USN B4 Bomb is an explosive, high-potency pre-workout powder belonging to USN’s legendary Hardcore Series. Formulated with scientifically grounded nutritional technology, it is specifically engineered to maximize energy output, enhance mental sharpness, and crush training plateaus. This scientifically advanced formula features a transparently dosed matrix of pump-inducing amino acids, cell volumizers, and innovative botanical focus agents. Rather than relying solely on cheap stimulants, B4 Bomb utilizes premium, patented adaptogens like Zynamite® (Mango extract) and Bacowize® (Bacopa extract) to prolong energy levels without causing a sudden post-workout crash. Typically available in 180g and 300g tubs (providing 12 to 20 maximum servings), this sugar-free powder delivers a refreshing, juice-style beverage texture.
