I was hanging around 175 lbs, ~9 - 10% body for years. My workout involved mostly free weight exercises, but weights grew slowly. So one day I thought enough is enough, and decided to change my diet and bulk up. To grow, I needed to increase my caloric intake up to 4500 kcal. I found that serious mass provided an easy and convenient way to supplement your diet with necessary calories.

With 1250 calories in two large size scoops, I found convenient to split a servings into two, taking one between breakfast and lunch, and second one before workout. Even one scoop requires plenty of water or milk to mix, but regular shaker will do just fine. I never tried to consume one serving (2 scoops) at once, and I don't think that makes sense - it is more efficient to eat smaller meals more frequently. Plus, 50 grams of protein will never be properly digested in one serving, so you are better off consuming a scoop at a time, several times a day.

I have first ordered a bag of banana flavor, and found it too sweet. Double chocolate is pretty good, and I kept using it afterwards.

In 4 month, I have went up to 200-205 lbs, and body fat ~16%. Squat, deadlift and bench press numbers all showed steady increase; for instance, deadlift went from mere 235 to 360 2RM, benchpress increased from 185 to 245 5RM. Results are obvious - with appropriate training regimen this product works.

Now, let me respond to some reviews here. Some say, it does not mix well. My response - don't mix two scoops at once, that's not efficient.
I don't understand how 'gained some fat' is a con - this supplement is designed to make you grow. It is impossible to add muscle without adding some fat tissue as well, read literature.
Finally, my favorite - large scoops! Well, there is 1250 cal with 50 grams of protein. Not surprisingly, that takes up volume. Its a big boy supplement, and it has big boy scoops.

Overall, Serious Mass provides excellent way to increase caloric intake during bulking phase. When combined with appropriate resistance training, allows you to grow muscle more efficiently.
