Which USN mass gainer is best for your goals?
When it comes to serious muscle gain, USN is one of the most trusted supplement brands in the UK. Two of their most popular mass gainers are USN Hyperbolic Mass and USN Muscle Fuel Anabolic — both engineered for size, strength, and recovery.
But which one is right for you? In this guide, we break down the key differences, nutritional profiles, and benefits of each product so you can make the best choice for your goals.
USN Hyperbolic Mass – High-Calorie Mass Gainer
USN Hyperbolic Mass is designed for hardgainers and athletes with fast metabolisms who struggle to put on weight. It delivers huge calories per serving, packed with protein, carbs, creatine, and amino acids to fuel muscle growth.
Key Features
51g protein per serving (whey concentrate, isolate & milk proteins)
High-carb blend (maltodextrin, dextrose, fructose) to fuel training & replenish glycogen
Creatine, glutamine & taurine for strength and recovery
Tolerase™ L enzyme for easier digestion (great if you usually feel bloated on gainers)
Best For: Skinny guys or hardgainers who want a true mass gainer with higher calories and carbs.
USN Muscle Fuel Anabolic – All-in-One Lean Gainer
USN Muscle Fuel Anabolic is marketed as an all-in-one performance shake. It combines high-quality protein, creatine, amino acids, and a full vitamin/mineral blend. With slightly fewer carbs and sugars than Hyperbolic Mass, it’s more of a lean gainer and recovery shake.
Key Features
55g protein per serving (5 premium sources: whey, milk, soya, egg, caseinate)
77g carbs (26g sugars) for energy and recovery
5g creatine, beta-alanine, HMB, BCAAs for performance & recovery
Full spectrum vitamin & mineral blend
Versatile timing — pre- or post-workout
Best For: Athletes and beginners who want a balanced, all-in-one muscle-building shake rather than a very high-calorie gainer.
