I just read this article:

And then read this synopsis of the data from the study:

I'm thinking about adding caffeine to my PWO supps...especially on leg day. I can't wait for them to repeat the study with a reasonable amount of caffeine. 8mg per kg of bodyweight is a LOT. Most of the data they present is at a pretty high significance level. I didn't realize the study was done several months ago until I checked the dates.
Does anybody else have an opinion about this?
