Additional Information

Precision Engineered has pioneered the manufacture of premium sports nutrition supplements. Our commitment to quality is the highest in our industry. Every product undergoes rigorous analysis for purity, potency, safety and freshness. We guarantee it.

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. For hardgainers that need as many nutrients as they can get and are not concerned with fat intake, mix with whole milk for increased total calorie intake. Use in conjunction with an intense daily exercise program and a balanced diet including an adequate caloric intake.

Store at room temperature.
