Originally founded in 1997, Medical Research Institute (MRI) is a California-based company that develops a wide range of nutraceuticals for performance enhancement, muscle development, and recovery. Perhaps their most popular supplement is Black Powder pre-workout formula, which introduced ACTINO2S IR, a whey peptide fraction that breaks down fat and provides a nitric oxide boost.
Products
MRI offers more than a dozen different product categories, ranging from fat burners to an athletic training micronutrient and an amino acid formula. Check out some of their more popular supplements here:
Black Powder Ultra
If you haven't taken a look at Black Powder in a while, the potent blend of nitric oxide and fat-burning synephrine has been enhanced in the new Ultra formula with caffeine, taurine, and mucuna pruriens. Black Powder Ultra supports muscle protein synthesis while simultaneously activating fat for burning and providing an energy boost to push through an intense workout.
Athlete Multi Tri-System
Tri-System is taken once in the morning, at noon, and at night to fully cover the daily micronutrient requirements of an athlete in training. It includes the full range of vitamins and minerals designed for peak bioavailability and in the enhanced quantities needed by those who regularly engage in strenuous exercise.
Immune Fit
Immune Fit was designed to support those who train and compete at high levels. In addition to requiring a higher level of nutritional intake, hard training puts added stress on the immune system (not to mention increased risk of infection from the sweat left behind on equipment by inconsiderate slobs at the gym). Immune Fit counters immune system stressors with a unique Co-H20 Intra/Post Recovery formula designed for all-day protection.
Beta Charge
Beta Charge is MRI's essential amino acid formula. It provides an 8:1:1 ratio of leucine-rich branched-chain amino acids (BCAAs) with the enhancement of beta alanine, sodium, and potassium bicarbonates. It provides the fuel for recovery and growth that muscles need, in a choice of three natural-tasting flavors: orange, peach mango, and fruit punch.
SURGE
MRI SURGE reduces muscle damage during exercise while providing enhanced energy, focus, and blood flow with a MyoCarn Power Complex formula that floods the system with nitric oxide and nutrients optimized for muscle absorption.
MRI will be sponsoring the 2014 Texas Shredder Classic along with PricePlow. This annual fitness, bodybuilding, and bikini competition takes place on April 12 in Austin and is open to all.
MRI company standards
MRI has developed a solid reputation thanks to their high standards of quality and purity in product development. Their facilities are certified and their products are randomly tested by the Banned Substances Control Group and National Science Foundation.
