Product Overview



Features Miceller Casein, 8-Hour Sustained Release, No Gritty Texture

For over 20 years, NITRO-TECH® has led the way in protein innovation. Built on a foundation of human research and cutting-edge science, it’s earned the trust of countless consumers worldwide. Now the same research and development team has pioneered a new formula based on superior protein sources, quality and manufacturing. Introducing NITRO-TECH CASEIN GOLD – an advanced formula with multiple premium casein sources for optimal digestion rate and superior BCAA profile!


Enhance your recovery with sustained nutrient release. Casein and milk protein are some of the slowest-digesting proteins available. NITRO-TECH® CASEIN GOLD delivers 24g of high-quality protein taken from multiple premium casein sources for a prolonged amino acid release to feed your muscles for up to 8 hours. What’s more, each enhanced serving of NITRO-TECH CASEIN GOLD contains 10g of naturally occurring BCAAs, glutamine and precursor, and only 1g of sugar. Combined with an award-winning flavor profile, NITRO-TECH CASEIN GOLD is as good for your taste buds as it is for your muscles!


The protein source used in NITRO-TECH CASEIN GOLD has been shown in research published in The American Journal of Clinical Nutrition to release amino acids into your bloodstream for up to 8 hours after taking it. With the sustained-release property, the highly anabolic and anti-catabolic formula promotes a musclebuilding environment for longer periods of time!

Each bottle of NITRO-TECH® CASEIN GOLD is fully disclosed to guarantee that you are getting the exact amount of real protein that is displayed on the label.


Enjoying a great-tasting formula doesn’t mean you have to deal with excess carbs and fat. For some companies, the taste of their protein is the only thing they have going for them, so they load up their protein formulas with cheap proteins that are easy to flavor, and then chase that with a load of flavoring in the form of sugar, carbs and fat. At MuscleTech®, we believe that you shouldn’t have to sacrifice macronutrients for taste. That’s why our research team works closely with some of the top protein-flavoring professionals in the world! In fact, we conducted taste tests to help us formulate a best-in-class NITRO-TECH® CASEIN GOLD taste profile we know you’ll love.

In addition, our research team has been able to avoid the pitfalls of many casein products, and engineered NITRO-TECH CASEIN GOLD to be easier to mix with less grit and superior taste and texture than standard casein products.

The result is a smooth, great-tasting formula that doesn’t pack the extra sugar and carbs you’ll see in other protein powders. This gives you more protein per scoop and a better overall macronutrient profile.

Flavor Splash - Chocolate and Vanilla

To ensure a high standard of quality and purity, each batch of NITRO-TECH® CASEIN GOLD undergoes strict quality control and is third-party tested and verified to ensure that each bottle meets the highest standards of purity, quality and consistency.

I will not buy the Vanilla ever gain. To me it tastes like Robitussin medicine with a vanilla aftertaste. I actually dread drinking this. The chocolate is much better. The Cookies and Cream even better than that. Say, where is the ole Cookies and Cream?!

Great casein. The flavor is extremely overwhelming, though. Cookies and cream is too sweet and has a chemical aftertaste.

The chocolate tastes ok. I take at night before bed. I am stronger when I lift the following morning. I didn't think taking casein would make that much of a difference, however it really does. It doesn't mix well without a blender bottle. If you don't have one, get one. It would be nice if there were more than chocolate and vanilla available on

first time to write a negative review of a product on this site. It does not mix at all -- hopeless in a shaker, and even with a high-speed blender it clumps on the side. The vanilla has a sickly artificial taste -- somewhat forget the vanilla extract

I love This product! It mixes easily, tastes great, and has all the essentials that I look For in a protein. You must get this one!!

This was by far the best tasting casein protein powder I've used. I've tried many other brands and this is the best one by far. The texture of the product mixes easily and I didn't even have to use a shaker cup. I used this product with water, milk, and chocolate milk and all three tasted perfect. Throughout the night I always wake up hungry, but drinking this product before bed felt me feeling full throughout the night. I would recommend this product and I will continue to use this product before bed. Disclaimer: Muscle Tech provided me with a free product in return for my honest review.

Flavor I tried the cookies and cream flavor. Honestly, the flavor was not bad, but I have had a lot of other cookies and cream proteins that tasted better and tasted more like “cookies and cream”. I find that the flavor in Casein proteins just is not the same compared to whey and isolate proteins. Mixing with milk or chocolate milk helps. Miscibility The texture when mixed is slightly on the thicker/clumpy side but is comparable to other products. Mixing in a shaker cup does take care of most of the clumps. I like to mix it with milk or chocolate milk and make a somewhat pudding like texture with it by not adding so much liquid. Satiety I definitely, woke up feeling much fuller when using this product before bed. This is thanks to the 8-hour sustained release properties of the miscellar casein (actually 5 different types of casein proteins). Other Pros I like that the product has 10 grams of BCAAs including glutamine for recovery. I was also surprised that it only has 100 calories, which is great compared to other casein proteins.
