MuscLean is changing the game on traditional weight gainers. Metabolic Nutrition recognizes that it is not "weight" that you want to gain, rather, you desire to develop lean, hard muscle...all the while, minimizing the accumulation of fat. While traditional weight gainers simply pack on the calories with empty carbohydrate/sugar, MuscLean takes a better approach by combining proven science with macro+micro nutrient technology to help you maximize lean muscle mass, gain muscle weight, improve metabolic functioning, increase strength, while minimizing body fat with a clean calorically dense formula that has very little carbohydrates. MuscLean stimulates muscle development greater than any other weight gainer, making it a critical must have supplement to as consumers who are looking to preserve or maximize their lean muscle mass.

MuscLean differs from traditional weight gainers with a specific "muscle-targeted" approach to weight gain by rapidly increasing lean muscle mass while boosting metabolism providing a faster and more efficient way to add desired lean muscle.

Dedicated to manufacturing high quality nutritional supplements, backed by scientific research and formulated by a medical doctor, Metabolic Nutrition® is the first to introduce a revolutionary lean "muscle" weight gainer designed with high protein, healthy essential fats and low carbohydrates to make it the only true Lean Muscle Gainer of its kind in the marketplace. We introduce to you MuscLean - acclaimed by physicians, athletes and consumers alike. MuscLean's ground breaking formula stimulates lean muscle gain by positively optimizing your body's good hormones' (growth hormone & insulin) response to key macro+micro nutrients while eliminating the effects of catabolic bad hormones (cortisol).

In scientific terms, the secret lies within the uniquely formulated composition and structure of MuscLean, which differentiates it from all the other typical high-carbohydrate/sugar weight gainers.

  • MuscLean's exceptional engineering process preserves the essential protein-peptide structure to improve its potency and effectiveness by encapsulating the protein with 7 of the most powerful and healthy essential fatty acids (rich in Omega 3,6,9 Fatty Acids) which are critical to preserving, stimulating and building lean muscle.
  • Additionally, MuscLean's protein molecules are coated with 8 specifically chosen digestive enzymes which dramatically increase digestion and enhance absorption, thereby eliminating gastric distress and bloating that is common with standard weight gainers.
  • To further enhance your results, MuscLean is fortified with 24 essential vitamins and minerals fueling additional muscle building, stress recovery, and immune boosting ingredients to enhance overall health and wellness.

MuscLean is scientifically engineered for those looking to maximize their health and performance with an uncompromising demand for superior quality.
