Blood and Guts is a pre-workout nutritional supplement designed to boost focus, energy and strength during physical exercise, enabling you to push past your mental and physical limits.Our goal with Blood and Guts was to create a product that embodies Dorian's famous training philosophy and his exceptional work ethic. That's why the revolutionary Blood and Guts pre-workout contains solid doses of key nutrients, fused together through Dorian's lifelong experience, to create the most intense pre-workout supplement on the market today.The ability to generate powerful muscular contractions, sustain focus and concentration, as well as optimise the body's physiological responses are all part-and-parcel of intensity. But most people don't train with the correct intensity, leaving muscular growth poorly optimised post-workout with little reason for the body to adapt.Dorian Yates' Blood and Guts formula puts intensity at the forefront of your training sessions.
