    Optimum Nutrition - Serious Mass Banana - 12 lbs. (5,455g)

    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. Optimum Nutrition has consolidated over 1,250 calories, 50 grams of protein, 250-plus grams of carbohydrates, and 25 vitamins and minerals with added glutamine and creatine into every serving. It's time to stop thinking small; get serious – Serious Mass.

    Beyond The Basics

    • 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

    About Optimum Nutrition
    Optimum Nutrition, Inc. (ON) is a wholly owned subsidiary of Glanbia, a leading international cheese and nutritional ingredients group. ON owns and operates two brands of nutritional supplements (Optimum Nutrition and American Body Building) providing a comprehensive line of products across multiple categories. With state-of-the-art production facilities occupying over 500,000 square feet of operating space, ON is the only sports nutrition company to manufacture items in every product category. Whether it's nutritional bars, protein powders, ready-to-drink sports beverages, or vitamins, essential minerals, and herbs, Optimum Nutrition is able to control the integrity of all products through in-house manufacturing. Supported by Costello's Health Distributors (Optimum Nutrition's sister distribution company) and ABB's nationwide direct service distribution network, customers are ensured prompt delivery and unmatched customer support.

    Collectively, Optimum Nutrition, American Body Building, and Costello's Health Distributors, are the dominant force in the sports nutrition industry with the highest quality products available in health food stores, specialty stores, gyms and progressive retailers everywhere. HistoryOptimum Nutrition was founded in 1986 by brothers Tony and Michael Costello. Originally known as Costello's Health Distributors, the entrepreneurial brothers soon recognized an opportunity in the need for significantly improved quality and innovative vision in the sports nutrition industry. The Optimum Nutrition brand was launched to satisfy both demands, and after 22 years of success reflected in great part by the ongoing best-selling status of ON Gold Standard 100% Whey, the Costello's entered into agreement to sell the company to the international cheese and nutritional ingredients group Glanbia.

    Optimum Nutrition Mission Statement
    Optimum Nutrition strives to produce distinctive, affordable, premium-quality products while making every effort to anticipate ever-changing customer needs and meet the demands of a dynamic market with innovative products, effective support materials, and unsurpassed service.

    As an advocate of healthy lifestyles, ON believes that every consumer should be able to purchase premium products; so they eliminate the middlemen and control the integrity of their brand throughout the entire production and distribution processes, making sure each product is not just top quality, but also among the most competitively priced in the industry.

    Quality Counts
    Optimum Nutrition's commitment to quality is evident throughout the entire product development process. Before a single machine is turned on they carefully select vendors who supply premium raw materials. All vendors must provide a Certificate of Analysis for each raw material as a continued measure of quality. These certificates are then verified through random in-house and independent laboratory testing. Highly sophisticated equipment confirms the purity and potency of every ingredient on their labels. To further diminish any chance of physical, chemical, and microbiological contaminants, they have established and implemented their own Hazard Analysis Critical Control Point (HACCP) program. Quality assurance professionals make routine checks on all storage, blending, and production areas and conduct final inspections daily. Together, these procedures allow Optimum Nutrition to constantly deliver first-rate sports nutrition supplements under the strictest quality control standards known as current Good Manufacturing Practices (cGMPs).

    Customer Satisfaction
    From the beginning, Optimum Nutrition's customers have been their number one priority. While strict quality control, lab testing, and manufacturing under tightly controlled conditions are all very important, they are all done for one reason – to bring you high quality, affordable supplements. They pride themselves on customer loyalty and are pleased to report that nearly all of their first-time customers become devoted patrons. You can be confident that from the moment a product is conceived to the moment it leaves their facility they put only the best into Optimum Nutrition so you only put the best into your body.


    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: Begins 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.

    I purchased this item for a friend who was told by her doctor she needed to gain weight and prescribed her a popular common store stocked premixed competitors product, in which her insurance didn't cover. I compared the ingredients in both and found Serious Mass to have more than the 3 daily servings the doctor had ordered and in just one daily 2 scoop serving made with 2% milk. Serious mass has more added health benefits also. And it's working. Great product.
