Experts on background and overview · 5 cited mentions
"Caffeine I think the endurance dosage has gone up to like 4 mg per kilogram up to 8 mg per kilogram. So it can go to like 800 to maybe 1,000 mg of caffeine and it's been studied in humans for improving endurance outcomes."
"people abstain from caffeine for weeks it works better and then they take one serving of caffeine 4 to 600 mg and it really shows the boost of performance that way."
"You don't need four servings of caffeine per day. You don't need pre-workout with caffeine."
