Blood & Guts - 350mg caffeine + 6g Citrulline high-stim pre-workout

DY Nutrition Blood & Guts Pre-Workout delivers 6004mg L-citrulline malate (4340mg citrulline), 4009mg arginine alpha-ketoglutarate, 5500mg beta-alanine, 500mg L-tyrosine, 350mg caffeine anhydrous (plus guarana and green tea contributions), 250mg green tea extract and 47.6mg vitamin B3 per 19g serving. The 380g tub provides 20 sessions.

Caffeine from combined anhydrous and guarana sources provides a layered stimulant profile - anhydrous caffeine delivers a sharp onset, guarana provides a slower-release caffeine fraction that extends the stimulant window. 350mg total caffeine anhydrous is a high-stim dose that suits advanced pre-workout users with established tolerance. L-citrulline malate at 6g drives nitric oxide production for blood flow and muscle pump. Beta-alanine at 5.5g is above the studied 3.2g daily threshold and will produce the characteristic paraesthesia (tingling sensation) particularly in first-time users. AAKG provides a further arginine-based NO pathway contribution.

Blood & Guts is named after Dorian Yates' famous training DVD and reflects the intensity-first philosophy of the DY Nutrition brand. At 20 servings this is a targeted performance product for big training sessions rather than a daily light pre-workout - the 350mg caffeine dose and 5.5g beta-alanine are positioned for maximum-intensity training days. Green tea extract contributes polyphenols with antioxidant activity alongside the caffeine fraction.

Built for advanced gym-goers, competitive bodybuilders and athletes with established stimulant tolerance who want a high-intensity pre-workout for their most demanding sessions. Not suitable for caffeine-naive users, individuals sensitive to stimulants, or anyone under 18. Should not be stacked with additional caffeine sources on the same session. No major allergens declared. Produced in a facility that may handle milk, soy, egg and gluten.

Value alternative: XL Nutrition The Purge 225g delivers 300mg caffeine, 2.5g beta-alanine and 1g L-arginine per 7.5g scoop at £11.99 for 30 servings (just £0.40 per scoop). That's about 60% less per serving than this product's £1.00/serving cost.

Key Benefits

Explosive Energy

Multi-source caffeine from Caffeine Anhydrous, Guarana, and Green Tea delivers fast onset and sustained energy for the most demanding training sessions.

Massive Pumps

L-Citrulline DL-Malate at clinical dose promotes nitric oxide production for enhanced blood flow and skin-splitting muscle fullness.

Extended Endurance

Beta-Alanine buffers lactic acid in muscle tissue, delaying the onset of fatigue and pushing training capacity beyond normal limits.

Sharp Focus

L-Tyrosine and Black Pepper Extract support dopamine and noradrenaline pathways for heightened mental focus and mind-to-muscle connection.
