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. Cold brew coffee and water. 320mg of caffeine. Zero sugar. Zero artificial sweeteners. Zero proprietary blends.
What the Research Actually Says About Pre-Workout Caffeine
The International Society of Sports Nutrition position stand on caffeine recommends 3-6 mg/kg of body weight, ingested roughly 60 minutes before exercise. For a 180 lb lifter, that is 246-492mg. Bare Brew 320mg sits right in the middle.
A 2025 meta-analysis in Frontiers in Nutrition found caffeine significantly improved mean power output and mean velocity during resistance exercise.
The takeaway: 320mg of caffeine from cold brew coffee consumed 30-60 minutes before training puts you in the research-backed sweet spot.
Why Cold Brew Beats Pre-Workout Powder
Pick up a tub of C4 Original: beta-alanine, creatine monohydrate, L-arginine, anti-caking agents, sucralose, and acesulfame potassium. Now pick up Bare Brew: cold brew coffee and water.
Most active ingredients in powder pre-workouts are either underdosed or have weak evidence. The only ingredient with robust acute performance data? Caffeine.
Cold brew is also 60% less acidic than hot brewed coffee.

Who Actually Needs 320mg Pre-Workout
If you weigh 120 lbs and are caffeine-sensitive, 320mg might be too much. Drink half the can.
But if you are a 160-220 lb lifter spending $1.50-$2.00 per serving on pre-workout powder, 320mg from two ingredients is exactly what the research recommends.
Powerlifters: Peak caffeine without the gut bomb. Lower acidity means no mid-set nausea.
CrossFitters: Sustained energy across a 20-minute metcon, not a 45-minute crash.
Bodybuilders in contest prep: Zero calories, zero sugar, still hitting PRs in a caloric deficit.
Endurance athletes: Clean caffeine without the crash.
The Money Math
C4 Original: $1.00/serving for 150mg. To hit 3-6 mg/kg at 180 lbs, you need two scoops = $2.00 and double the artificial ingredients. Bare Brew: 320mg in a single can. No math required.
How to Use Cold Brew as Your Pre-Workout
Timing: 30-60 minutes before training. Caffeine peaks around 45 minutes post-ingestion.
Dose: Full can (320mg) for 150-230 lbs. Half can for lighter athletes.
Stacking: Take creatine separately (3-5g daily). Your pre-workout only needs caffeine, timed correctly.
