USN L-Citrulline Malate is a high-purity, unflavoured performance powder formulated for lifters, runners, and athletes across Australia striving to maximise muscular endurance and skin-splitting muscle pumps. By combining the amino acid L-citrulline with malic acid, this potent compound stimulates nitric oxide production, widens blood vessels, and enhances nutrient-rich blood flow straight to working muscles. Whether you want to grind through extra reps in the gym or stave off fatigue during high-intensity conditioning, USN L-Citrulline Malate provides the pure performance edge you need to push past your limits.

Key Benefits & Features

• Enhanced Nitric Oxide Production: Promotes superior vasodilation to drive intense muscle pumps, vascularity, and intramuscular fullness.

• Delayed Muscular Fatigue: Assists in clearing metabolic by-products such as lactic acid and ammonia, keeping working sets crisper for longer.

• Increased Nutrient Delivery: Expands blood vessels to shuttle essential amino acids, oxygen, and glucose directly into hard-working muscle fibres.

• Pure 2:1 Malate Ratio: Combines pure L-citrulline with organic malic acid to support the Krebs cycle and cellular energy efficiency.

• Unflavoured & Versatile: Mixes effortlessly into any pre-workout, pump formula, intra-workout BCAA/EAA drink, or plain cold water with zero bitter aftertaste.

How It Works

L-Citrulline Malate works by efficiently bypassing liver metabolism to elevate plasma levels of L-arginine—the foundational amino acid required for nitric oxide (NO) synthesis. This elevated NO signalling prompts the endothelial cells lining your vascular network to relax, widening blood vessels and dramatically increasing systemic blood flow. The result is heightened vascularity, engorged muscle tissue, and improved oxygenation throughout demanding training sessions.

The bonded malic acid component plays a crucial secondary role by serving as an essential intermediate in the citric acid (Krebs) cycle, which generates adenosine triphosphate (ATP) for cellular energy. Concurrently, citrulline participates directly in the urea cycle, accelerating the buffering and elimination of toxic ammonia and metabolic waste products. This combined mechanism helps protect working muscles from premature exhaustion, allowing you to train harder with faster recovery between sets.

Recommended Use

Mix 1 level scoop (approx. 3g to 5g) with 200ml to 300ml of cold water, juice, or your preferred pre-workout beverage in a shaker cup. Consume approximately 20 to 30 minutes prior to training. On non-training days, you may consume 1 serving first thing in the morning to support general circulation and daily recovery.
