  • Endurance

    Hydromax hyper hydrates your muscles to fuel longer workouts and increase muscle pump and fullness. L-Orthinine breaks down fatigue-promoting metabolites so you can train longer and harder.

How To Use The Muscle Builder Stack

Consume one serving of Hydro Isolate first thing in the morning. This is important because you are coming off of a 6-10 hour sleep cycle. In effect, you’ve been fasting for up to 10 hours. Your body will be in a catabolic state, and you need to get it back into an anabolic state. Fast digesting hydro whey protein will do the trick.

You can use your Hydro Isolate Protein to help you meet your protein needs. You never know what life throws your way. You can be prepared by relying on a good hydrolyzed protein to help.

Stack Black Powder® Pre-Workout and NO2 Black® 30 minutes prior to working out.

Finally, for maximum immune protection, enhanced protein metabolism and testosterone support, supplement daily with MRI Performance TRT SUPPORT®.

*Consult your healthcare professional prior to use if you have or suspect a medical condition, are taking prescription drugs or are pregnant or lactating.

Panax Ginseng improves oxygen absorption, reduces blood lactate levels and heart rate and greater leg strength.

When it comes to athletes, zinc is an imperative supplement for optimal performance that prevents early onset fatigue during workouts. The mineral does this by binding to insulin to ensure proper glycogen storage which controls the amount of insulin needing to be produced by the pancreas.

    I have been ordering the TRT and Protein for a few months now and have loved the results. I like the NO2 more than the pre workout so far but am happy with the purchase and opportunity to try everything.
