PreHD Black is a hard hitting, fast acting, stim-driven preworkout designed for the adrenaline junkies and stim enthusiasts at heart. PreHD Black is a comprehensive formulation containing optimally dosed sensory stimulating and blood flow enhancing compounds that provide unrivaled energy, focus, and intensity, for an unmatched workout experience.
PreHD Black sets a new standard in the high-stim preworkout category — where you feel highest levels of stimulation, focus, and intensity, but still achieve unparalleled muscle pumps and vascularity. We accomplished this using scientifically-dosed patented compounds which synergize to increase nitric oxide production, expand plasma volume, and promote increased muscle blood flow in the face of high stimulation.
