Viking Labz – Blood Rage (375g)


Hyper-Concentrated Vasodilation & Cellular Swelling

Blood Rage by Viking Labz is an elite, non-stimulant pre-workout formula designed for one purpose: to achieve the ultimate "Valkyrie's Nectar" pump. This hyper-concentrated cellular swelling matrix utilises a massive dose of nitric oxide precursors and osmotic agents to drive plasma expansion and zero-restriction blood flow. Engineered for athletes who want to maximise muscle volume and nutrient delivery without the jitters of traditional stimulants, Blood Rage is the gold standard for skin-splitting vascularity.

Why Blood Rage is the Ultimate Pump Formula:



  • Massive Nitric Oxide Boost: Loaded with 7000mg of L-Citrulline to ensure maximum vasodilation and endurance.

  • Extreme Cellular Swelling: Uses Glycerol (65%) and Agmatine to pull water into muscle cells, creating a high-density, "swollen" look.

  • Enhanced Mind-Muscle Connection: Includes Alpha GPC at a potent 600mg dose to keep you dialled in and focused during every rep.

  • Plasma Expansion Matrix: Features Pink Himalayan Salt and specialised peptides to optimise hydration and blood volume.

  • Absorption Support: Powered by Astragalus and Notoginseng to ensure every milligram of this hardcore formula is utilised by your body.


Unleash the rage and claim your gains with Viking Labz. Available now at Cross the Limits.

Detailed Ingredient Breakdown




  • L-Citrulline (7000mg)
    A powerhouse dose of pure Citrulline that acts as a direct precursor to Arginine. It significantly boosts nitric oxide levels, leading to increased blood flow, improved oxygen delivery, and a massive, long-lasting muscle pump.


  • Glycerol (65%) (2500mg)
    is a potent osmotic agent that forces muscle cells to hold more water. This “hyper-hydration” effect increases muscle volume, providing a thick, full appearance while improving overall endurance.


  • Inositol-Stabilised Arginine Silicate (1500mg)
    A highly bioavailable form of Arginine that stays in the bloodstream longer than standard versions. It works synergistically with Citrulline to maintain peak vasodilation throughout your entire training session.


  • Agmatine (1000mg)
    It is known for its ability to regulate nitric oxide synthase, helping sustain the pump effect and assisting with pain management during high-volume, high-intensity sets.


  • Alpha GPC (50%) (600mg)
    A premium nootropic that increases acetylcholine levels in the brain. This sharpens focus and enhances the mind-muscle connection, ensuring you feel every fibre of the target muscle working.


  • Pink Himalayan Salt (500mg)
    Essential for maintaining electrolyte balance and promoting plasma expansion. It helps prevent cramping and keeps your muscles hydrated and ready for heavy loads.


  • Hydrolysed Casein Peptides (254mg) & L-Norvaline (200mg)
    L-Norvaline inhibits arginase, an enzyme that normally breaks down nitric oxide precursors. By blocking this enzyme, the nitric oxide “valve” stays open even longer.


  • Astragalus & Notoginseng (50mg)
    A specialised herbal complex that improves the bioavailability and absorption of nutrients, ensuring your muscles get the full benefit of the Blood Rage formula.

Viking Labz Blood Rage is an elite, non-stimulant pre-workout pump formula providing 25 servings per container. It is designed to achieve maximum vasodilation and cellular swelling through a hyper-concentrated matrix of nitric oxide precursors and osmotic agents.

Key ingredients include L-Citrulline (7,000mg), Glycerol 65% (2,500mg), Inositol-Stabilised Arginine Silicate/Nitrosigine® (1,500mg), Agmatine Sulfate, and Alpha GPC (600mg). This combination targets nitric oxide production, cellular hydration, and mind-muscle connection simultaneously.

Key benefits include massive nitric oxide production for extreme vasodilation, hyper-hydration through Glycerol-driven cellular swelling, skin-splitting muscle pump and vascularity, improved oxygen and nutrient delivery to working muscles, and enhanced mind-muscle connection through Alpha GPC.

Mix one serving with water and consume 20–30 minutes before training. Due to its stimulant-free nature, Blood Rage can be taken at any time of day without affecting sleep. Follow the recommended dosage on the packaging.

Blood Rage is designed for athletes and serious gym users who prioritise maximum pump and vascularity during training. It suits those who want a stimulant-free pre-workout, those who train in the evening, and experienced users who stack it with a separate energy formula.

Yes. Viking Labz Blood Rage is a completely stimulant-free pump formula. It contains no caffeine or stimulants, making it ideal for evening training and users sensitive to stimulants who still want to maximise pump performance.

As a stimulant-free pump formula, Blood Rage is generally accessible compared to high-stim pre-workouts. However, users should start with the recommended dose and assess their response to high-dose Citrulline and Glycerol before increasing the serving.

Blood Rage uses a 7,000mg dose of L-Citrulline — significantly higher than most pump products — combined with Glycerol 65% for osmotic cellular swelling and Nitrosigine® for bioavailable arginine support. This multi-pathway approach delivers a deeper, fuller pump than single-ingredient formulas.

Yes. Blood Rage is an ideal companion to stimulant pre-workouts or fat burners. Stacking it with a separate energy formula allows users to benefit from both maximum pump support and sustained stimulant-driven energy without ingredient overlap.

Viking Labz Blood Rage Pre-Workout is available through Cross The Limits, an authorised UK retailer. Orders placed before 4pm are dispatched the same day, with free UK shipping on orders over £89.
