Re: When to Kill Cliff
You can pretty much drink them whenever. You can also substitute them for a Redbull with vodka or drink them during a heavy night of drink or the day after.
Generally I would drink them before or during training sessions. Unless you are sensitive to caffeine, you probably won't feel too buzzy. It's only 25mg of caffeine where Redbull is 75 or 80 per equivalent can.
