Add two heaping scoops of Serious Mass to a blender filled with 24 oz 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 fl. oz. 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.

Add two heaping scoops of Serious Mass to a blender filled with 24 oz 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 fl. oz. of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake.

Serious mass is a great mass gainer. Don't think I've seen another with more calories but taking the prescribed amount of powder is a huge shake. Only downfall is that it's high in carbs and sugar. If your a hardgainer this is definitely a protein powder for you. You will lose some definition but will visibly put on the extra pounds. Mixes pretty well in shaker but does have clumps, taste great, much better with milk then water. Enjoy*

This mass gainer is probably the best gainer out there today, the only issue I have with it is that you definitely need a blender for two scoops. Also it takes a like two or three days to get used to taking the two scoops after you lift. I recommend highly taking a product with bcaas in it also. For example I take recon by muscle pharm right after I lift then I'll take serious mass. Great combo for gaining mass in my opinion.*

I recommend this product to anyone looking to increase their weight by bulking. Taste is good even though there are clumps sometimes left over, but i wouldn't call that a drawback since you want the nutritious side of it. Serious Mass intake of protein, carbs and calories are solid when looking to bulk. I've used one 12lb bag have gained 6kg of mass in just less than two months. My weight was 65kg to 71kg. However i did not use the directions for consuming this mass gainer, i only used one scoop instead of two and only took it post workout, which is 4 times a week (Only started taking it once everyday day on the last very few kg left in the bag). My body has substantial definition in muscles and i wanted to gained mass by bulking and i have kept the tone while building more mass using this product. My recovery time has decreased now and my body feels more anabolic in building muscle due to the calorie intake. Still should be used with a solid diet approach. A solid weight resistance routine as well if you want to build substantial mass, as you want the high calorie intake to be used in muscle building and not just being stored as excess calories. I add Glutamine supplement powder with my Serious Mass to maximize recovery and minimize muscle catabolism and maximize protein metabolism. So far it has worked great. I have another 12lb bag on the way and this time ill will be taking one shake a day and i will expect more kg/lb gained than my last result of once per post workout. Recommended.*

I am just beginner in weight lifting (4 months since I started) and have typical ectomorph body. I hardly gained weight even though I was doing moderate to heavy weight lifting and followed a good diet. It's been nearly 2 weeks since I started using Serious Mass and have already gained 2 kgs !! Ofcourse don't be under impression that stuffing Serious Mass will automatically help you gain muscles .. you still have to push yourself hard in gym. In my case I started noticing that I was able to start lifting bit more heavy or was able to increase my repetitions. As for the Serious Mass dosage I take 3/4th scoop early morning with water i.e. immediately after I wake up ... 1 scoop again with milk post workout and 1 scoop with milk again before sleep. As mentioned by other guys ... you have to use blender to make smooth shake.*

Great price per calorie, no added sugar. Taste is solid. A blender is a must, as it mixes poorly in a shaker.*
