USN Muscle Fuel Anabolic review – our honest thoughts on this all-in-one protein powder

Muscle Fuel Anabolic

Published by Finn Hayden

A big part of building muscle is being in a calorie surplus as well as consuming enough protein. We've previously looked at a number of mass gainers which can help you to get more calories in your diet, but often these mass gainers are quite low in protein.

This is why we were so intrigued by the Muscle Fuel Anabolic from USN - not only does it contain lots of calories and carbs, but unlike other mass gainers, it's high in protein too. This makes it a sort of 'all in one' type product.

We bought a tub of the Muscle Fuel Anabolic so we could review it in detail, let's get into it:

What's in the Muscle Fuel Anabolic protein powder?

USN Muscle Fuel Anabolic is designed as a comprehensive muscle-building formula, delivering a blend of high-quality protein, carbohydrates, amino acids, vitamins, and minerals. The protein component is a mix of whey protein concentrate and isolate, providing a fast-acting source of amino acids crucial for muscle repair and growth. The inclusion of carbohydrates helps replenish glycogen stores, offering an energy boost for intense workouts.

Muscle Fuel Anabolic ingredients

One notable ingredient is the creatine monohydrate - you get 5g of creatine per serving of Muscle Fuel Anabolic, which is a very good amount. Studies show that consuming 3-5g of creatine per day can help to maintain creatine stores in the muscles, so getting 5g of creatine from each serving of Muscle Fuel Anabolic is ideal.

We also really like that the USN Muscle Fuel Anabolic is actually high in protein, with 54g of protein per serving, unlike the Optimum Nutrition Serious Mass that we reviewed previously.

What does the USN Muscle Fuel Anabolic powder taste like?

You can choose from quite a wide variety of flavours, but we tried the chocolate flavour. It wasn't bad, but definitely not delicious. We've tried much nicer chocolate protein powders, which have a much less artificial taste. We'd be interested to try some of the other flavours, including Cookies and Cream. We wouldn't say that the Chocolate flavour was horrible by any means, it just wasn't particularly nice.


We think that considering everything you get in a tub of Muscle Fuel Anabolic – protein, carbohydrates, amino acids, and more – the product offers good value for money. We paid £40 for a 2kg tub of the powder from Holland and Barrett, which is about the same as we paid for a 2.7kg tub of the Serious Mass powder from Optimum Nutrition. But given that the Muscle Fuel Anabolic is so much higher in protein than the Serious Mass powder, we think it's a very fair price.

Anything else to mention?

Yes - like many of the mass gainers and meal replacement shakes that we've tried, the Muscle Fuel Anabolic powder is pretty thick, and actually quite hard to get down sometimes.

Final thoughts

Overall we'd say that Muscle Fuel Anabolic from USN is an excellent product for people who want a supplement that will help them consume more calories and more protein. Our main criticism would be the taste and how thick it is, which can be a little hard to get down sometimes.
