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®.

Tribulus Terrestris Extract
Tribulus Terrestris is a small leafy plant. Both the root and fruit of the plant have been used for medicinal purposes. Studies show that Tribulus prevents a decrease in athletic performance by stimulating testosterone production. It increases activity of protein synthesis and muscular mass and facilitates recuperation after physical loads. By altering testosterone levels, it also increases sexual function and libido.
Fenugreek
