The True Strength of Weight Gainers

Serious weight gain requires serious calories. However, those who need the extra calories most, often have the toughest time consuming enough of them. For many aspiring to be bigger, highly-active metabolisms, weaker appetites, and on-the-run lifestyles make consuming sufficient calories through whole foods alone a real challenge. With Serious Mass, you've got nothing to lose and lots to gain. We've consolidated over 1,250 calories, 50 grams of protein, 250-plus grams of carbohydrates, and 25 vitamins & minerals with added glutamine and creatine into every serving. It's time to stop thinking small; get serious - Serious Mass.


Beyond the Basics

  • 1,250 calories per serving in water; 1,640-plus calories when made with low fat milk
  • 50 grams of protein
  • 252 grams of carbohydrates to support fueling of intense workouts and aid in the replenishment of glycogen stores - with NO ADDED SUGAR
  • Creatine, L-Glutamine & Glutamine Peptides, Choline, Inositol, PABA


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 calories-contributing ingredients and blend for an additional 30-45 seconds. Tips: Mixing two scoops 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 it 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 calories needs in a variety of different ways:


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


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.

Works great! Great tasting and works great! My son is not big on eating a lot to bulk up. And he never feels like eating breakfast. He has been taking a shake every morning for the past year and a half and working out several times a week. He has finally has gained body mass, lean and muscular. Great product at a great price!

Great product to gain weight There was a shock when I brought this product. When you first open the bag, you find a HUGE scooper. The recommending serving size is two scoops a day. I probably only take maybe 3/4 to 1 scoop and then get all my nutrition from food. For someone who wants to put on mass quickly, I think this is the optimal amount as there is no way the human body will digest a serving of 1200+ calories. With that being said, the taste isn't bad at all, and for the price, it's the weight gainer to get if putting on weight is your primary motivation. December 4, 2012
Great product, was able to put on some weight! I got through the whole 12 lbs of Serious Mass in a little over a month. I put on about 15 lbs during this time which is amazing! Prior to taking Serious Mass, I was always around the same weight no matter how much I ate. I'm a typical ectomorph as well so it was very hard to gain weight. Definitely recommend this product to anyone who's looking to gain weight. September 5, 2012
Good product This is a good product; chocolat flavor is OK. I liked the vanilla flavored one more. August 31, 2012
Serving size is huge That "12lbs" bag will be gone in a month if you take it every day. I was looking for the biggest bag for the cheapest price and this seemed like it was it. What I should have been looking for was the greatest number of servings for the cheapest price...then I would avoided this. But then I wouldn't see the benefits of this awesome product....product is great! (not exactly what I wanted, a little deceiving) 4 stars because of deceiving. August 23, 2012
