From the UnderGround comes the meanest, most powerful, monstrous lean muscle generating protein to ever surface. Muscle Infusion Black! This daring formula is a unique blend of seven multi-functional protein fractions, each with a different absorption rate and distinct sequence of highly anabolic amino acids. This powerful protein blend is fast acting yet long lasting. It triggers a quick anabolic onslaught followed by sustained muscle building activities. Upon ingestion, it's multi-layered protein fractions go straight to work. They continue to do so for several hours, feeding your muscles with highly anabolic and readily available amino acids.

To further enhance the muscle building properties of Muscle Infusion Black, this wicked formula is loaded with large amounts of BCAA's and Glutamine. Special enzymes have been added to assist your body in absorbing the massive amounts of protein required to get big. Each serving is packed with a comprehensive spectrum of critical vitamins and minerals to assure the most efficient turnover rate from nutritional protein into human muscle protein. To get you on the fast track for building Big Muscles, Muscle Infusion Black comes with very low carbs and fats. Carbs and fats do not build muscle; therefore they have no business in a powerful UnderGround protein formula. Leave it to ordinary protein supplements to be contaminated with useless and waist-expanding fillers.

To get big you need the right protein. Protein is the building block of muscle. Your body builds muscle exclusively out of protein and nothing else. An ordinary protein supplement will give you ordinary results. What you need is a protein that is as close to perfection as can be: Muscle Infusion Black…Your most powerful protein choice from the UNDERGROUND!

  • Muscle Infusion Three Flavors: Chocolate Monster, Cookie Madness, Vanilla Beast
Multi-Layered 7 Protein Fraction Lean Muscle-Building Blend
Ultra-Filtered Instantized Whey Protein Concentrate

A highly Bio-available whey protein that utilizes a high-tech cold manufacturing process with ceramic filters. These ceramic filters remove the fat and lactose isolating the protein without damaging it.

Micro-Filtered Instantized Whey Protein Isolate

This is the purest and most bio-available protein which yields a minimum of 94 grams of whey per 100 grams of protein. This particular form of whey also contains large amounts of Glutamine and BCAA's as well as immunoglobulin's, alpha-lactalbumin, and beta-lacto albumin which are all crucial as immune boosting agents.

Instantized & Hydrolyzed Whey Protein

Hydrolyzed whey is the fastest and most digestible source of protein which is created by using enzymes to "pre-digest", or cut the whey protein into small chunks referred to as peptides. This process of hydrolysis allows up to 80% of the protein to bypass the stomach and be absorbed into the small intestine, allowing the greatest potential for lean muscle tissue. Studies have shown that Hydrolyzed Whey also helps to increase IGF-1, which works closely with Human Growth Hormone in increasing muscle tissue.

Instantized Egg Albumin

Considered nature's most perfect and complete form of protein as it provides all the essential and nonessential amino acids for maximum absorption and assimilation. Egg Albumin is digested slower than whey but faster than casein, acting as a bridge filling in the gaps between the two.

Istantized Micellar Casein

An extremely slow digesting and rich protein source that continues to feed your muscles long after whey proteins have passed through the blood stream. In fact, studies with this un-denatured form of isolated casein protein have demonstrated it to sustain steady amino acid elevations for up to seven hours. It was shown to offer a strong anti-catabolic effect in comparison to faster acting whey proteins. This form of protein supports a longer more sustained positive nitrogen balance compared to other forms of protein.

Istantized Milk Protein Isolate

Contains a mixture of all the protein found in milk (whey and caseins). This type of protein is quite good due to its strong amino acid composition derived from both its whey and casein components. MilkProtein Isolate is second only to pure whey on the biological value scale and has a combination of a relatively fast and slow absorption rate due to the sequence of whey and casein components.

Instantized Calcium Caseinate

This protein is derived from fresh skim milk and is composed of 92% protein. Calcium Caseinate is ideal protein shakes because it adds a thick and creamy consistency. In regards to absorption, calcium caseinate is slow digesting which allows for a sustained and constant flow of amino acids in the bloodstream.

† All proteins contained in the Muscle Infusion blend are instantized. When a protein is instantized, the particles of protein powder are greatly reduced allowing them to mix into a solution easier. This is ideal for individuals who use shaker cups.

            Ordered 5 lbs. of this stuff without ever trying it. I have tried other Nutrex products so I figured I would put my trust in the name of Nutrex. Glad I did! This stuff is priced decent, taste great, and mixes well. I am switching from my previous protien. I use it a hour before I workout, then right after a workout six days a week.

            Reviews about Nutrex Research Muscle Infusion:

            I take about a scoop to a scoop and a half of Muscle Infusion directly after an intense workout at the gym. I also take a scoop to work so I stay full during my shift and keep my body from going through catabolism. I love Muscle Infusion because it is a GREAT tasting protein shake. It tastes like nesquik if you mix it with milk! I don't like how it is a bit chalky, but adding a little more liquid will help with that. I would definitely recommend this protein to any serious lifter or athlete.

Ive been able to tone up my body and build mass over the past few months and I'm not complaining at all about this product! Great price and a great product from an awesome company! Keep up the good work Nutrex!
