MRI came out with their whole red series over the Christmas period and apparently they are not wanting to go on break just yet. Their pre-workout Black Powder has an upgrade on it’s way, Black Powder Ultra. There is no information on what is going to be in it but energy fans are not the only ones who should be happy. T-Fuel X4 and MuscleFuse X4 are two others that MRI have planned for release. T-Fuel is looking to be the new dominate face for the testosterone market and MuscleFuse could well be a replacement for their post-workout WAR. Hopefully there will be more details in the coming weeks.
