QA QUALITY ASSURED
General Statements: All Other Content
Muscle & Weight Gainer was designed for anyone who is serious about gaining quality mass and strength, but doesn't want to sacrifice their nutrition plan by eating loads of fatty foods and other unhealthy junk. Each serving is scientifically designed to provide your body with exactly what it needs to recover from intense training and come back stronger than ever.* Specially selected nutrients provide both immediate and sustained energy and protein synthesis.* Fast & Slow Protein Blend Muscle & Weight Gainer provides over 50 grams per serving of premium quality whey, casein and egg proteins - which are all great natural sources of essential aminos and BCAAs. Whey protein provides fast-acting support after exercise or whenever you need it to quickly stimulate protein synthesis and kick-start recovery.* Casein proteins digest slower, providing a "time released" effect to help reduce protein breakdown.* A good source of fiber works synergistically with casein to extend the "time released" effects even further.* Quality Carbs Each serving is packed with quality carbs needed to replenish muscle glycogen stores after exercise.* Hard training can deplete glycogen levels, which are needed to fuel muscle contractions and also provide a cell-volumizing effect.* The carbohydrates within Muscle & Weight Gainer also work synergistically with whey and casein to boost protein synthesis after exercise.* Balanced Levels of Fat Muscle & Weight Gainer contains approximately 10% of calories from fat! Formulas that are too high in fat may slow down your progress and wreck your body composition.
