Key Benefits & Features

• Multi-Stage Protein Matrix: Combines fast- and medium-release protein sources to trigger immediate muscle protein synthesis while sustaining long-term tissue repair.

• Massive Muscle Support: Delivers a concentrated dose of high-biological-value protein per serving to support serious hypertrophy, strength gains, and lean mass retention.

• Rich BCAA Profile: Naturally packed with essential Branched-Chain Amino Acids to combat exercise-induced muscle breakdown and reduce delayed onset muscle soreness (DOMS).

• Smooth & Indulgent Consistency: Engineered to blend effortlessly into a thick, milkshake-style drink that satisfies dessert cravings without excessive sugars.

• Versatile Daily Anabolic Boost: Ideal for immediate post-exercise recovery, in-between meal hunger control, or an easy macro-booster added to your morning oats and smoothies.

How It Works

USN Beast Protein operates by supplying the muscular system with a continuous flow of essential building blocks via its multi-phase protein blend. Rapid-digesting fractions are swiftly broken down into circulating amino acids, flooding starved muscle fibres directly following intense resistance training to jumpstart cellular recovery. Meanwhile, slower-digesting fractions take over to maintain positive nitrogen balance over an extended window.

This sustained delivery prevents muscle catabolism and optimises the mTOR signalling pathway, creating an ideal anabolic environment for damaged muscle tissue to rebuild thicker and stronger. Formulated with carefully selected dairy proteins and refined for easy digestion, Beast Protein absorbs efficiently without causing excessive heaviness or sluggish gastrointestinal distress.

Mix 1 to 2 scoops (approx. 35g to 70g) with 250ml to 450ml of cold water or low-fat milk in a shaker cup. Shake thoroughly for 20 to 30 seconds until completely dissolved.

• Post-Workout: Consume within 30 to 45 minutes after training to maximise recovery and muscle repair.

• Between Meals: Enjoy 1 serving as a high-protein snack to help hit your daily macronutrient targets and curb mid-day hunger.
