    Optimum Nutrition - Pro Complex High Protein Lean Gainer Double Chocolate - 10.16 lbs. (4,620g)

    Don't judge a gainer based solely upon its calories per serving. Because when it comes to gaining lean mass, not all calories are created equally. Unlike typical weight-gain formulas that are loaded with simple sugars and fat, Pro Complex Gainer derives a much higher percentage of calories from protein – 7 premium sources of protein to be exact. By also supplying complex carbohydrates, dietary fiber, medium chain triglycerides (MCTs), digestive enzymes, vitamins, essential minerals, and great taste as well, we’ve created the ideal lean gainer. Pro Complex Gainer was made with quality, not quantity in mind. Because we understand that you want to get big, not fat.

    Beyound The Basics:

    • Ultimate LEAN GAINER Formula
    • 650 Calories
    • Few Sugars7 Superior Proteins Including Whey, Casein, and Egg
    • High Protein to Carb Ratio
    • Mixes Effortlessly with a Blender, Shaker, or Spoon
    • Easy to Drink
    • The Ingredients That Make Up The Mass

    Ingredients That Make Up the Mass

    • High Quality Proteins:
      Pro Complex Gainer is comprised of high biological value proteins, which means they are easily digested and absorbed so they provide a full complement of amino acids to support the rebuilding process. Each serving of Pro Complex Gainer provides a 60-gram dose of premium muscle-building protein made from 7 unique sources.
    • Complex Carbohydrates & Lipids:
      Carbohydrates and lipids (fatsand oils) provide sustained energy that help prevent proteins from being burned as fuel. Each serving of Pro Complex Gainer provides 85 grams of carbohydrates and 4-5 grams of fiber with only 5 grams of sugar. In addition Pro ComplexTM Gainer supplies medium chain triglycerides (MCTs) and other energy-dense lipids.
    • Micronutrients:
      Various vitamins and essential minerals are utilized during the growth process. Without these micronutrients
      your body cannot effectively process proteins, carbohydrates, or fats. Each serving of Pro Complex Gainer provides 26 vitamins and essential minerals.
    • Calories:
      To gain just one extra pound, you need to consume approximately 3,500 calories—above and beyond what you normally consume through foods, beverages, and supplements. Pro Complex Gainer provides over 600 calories per serving. By adding just one serving to your daily routine, you can begin to experience an increase in lean mass within the first week.
    • Pro Complex Gainer:
      Quality Mass Through Premium Proteins and Nutrient-Dense Calories.

    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.

    I've been trying different protein & gainers over the course of the last 5 years off and on. This stuff is by far the best. It mixes very well with a shaker and fills me up. A huge scoop gives me 700 cal. and 60+ grams of protein. I'm on my third bag of this stuff now - it lasts about a month for me. Last year at this time I was 6'3" 175 lbs... as of yesterday I'm 6'3" 189 lbs.
