If you are consistent, you will gain weight. At first it seems it's a little upsetting on the stomach, as it is not used to the amount of liquid calories you throw at it, but with time you will adapt to the routine and start gaining that magical mass. Drink one scoop in the morning with breakfast and drink another one hour before bed. And ofc don't forget to eat your regular meals. From 154lb I went up to 170lb in the matter of 2 months and I am just on my second bag.

Started out with the Chocolate Peanut Butter. Good flavor but results were slim to none. Decided to give it another chance and picked up Chocolate recently. Not sure if the formula changed but the shake became a lot more foamy and caused me to throw up the past 2 times I took it......not to mention, it tastes like dirt and asphalt.

I've been taking these shakes for a few months now and have gained 20 pounds since October. I weighed 148 pounds in October and now I weigh 169 pounds. The chocolate and vanilla flavors are pretty good, the chocolate peanut butter flavor is good too, but I prefer the chocolate the best. The best way I have found to make these shakes is as follows. 24 oz whole milk, 2 heaping scoops of chocolate powder, 1 banana, 1/2 cup of oats. Blend thoroughly. 1980 calories and it tastes good!

An absolutely brilliant mass gainer, the flavours are far superior to other supplements I have used in the past. I would recommend this product to anyone looking to gain some "serious mass" and quick. Bodybuilding.com never fail to impress with their fast delivery, quality and overall service.

The taste is great. I gave Vanilla a 7 because after mixing, half is turned to froth. I have asked a few friends that have used this and they said it was only the vanilla for them as well. Other than the frothiness of vanilla, this is a pretty rad product in my opinion

I am almost done with my first bag, I chose vanilla and gave it a 10 because you can change the flavor of vanilla, me personally I like to throw in 2 scoops of peanut butter 1 whole milk and one chocolate milk into the blender takes care of the not mixing well part, sometimes I mix with coffee or orange juice, vanilla has endless possibilities. I was taking 1 to 2 scoops a day and did a 4 week run working out 5 days a week and I put on 12 pounds, seen 180lbs on the scale for the first time in my life. Got home after a month and girlfriend for the first time made the comment how good and muscular I looked, now I'm buying multiple bags...my only negative review is I did really have to watch my gut, but hey I guess that's part of gaining weight and bulking.

Directions For Serious Mass:

Add two heaping scoops of Serious Mass to a blender filled with 24 oz (710 mL) of water. Blend for 45-60 seconds. Then add a few ice cubes and, if desired, other calorie-contributing ingredients and blend for an additional 30-45 seconds.

Tips: Mixing two scoops of Serious Mass with 24 oz (710 mL) of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake. New users may find if beneficial to begin with 1/2 of a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.

Serious Mass is a substantial weight-gain supplement that can be used to feed serious calorie needs in a variety of different ways.

Between Meals: Drink 1/2-1 serving of Serious Mass between meals to maintain positive nitrogen balance and support a high-calorie diet. Post-Workout: Begin drinking 1/2-1 serving of Serious Mass 30-45 minutes following exercise to support maximum recovery. Before Bed: Drink 1/2-1 serving of Serious Mass about 45-60 minutes before bed to provide nutrients to recovering muscle throughout the night.

Note: For best results use Serious Mass combined with intense weight training (3-5 times per week) and a sensible whole foods diet. Also, keep in mind that sufficient recovery between workouts impacts your ability to gain lean mass. Allowing at least 48 hours between workouts involving the same body parts is recommended.

Warnings: Keep out of reach of children. Do not take this product if you are pregnant or nursing a baby. Check with a qualified healthcare professional before using this product if you are under 18 years of age or if you have any known or suspected medical condition(s) including diabetes, hypoglycemia, and/or if you are taking any prescription or OTC medication(s).
