USN B4 Bomb Extreme is a revamped version of the original (succesful) B4 Bomb, designed to give the most exhilarating workouts possible for maximum results!

Addressing the taste issues of its prequel, B4 Bomb not only tastes good it combines a triple blend of potent stimulants that provide both rapid energy increases but then sustains it over a long period of time thanks to the inclusion of the caffeine like compound Theacrine. Add in the synephrine yielding Advantra Z and B4 Bomb Extreme is actually significantly more potent than any other British preworkout we have ever come across.

USN have also added in the popular amino acid Citrulline, a popular choice for increasing muscle endurance and pumps making B4 Bomb Extreme not just something to smash out a PB but also a preworkout that lets you perform better at high reps and even interval training and cardio. With the addition of Creatine for improved strength and D-Aspartic Acid for hormonal support, B4 Bomb Extreme delivers like few preworkouts with multiple pathways harnessed to increase performance levels.

If you want to improve your stamina, strength and muscular pumps then USN have made this possible by utilising a hardcore blend of stimulants, nitric oxide enhancers and ingredients proven to increase cognitive function. Each serving contains 300mg Caffeine to push you through the hard workouts and will help you smash through plateaus.
