8 oz. of powder per scoop. (I hope you have a big shaker)It was hard to dissolve, if not impossible. Chunky!! Very clumpy.Also a side effect is fatigue after 30 minutes or so. I thought it was just because of the high calorie consumption, but no, it's most likely because of the large quantity of maltodextrin (worse than sugar) in it.I would not suggest this product. Rather use an extra serving of something else.
