 Prolab’s Lean Mass Complex


Prolab's Lean Mass Complex is a meal replacement shake mix featuring an exclusive 40-40-20 ratio of protein, carbs and fat. Specially designed for people wanting to build a leaner, healthier body, it delivers a proprietary mix of 40 grams of protein, 40 grams of carbs and 20 grams of fat to promote lean muscle gain and fat loss. Lean Mass Complex includes a protein blend, amino acid glutamine, whole grain complex carbohydrates, MCTs (medium chain triglycerides) and essential vitamins and minerals.

Lean Mass Complex features a blend of fast and slow absorbing proteins including whey protein concentrate and isolate, micellar casein and calcium caseinate. These proteins contain optimal concentrations of amino acids to support positive nitrogen retention (stored muscle protein). Whey is quickly metabolized in the body while casein is slower digesting. Glutamine becomes an essential amino acid if demand for glutamine (such as intense exercise) exceeds the body's ability to produce it. Lean Mass Complex synergistically promotes a sustained flow of amino acids for the growth and repair of lean muscle.

Lean Mass Complex's whole grain, fibrous, complex carbohydrate sources include oat flour, brown rice and barley. These whole grain carbs are low GI (glycemic index) foods that help maintain healthy blood sugar levels and support stable energy levels. Delivering 4 grams of dietary fiber, they also promote fat loss and digestive health. MCTs are "good" fats that promote fat metabolism, leanness and positive nitrogen retention.


Lean Mass Complex's 40-40-20 ratio of protein, carbs and fats provides balanced nutrition for building and maintaining lean muscle mass and a lean, healthy body. It features a cinnamon oatmeal flavor and conveniently mixes instantly without requiring a blender. Lean Mass Complex does not contain high glycemic index carbs (sugars such as fructose, sucrose or corn syrup), hydrogenated oils, trans fats or aspartame.

Lean Mass Complex has the following benefits:

  • An exclusive 40-40-20 ratio of protein, carbs and fats
  • Fast and slow absorbing proteins support muscle gain
  • Whole grain carbs and fiber optimize energy levels and promote good health
  • MCTs burn fat and increase leanness


People who are allergic to dairy products should avoid whey protein.
Ingesting MCTs on an empty stomach can cause GI (gastrointestinal) upset.

People with pre-existing medical conditions or taking medication should not supplement with Lean Mass Complex without consulting a physician.
