Muscle Nation Custard Casein Protein Combo contains:

  • Muscle Nation Custard Casein Protein 1KG
  • Muscle Nation Custard Casein Protein 1KG

Casein is a dairy protein that is slowly digested by the body. This is due to the formation of a clot inside the stomach, which will take longer to be digested. Because of the slow release, this type of protein is ideal to be ingested before bed or throughout the day when you go for long periods of not refuelling the body.  Muscle Nation has crafted a casein protein, which is made of 90% casein and concentrate delivering 25.2g of complete protein to the body. Custard Casein Protein has no filler, gums or creamers so you can rest assured you have a high-quality product.  Sprint Fit loves the taste and feels like a guilt free treat. 

Muscle Nation Custard Casein Protein features:

  • Support calorie processing. When you combine this product with the right diet and exercise plan tailored to your fitness goals, you will see better results. 
  • Support body composition goals by providing the body with slow-release protein so you can refuel the body with the right nutrients for an extended period of time.
  • Have a slowly digested product as casein takes longer to be digested by the body, making this product great to be taken before bed or throughout the day.
  • Consume a high protein and low fat and carb product ideal for when you are watching your calorie intake.

Golden Ice Cream

    10/10 Vanilla

    Right. I'm one of those people that's tried every damn protein under the sun. I hate whey even in a smoothie and pea protein makes me gag. Let's face it, it's hard to find one you say "shit thats nice". But this vanilla custard IN A SMOOTHIE with berries and spinach and almond milk is the gooooods. It makes it a vanilla THICCshake. It's not bad on its own either especially heated with blueberries. Super good as a protein fix at the end of the day.

    10/10 Golden Ice Cream

    Best protein I’ve ever tasted. Golden ice cream with very cold water tastes exactly like a milkshake!!
  • 5/5

    10/10 Vanilla

    So SO good!! I look forward to this at the end of every day and it’s way more versatile than you would initiate think, I like to mix in fruit/ spreads depending on my mood. Have already ordered the sample pack to try them all out!
  • 5/5

    10/10 Choc Cherry

    10/10 Chocolate Hazelnut

    Love this whole range, and this flavour is no exception. Tastes great, and the coconut chunks are a nice addition

    10/10 Banana

    Delivery was super quick. I made mistake ordering a wrong favor but they were helpful and sent me a correct one. Thank you.

    8/10 Double Chocolate

    I was really surprised by this as I struggle with drinking protein. The custard is a thick consistency, but you can make it thinner by adding more milk. I got the chocolate flavour, which was delicious. I just was not a huge fan of the crunchy chocolate inside, but that’s only because I don’t like crunchy bits in smooth things. Does have a taste of artificial sweetener, but I got used to that.

    10/10 Golden Ice Cream

    10/10 Cookies & Cream

    7/10 Coconut Caramel

    8/10 Chocolate Banana

    This is by far the best protein I have used, flavour and consistency wise. I just use water and a couple ice cubes and it’s perfect! All the flavours a good but the 2 that stand out are golden icecream and the cookies and cream
  • 5/5

    8/10 Rocky Road

    Rocky Road is one of my favourite flavours. It mix’s well and the marshmallows are an extra treat. Definitely recommend 10/10
