The Muscle Bomb® is built for men who want more from every session – whether that’s lifting, cycling, swimming, sprinting, or functional fitness.
You choose your intensity: one scoop to dial in (175mg caffeine), or two for full intensity (350mg). You’re in control.
The formula combines caffeine to enhance alertness and concentration, Citrulline Malate, Beta-Alanine, Taurine, and L-Tyrosine – ingredients trusted by athletes for high-intensity training – plus vitamins B6 and B12, which contribute to the reduction of tiredness and fatigue. With punchy flavours like Lemon Sherbet, Twizzle Lolly, Sour Apple, and Blue Raspberry, it’s a pre-training ritual that delivers on both performance and taste.
When fatigue builds up and focus dips, it’s harder to train with the intensity that drives progress. Left unchecked, that can mean slower sessions, missed lifts, and results that stall.
The Muscle Bomb® changes that. Caffeine has been shown to enhance alertness and concentration. B6 and B12 contribute to the reduction of tiredness and fatigue. Alongside this, the formula includes ingredients like Citrulline Malate, Beta-Alanine, Taurine, and Tyrosine – trusted by athletes worldwide to support high-intensity training.
In the short term, that means sharper focus, greater drive, and the intensity to push harder for longer.
Over time, those sessions stack up. Consistent effort at higher intensity accelerates progress, builds resilience, and keeps you strong, sharp, and capable – today, tomorrow, and in the years ahead.
Mix 10g (1 level scoop) in 200ml or 20g (2 level scoops) in 400ml cold water. Do not take more than 20g per day.
Important: Assess your tolerance before use. Start with 10g (175mg caffeine) and increase only if comfortable.
Do not exceed 400mg caffeine per day.
Not recommended for children, or for women who are pregnant or breastfeeding.
