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.

The chocolate supreme version of this product is straight gold. This is probably one of my favorite products of all time, not just for casein, but of all supplements I have bought. It dissolves super well (not just "for casein", it dissolves as good as my whey), has a great thick consistency (add water if you want more watery), and the flavor is perfect. It tastes like hot chocolate, without being too sweet that it would ever turn me off from it.

This product is great for building muscle throughout the night. Proteins are not built to taste good. I personally did not mind it because the results are what matters most not the taste.

The casein protein is really good. I think the affect for the product. It the mixing powder is thing so the drink is kind of smooth. I am not a fan of the taste. It is not bad but it is not as good as the other Muscle Tech products I used. It is still a great product

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
