Built for the Graveyard Shift: LSC100 + Night Shift, Gaming & Gym Energy

LSC100 Review video

Curated by The Dose, by LSC100® 15 cards Updated Nov 2026

Night shift nurses, long-haul drivers, gamers grinding past 2am and 5am lifters all run on caffeine. This stack pulls the research on doing it right: when to dose on a night shift, why energy drinks and stacked pre-workouts backfire, what caffeine actually does for esports reaction time, and why caffeine plus a short nap beats fatigue behind the wheel. Sources are NIOSH, FMCSA, NIH, the Sleep Foundation and peer-reviewed studies. LSC100 is a dissolvable lozenge with 100mg caffeine and 100mg L-theanine, sweetened with isomalt and stevia. No water, no shaker, no can. It fits in a gym bag, a scrubs pocket or a cab console.
