Muscle Infusion

Muscle Infusion is an advanced protein formula supplying your muscles with 25 grams of high-quality protein per serving. Rather than just focusing on a single protein source Muscle Infusion is packed with six different proteins. These come in fast absorbing whey proteins as well as slower digesting milk and egg protein fractions. Together they provide a fast yet sustained supply to your muscles.†

Muscle Infusion is high in essential amino acids which are the true building blocks of muscle. It’s a great source of glutamine and it delivers over 5 grams of pure BCAAs per serving. Each scoop is also fortified with a comprehensive vitamin and mineral spectrum. Special protein digesting enzymes have been added to help ensure a most efficient turn-over from nutritional protein to muscle protein.†

To support your quest for lean muscles, Muscle Infusion is very low in fats and carbohydrates. It tastes absolutely delicious and mixes easily with a spoon.†

I've tried many protein powders, this is definitely top tier. I have been ordering Nutrex products for at least 4 years, never disappointed

Okay, Muscle Infusion Black does taste great – that I cannot deny. As soon as I tried it, I thought I was in love…until I found myself on the toilet for 30+minutes. I wouldn’t consider my stomach to be sensitive, and my fiancé’s tummy is definitely a tank…but he had the same experience as I did. Soooo….not sure how much protein I’m actually absorbing when it’s shooting out the back end (sorry for being graphic).

Happy with my Switch

Nutrex Muscle Infusion Black is probably the most UNDERRATED protein, ever. I used to take Intek, but it’s too damn expensive. So I switched to Nutrex Muscle Infusion Black – not only is it CHEAPER, but it’s also BETTER than the Intek crap I was taking before: no fillers, no false claims of amino spiking, low carbs, higher protein content. Since I’ve been using it, I’ve had GREAT GAINS in lean muscle mass. Plus, I think Muscle Infusion Black tastes great, Nutrex has a pretty good variety of flavors – I mean, I’m already bringing physical pain (albeit self-induced) upon my body during training, so why should I ALSO have to suffer choking down nasty protein? I say, pick your battles. Definitely #StickingWithNutrex #MuscleInfusionBlack

Very Impressed, Nutrex!

I’ve been competing for a little over 9 years, and Nutrex Muscle Infusion Black is undoubtedly the best protein I’ve tried (and trust me, I’ve tried many). Nutrex has really put together an impressive blend of essential vitamins and minerals into Muscle Infusion Black. Tastes great, mixes well, and has a solid protein and nutrition composition. In my opinion, Nutrex Muscle Infusion Black is sufficient enough to use as small meal replacements during cutting season.
