BACK IN BLACK

From hardcore bodybuilders to household names, everyone knows MRI. We are the brand you’ve known for more than 20 years. We were part of the big bodybuilding boom in the 90s. We were there for every lift, every rep and every win. We always strive to be better, so this year we raised the bar. We stepped back and took a hard look at what we could do better and we did it. We researched, reformulated and rebranded and now we’re back and better than ever.

Our formulas are stronger, our scoops are bigger and our reputation is even better. They don’t build things like they used to—and we’re here to change that. Old school bodybuilding was about hitting the iron, hardcore lifting and setting goals. We got jacked from a bench and a bar, pure nutrition and smart supplements. No nonsense, no cheating and no excuses. We worked for it and we earned it. We’re throwing back to the good ol' no-bull, bodybuilding days and we brought our old school, no nonsense formulas with us. We’re back, baby. Back in Black.

Caffeine

converts homocysteine into methionine which is needed for your body to produce creatine.


Carnosyn® Beta Alanine

enhances athletic performance and exercise capacity helping you build more lean muscle mass. Beta Alanine increases the carnosine levels inside your muscles. Through this increase, you can improve muscle recovery and fatigue post-training.
