54g protein + 70g carbs + 5g creatine all-in-one shake

USN Muscle Fuel Anabolic delivers 54g of protein, 527kcal, 70g of carbohydrates and 3.7g of fat per 150g serving (two scoops). The all-in-one formula includes 5g creatine monohydrate, 1.1g beta-alanine, 1.1g L-glycine, 850mg HMB, 300mg taurine and 300mg L-glutamine per serving. This is a post-workout stack and high-protein shake combined in a single product.

At 54g protein per serving USN Muscle Fuel Anabolic sits among the highest-protein all-in-ones in the category. Creatine monohydrate at 5g is the studied daily dose shown to increase physical performance in successive bursts of short-term, high-intensity exercise. HMB at 850mg is included for its role in reducing muscle protein breakdown during high training frequency. Beta-alanine at 1.1g contributes to carnosine buffering of muscle acidity over repeated use. The protein source is a blend including whey and casein fractions for combined fast and slow release.

Muscle Fuel Anabolic occupies the crossover between a mass gainer and a protein shake: it is not a high-calorie 1000kcal gainer, but at 527kcal per serving with 70g carbohydrates it is substantially more than a lean whey. The integrated creatine and HMB layer means users save on the cost of separate creatine and recovery supplements. USN has been producing Muscle Fuel Anabolic as one of its flagship all-in-one products for many years, and the formula is updated periodically - the current version reflects the 2024 nutrition data.

Built for bodybuilders and serious gym-goers running a lean bulk or body recomposition phase who want protein, performance actives and post-workout carbohydrates in a single shake. Not suited to anyone who prefers to track and control each supplement ingredient independently. Contains milk and soy. Check label for full allergen details.

Whey-based alternative: XL Nutrition XTRA Mass Gainer 5.2kg (50g protein, 1000kcal per 260g scoop) for trainees wanting whey-protein-led mass gainer.

Frequently Asked Questions

What is Muscle Fuel Anabolic All-In-One Protein Powder & Muscle Builder best used for?

USN Muscle Fuel Anabolic All-In-One Protein Powder & Muscle Builder is best used between meals or after training, when the additional protein and calories fit naturally into your daily intake. Treat it as a meal replacement or supplement rather than an extra on top of full meals. Timing matters less than hitting your overall calorie and protein target for the day.

When should I use Muscle Fuel Anabolic All-In-One Protein Powder & Muscle Builder?

Most people use products in this category after training, between meals or at another point in the day where higher calorie intake is easiest to repeat. Consistency matters more than chasing one exact timing rule.

Can I mix Muscle Fuel Anabolic All-In-One Protein Powder & Muscle Builder with milk?

Yes, mixing with milk adds extra protein and calories per serving and creates a thicker, creamier texture. Water keeps the calorie count lower and makes it easier to drink quickly. Most people choose based on whether they want to increase or control total daily intake from each shake.
