The Bigger Picture of Lean Gainers: 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 its calories from protein, 7 premium protein sources 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. The 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 (fats and 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. Pro Complex Gainer supplies MCTs and other energy-dense lipids. Micronutrients: each serving of Pro Complex Gainer provides 25 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. Pro Complex Gainer provides over 600 calories per serving.
