 So what does that mean in, like, cups of coffee language? So a cup of coffee probably is about 100 to 150 grams of caffeine. Okay. That's a lot. That is a lot. And I would say that performance-wise, it's anywhere from 3 to 6 grams per kilogram. When you get above 6 grams per kilogram at one time, that's a lot of caffeine, and that is not going to benefit your performance.
