ESN Crank Focus - the name says it all

Most of the time, it's more of a gamble, because the extraction of caffeine and L-theanine from the green tea leaf depends heavily on water temperature and brewing time. In addition, seasonal and varietal variations disrupt the 1:1 ratio, while the urge to urinate naturally doesn't take long to kick in when 3 to 4 cups are consumed. To remedy this point, we have developed the ESN Crank Focus capsules, which allow you to quickly, easily, cheaply and thus effectively get the relevant amount of L-theanine and caffeine in the optimal ratio.
