Great product. I struggle to gain mass and have tried various mass gainers which have all been sub-par when compared to Optimum Nutrition's Serious Mass. Top quality for the price, and great tasting.

Since ON make one of the best whey protein powders, I thought I give their mass gainers a try during my off season and purchased aChocolate Peanut Butter. Cant fault anything on this. It mixes very well and works excellent with my protein pancakes. Plus it really tastes like Chocolate Peanut Butter. I have seen excellent results as well. Would recommend.
