GNC’s exclusive brand, Rival Us have put out one of the most clue full promotional images ever. The pre-workout supplement is a part of the new Blaq Series. It’s image suggests the title will consist of the word ‘gun’ and have the effect of both a thermogenic and PWO. Judging by the size of the tub and other products from their line up, it should be a concentrate without bullshit. Look out for contents like citrulline, caffeine, maybe DMAE and some yohimbe for the burn.
