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.


NITRO-TECH® CASEIN GOLD has the competition beat – with more protein per scoop, less carbs and more servings!

Good products, will be reordering. I purchased the creamy vanilla and chocolate supreme to use as my post lift night-time protein shake. The powder blends great, super smooth and decadent flavor.

I used to like the creamy vanilla casein until they switched to the gold formula and changed the label. This stuff has an awful after taste. I tried mixing it with milk, water and even blended it with a banana and in oatmeal with other fruit and it is still awful. I gave it several tries thinking it was just me but could not do it anymore. I threw my container away and will never buy again. I have used a lot of different proteins and this is hands down the worst tasting one I have ever used.

Not sure how it could get much better. Casein can clump. This one looks like it might out of the tub, but the good part about that is it's not too "dusty," referring to protein whose particles are so small that you have protein dust any time you try to scoop or work with it. However, once you get it in the shaker, it mixes up great (not clumpy), as well as tasting pretty **** good. The vanilla is better than vanilla flavors of yesteryear, and the chocolate is up there with the best I've had. As for how it works, well I'm an ectomorph, so it'll take more time. But, seems to stave off soreness as good as most. So, I'm happy.

I just used this for the first time with water and had no clumps. I may have shaken mine a little too vigorously because it was a little frothy. The flavor was better than I expected and I liked how subtle it was. (I was worried that it was gonna be super sweet.) Overall I bought this because I wanted the benefits of using a casin protein, so the flavor is an added bonus.

The consistency of Cookies and Cream is horrrrrrible. I stir forever and the clumps never go away. So disappointed. I literally cannot drink it because its so clumpy.
