Best Pre-Workout Cold Brew: 320mg Caffeine, Zero Sugar, Zero BS
Your pre-workout has more ingredients than your post-workout meal. Time to fix that. The best pre-workout cold brew is the one with the fewest ingredients and the most caffeine per dollar. That is not a philosophy - it is math. The supplement industry has spent two decades convincing lifters they need neon-colored powder with 40-ingredient labels. Meanwhile, the actual performance research says one thing matters: caffeine dosage and timing. Everything else is marketing. So I built Bare Brew around that idea. Two ingredients.
