Serious Mass

Optimum Nutrition makes a weight gain/protein shake called Serious Mass. This stuff works too well. I used this for less then 3months and I gained 30 pounds.
Some of then ingredients are not the best for you. With that many calories the only reason you should take this is to gain weight. It does contain a lot of vitamins and protein but I would only use it to gain mass.


The things it promises:
Adding Calories Has Never Been This Easy or Tasted So Good
1,250 CALORIES
50 g of BLENDED PROTEIN
Over 250 g of Carbohydrates with NO ADDED SUGAR
Enhanced with Creatine, Glutamine, and Glutamine Peptides
25 Vitamins and Essential Minerals

It promises to gain you size and that is exactly what it does.

Price:
It comes in 3 sizes the smaller sizes are not worth it. The scooper is huge and it is really easy to go threw a large amount very quickly.

3pound - not worth it. 

6pound - I started with this. It lasted a while and I gained at least 10 pounds just from this bottle.

12 pound - If you are looking to gain a huge amount of mass get this size.

Overall score: -------------- 70 --------------

I bought two 12pound bags and I got to my target before I finished the 2nd bag. Be careful to use when working out, if you start using it as a meal replacement and use it when not exercising you will gain a lot of unwanted fat.

Flavors:
Banana: I got this one in a 12 pound and was choking it down for a few months. Its ok but vanilla and chocolate are much better tasting.
Chocolate: Probably the best of all flavors. I only used this flavor once because they dont sell it as a 12 pound.
Vanilla: Can get bland and hard to swallow.
Strawberry: I do not suggest this one it was really hard to drink.
